| 1 | Sensitivity-enhanced surface plasmon resonance sensor utilizing a tungsten disulfide (WS_2) nanosheets overlayer显示文摘Tungsten disulfide(WS_2), as a representative layered transition metal dichalcogenide(TMDC) material, possesses important potential for applications in highly sensitive sensors. Here, a sensitivity-enhanced surface plasmon resonance(SPR) sensor with a metal film modified by an overlayer of WS_2 nanosheets is proposed and demonstrated. The SPR sensitivity is related to the thickness of the WS_2 overlayer, which can be tailored by coating a WS_2 ethanol suspension with different concentrations or by the number of times of repeated post-coating.Benefitting from its large surface area, high refractive index, and unique optoelectronic properties, the WS_2 nanosheet overlayer coated on the gold film significantly improves the sensing sensitivity. The highest sensitivity(up to 2459.3 nm∕RIU) in the experiment is achieved by coating the WS_2 suspension once. Compared to the case without a WS_2 overlayer, this result shows a sensitivity enhancement of 26.6%. The influence of the WS_2 nanosheet overlayer on the sensing performance improvement is analyzed and discussed. Moreover, the proposed WS_2 SPR sensor has a linear correlation coefficient of 99.76% in refractive index range of 1.333 to 1.360. Besides sensitivity enhancement, the WS_2 nanosheet overlayer is able to show additional advantages, such as protection of metal film from oxidation, tunability of the resonance wavelength region, biocompatibility, capability of vapor,and gas sensing. | HAO WANG HUI ZHANG JIANGLI DONG SHIQI HU WENGUO ZHU WENTAO QIU HUIHUI LU JIANHUI YU HEYUAN GUAN SHECHENG GAO ZHAOHUI LI WEIPING LIU MIAO HE JUN ZHANG ZHE CHEN YUNHAN LUO | 2018 | Photonics Research2018，6，6： | 8 |
| 2 | Tim-3 promotes cell aggressiveness and paclitaxel resistance through NF-κB/STAT3 signalling pathway in breast cancer cells显示文摘Objective:Although T-cell immunoglobulin and mucin-domain containing molecule-3(Tim-3)has been recognized as a promising target for cancer immunotherapy,its exact role in breast cancer has not been fully elucidated.Methods:Tim-3 gene expression in breast cancer and its prognostic significance were analyzed.Associated mechanisms were then explored in vitro by establishing Tim-3-overexpressing breast cancer cells.Results:In a pooled analysis of The Cancer Genome Atlas(TCGA)database,Tim-3 gene expression levels were significantly higher(P<0.001)in breast cancer tissue,compared with normal tissues.Tim-3 was a prognosis indicator in breast cancer patients[relapse-free survival(RFS),P=0.004;overall survival(OS),P=0.099].Tim-3 overexpression in Tim-3 low breast cancer cells promoted aggressiveness of breast cancer cells,as evidenced by enhanced proliferation,migration,invasion,tight junction deterioration and tumor-associated tubal formation.Tim-3 also enhanced cellular resistance to paclitaxel.Furthermore,Tim-3 exerted its function by activating the NF-κB/STAT3 signalling pathway and by regulating gene expression[cyclin D1(CCND1),C-Myc,matrix metalloproteinase-1(MMP1),TWIST,vascular endothelial growth factor(VEGF)upregulation,concomitant with Ecadherin downregulation).Lastly,Tim-3 downregulated tight junction-associated molecules zona occludens(ZO)-2,ZO-1 and occludin,which may further facilitate tumor progression.Conclusions:Tim-3 plays an oncogenic role in breast cancer and may represent a potential target for antitumor therapy. | Yizi Cong Yuxin Cui Shiguang Zhu Jianqiao Cao Haidong Zou Tracey AMartin Guangdong Qiao Wenguo Jiang Zhigang Yu | 2020 | Chinese Journal of Cancer Research2020，32，5： | 7 |
| 3 | Photonic cavity enhanced high-performance surface plasmon resonance biosensor显示文摘Herein we propose a novel strategy to enhance surface plasmon resonance(SPR)by introducing a photonic cavity into a total-internal-reflection architecture.The photonic cavity,which is comprised of a highly reflective photonic crystal(PC),defect layers,and a gold(Au)film,enables Fabry–Perot(FP)resonances in the defect layers and therefore narrows the SPR resonance width in the metallic surface as well as increases the electric field intensity and penetration depth in the evanescent region.The fabricated sensor exhibits a 5.7-fold increase in the figure of merit and a higher linear coefficient as compared with the conventional Au-SPR sensor.The demonstrated PC/FP cavity/metal structure presents a new design philosophy for SPR performance enhancement. | GUI-SHI LIU XIN XIONG SHIQI HU WEICHENG SHI YAOFEI CHEN WENGUO ZHU HUADAN ZHENG JIANHUI YU NUR HIDAYAH AZEMAN YUNHAN LUO ZHE CHEN | 2020 | Photonics Research2020，8，4： | 4 |
| 4 | Fullerol-hydrogel microfluidic spheres for in situ redox regulation of stem cell fate and refractory bone healing显示文摘The balance of redox homeostasis is key to stem cell maintenance and differentiation.However,this balance is disrupted by the overproduced reactive oxygen species(ROS)in pathological conditions,which seriously impair the therapeutic efficacy of stem cells.In the present study,highly dispersed fullerol nanocrystals with enhanced bioreactivity were incorporated into hydrogel microspheres using one-step innovative microfluidic technology to construct fullerol-hydrogel microfluidic spheres(FMSs)for in situ regulating the redox homeostasis of stem cells and promoting refractory bone healing.It was demonstrated that FMSs exhibited excellent antioxidant activity to quench both intracellular and extracellular ROS,sparing stem cells from oxidative stress damage.Furthermore,these could effectively promote the osteogenic differentiation of stem cells with the activation of FoxO1 signaling,indicating the intrinsically osteogenic property of FMSs.By injecting the stem cells-laden FMSs into rat calvarial defects,the formation of new bone was remarkably reinforced,which is a positive synergic effect from modulating the ROS microenvironment and enhancing the osteogenesis of stem cells.Collectively,the antioxidative FMSs,as injectable stem cell carriers,hold enormous promise for refractory bone healing,which can also be expanded to deliver a variety of other cells,targeting diseases that require in situ redox regulation. | Jielai Yang Jing Liang Yuan Zhu Mu Hu Lianfu Deng Wenguo Cui Xiangyang Xu | 2021 | Bioactive Materials2021，6，12： | 3 |
| 5 | High-performance fiber-integrated multifunctional graphene-optoelectronic device with photoelectric detection and optic-phase modulation显示文摘In graphene-based optoelectronic devices,the ultraweak interaction between a light and monolayer graphene leads to low optical absorption and low responsivity for the photodetectors and relative high half-wave voltage for the phase modulator.Here,an integration of the monolayer graphene onto the side-polished optical fiber is demonstrated,which is capable of providing a cost-effective strategy to enhance the light–graphene interaction,allowing us to obtain a highly efficient optical absorption in graphene and achieve multifunctions:photodetection and optical phase modulation.As a photodetector,the device has ultrahigh responsivity(1.5×10^(7) A/W)and high external quantum efficiency(>1.2×10^(9)%).Additionally,the polybutadiene/polymethyl methacrylate(PMMA)film on the graphene can render the device an optical phase modulator through the large thermo-optic effect of the PMMA.As a phase modulator,the device has a relatively low half-wave voltage of 3 V with a 16 dB extinction ratio in Mach–Zehnder interferometer configuration. | LINQING ZHUO PENGPENG FAN SHUANG ZHANG YUANSONG ZHAN YANMEI LINYU ZHANG DONGQUAN LI ZHEN CHE WENGUO ZHU HUADAN ZHENG JIEYUAN TANG JUN ZHANG YONGCHUN ZHONG WENXIAO FANG GUOGUANG LU JIANHUI YU ZHE CHEN | 2020 | Photonics Research2020，8，12： | 3 |
| 6 | Age-dependent loss of cholinergic neurons in learning and memory-related brain regions and impaired learning in SAMP8 mice with trigeminal nerve damage显示文摘The tooth belongs to the trigeminal sensory pathway.Dental damage has been associated with impairments in the central nervous system that may be mediated by injury to the trigeminal nerve.In the present study,we investigated the effects of damage to the inferior alveolar nerve,an important peripheral nerve in the trigeminal sensory pathway,on learning and memory behaviors and structural changes in related brain regions,in a mouse model of Alzheimer's disease.Inferior alveolar nerve transection or sham surgery was performed in middle-aged(4-monthold) or elderly(7-month-old) senescence-accelerated mouse prone 8(SAMP8) mice.When the middle-aged mice reached 8 months(middle-aged group 1) or 11 months(middle-aged group 2),and the elderly group reached 11 months,step-down passive avoidance and Y-maze tests of learning and memory were performed,and the cholinergic system was examined in the hippocampus(Nissl staining and acetylcholinesterase histochemistry) and basal forebrain(choline acetyltransferase immunohistochemistry).In the elderly group,animals that underwent nerve transection had fewer pyramidal neurons in the hippocampal CA1 and CA3 regions,fewer cholinergic fibers in the CA1 and dentate gyrus,and fewer cholinergic neurons in the medial septal nucleus and vertical limb of the diagonal band,compared with sham-operated animals,as well as showing impairments in learning and memory.Conversely,no significant differences in histology or behavior were observed between middle-aged group 1 or group 2 transected mice and age-matched sham-operated mice.The present findings suggest that trigeminal nerve damage in old age,but not middle age,can induce degeneration of the septal-hippocampal cholinergic system and loss of hippocampal pyramidal neurons,and ultimately impair learning ability.Our results highlight the importance of active treatment of trigeminal nerve damage in elderly patients and those with Alzheimer's disease,and indicate that tooth extraction should be avoided in these populations. | Yifan He Jihong Zhu Fang Huang Liu Qin Wenguo Fan Hongwen He | 2014 | Neural Regeneration Research2014，9，22： | 2 |

| 8 | Distance-controllable and direction-steerable opto-conveyor for targeting delivery显示文摘Opto-conveyors have attracted widespread interest in various fields because of their non-invasive and non-contact delivery of micro/nanoparticles.However,the flexible control of the delivery distance and the dynamic steering of the delivery direction,although very desirable in all-optical manipulation,have not yet been achieved by optoconveyors.Here,using a simple and cost-effective scheme of an elliptically focused laser beam obliquely irradiated on a substrate,a direction-steerable and distance-controllable opto-conveyor for the targeting delivery of microparticles is implemented.Theoretically,in the proposed scheme of the opto-conveyor,the transverse and longitudinal resultant forces of the optical gradient force and the optical scattering force result in the transverse confinement and the longitudinal transportation of microparticles,respectively.In this study,it is experimentally shown that the proposed opto-conveyor is capable of realizing the targeting delivery for microparticles.Additionally,the delivery distance of microparticles can be flexibly and precisely controlled by simply adjusting the irradiation time.By simply rotating the cylindrical lens,the proposed opto-conveyor is capable of steering the delivery direction flexibly within a large range of azimuthal angles,from-75°to 75°.This study also successfully demonstrated the real-time dynamic steering of the delivery direction from-45°to 45°with the dynamical rotation of the cylindrical lens.Owing to its simplicity,flexibility,and controllability,the proposed method is capable of creating new opportunities in bioassays as well as in drug delivery. | Zhen Che Wenguo Zhu Yaoming Huang Yu Zhang Linqing Zhuo Pengpeng Fan Zhibin Li Huadan Zheng Wenjin Long Wentao Qiu Yunhan Luo Jun Zhang Jinghua Ge Jianhui Yu Zhe Chen | 2020 | Photonics Research2020，8，7： | 1 |

| 10 | Honeycomb-Like Hydrogel Microspheres for 3D Bulk Construction of Tumor Models显示文摘A two-dimensional(2D)cell culture-based model is widely applied to study tumorigenic mechanisms and drug screening.However,it cannot authentically simulate the threedimensional(3D)microenvironment of solid tumors and provide reliable and predictable data in response to in vivo,thus leading to the research ilusionis and failure of drug screening.In this study,honeycomb-like gelatin methacryloyl(GelMA)hydrogel microspheres are developed by synchronous photocrosslinking microluidic technique to construct a 3D model of osteosarcoma.The in vitro study shows that ostcosarcoma cells(K7M2)culured in 3D GelMA microspheres have stronger tumorous stemness。proliferation and migration abilitics,more osteoclastogenetic ability,and reistance to chemotherapeutic drugs(DOX)than that of cells in 2D cultures.More imporantly,the 3D-cultured K7M2 cells show more tumorigenicity in immunologically sound mice,characterized by shorter tumorigenesis time,larger tumor volumc,severe bone destruction,and higher mortality.In conclusion,honeycomb like porous microsphere scaffolds are constructed with uniform structure by micofluidic technology to massively produce tumor cells with original phenotypes.Those microspheres could recapitulate the physiology microenvironment of tumors.maintain ell-cell and cell-extracellular matrix interactions,and thus provide an efective and convenient strategy for tumor pathogenesis and drug screening research. | Jiachen He Chichi Chen Liang Chen Ruoyu Cheng Jie Sun Xingzhi Liu Lin Wang Can Zhu Sihan Hu Yuan Xue Jian Lu Huiling Yang Wenguo Cui Qin Shi | 2022 | Research2022，，2： | 1 |
| 11 | Optimized weak measurement of orbital angular momentum-induced beam shifts in optical reflection显示文摘Tiny but universal beam shifts occur when a polarized light beam is reflected upon a planar interface.Although the beam shifts of Gaussian beams have been measured by the weak measurement technique, the weak measurement for orbital angular momentum(OAM)-induced spatial shifts of vortex beams is still missing.Here, by elaborately choosing the preselection and postselection states, the tiny OAM-induced Goos–H?nchen and Imbert–Fedorov shifts are amplified at an air–prism interface. The maximum shifts along directions both parallel and perpendicular to the incident plane are theoretically predicted and experimentally verified with optimal preselection and postselection states. These maximum shifts can be used to determine the OAM of vortex beams. | Wenjin Long Jintao Pan Xinyi Guo Xiaohe Liu Haolin Lin Huadan Zheng Jianhui Yu Heyuan Guan Huihui Lu Yongchun Zhong Shenhe Fu Li Zhang Wenguo Zhu Zhe Chen | 2019 | Photonics Research2019，7，11： | 1 |
| 12 | Tunable spin splitting of Laguerre–Gaussian beams in graphene metamaterials显示文摘Optical spin splitting has attracted significant attention owing to its potential applications in quantum information and precision metrology. However, it is typically small and cannot be controlled efficiently. Here, we enhance the spin splitting by transmitting higher-order Laguerre–Gaussian(LG) beams through graphene metamaterial slabs. The interaction between LG beams and metamaterial results in an orbital-angularmomentum-(OAM) dependent spin splitting. The upper bound of the OAM-dependent spin splitting is found,which varies with the incident OAM and beam waist. Moreover, the spin splitting can be flexibly tuned by modulating the Fermi energy of the graphene sheets. This tunable spin splitting has potential applications in the development of spin-based applications and the manipulation of mid-infrared waves. | WENGUO ZHU MENGJIANG JIANG HEYUAN GUAN JIANHUI YU HUIHUI LU JUN ZHANG ZHE CHEN | 2017 | Photonics Research2017，5，6： | 0 |

| 14 | Resonance-assisted light–control–light characteristics of SnS_2 on a microfiber knot resonator with fast response显示文摘An all-optical light–control–light functionality with the structure of a microfiber knot resonator (MKR) coated with tin disulfide (SnS_2) nanosheets is experimentally demonstrated. The evanescent light in the MKR [with a resonance Q of ~59,000 and an extinction ratio (ER) of ~26 dB] is exploited to enhance light–matter interaction by coating a two-dimensional material SnS_2 nanosheet onto it. Thanks to the enhanced light–matter interaction and the strong absorption property of SnS_2, the transmitted optical power can be tuned quasi-linearly with an external violet pump light power, where a transmitted optical power variation rate ΔT with respect to the violet light power of ~0.22 dB∕mW is obtained. In addition, the MKR structure possessing multiple resonances enables a direct experimental demonstration of the relationship between resonance properties (such as Q and ER), and the obtained ΔT variation rate with respect to the violet light power. It verifies experimentally that a higher resonance Q and a larger ER can lead to a higher ΔT variation rate. In terms of the operating speed, this device runs as fast as ~3.2 ms. This kind of all-optical light–control–light functional structure may find applications in future all-optical circuitry, handheld fiber sensors, etc. | HUIHUI LU ZHONGMIN WANG ZHIJIN HUANG JUN TAO HANQING XIONG WENTAO QIU HEYUAN GUAN HUAZHUO DONG JIANGLI DONG WENGUO ZHU JIANHUI YU YONGCHUN ZHONG YUNHAN LUO JUN ZHANG ZHE CHEN | 2018 | Photonics Research2018，6，12： | 0 |
| 15 | High-sensitivity and fast-response fiber optic temperature sensor using an anti-resonant reflecting optical waveguide mechanism显示文摘Temperature sensing is essential for human health monitoring.High-sensitivity(>1 nm∕℃)fiber sensors always require long interference paths and temperature-sensitive materials,leading to a long sensor and thus slow response(6–14 s).To date,it is still challenging for a fiber optic temperature sensor to have an ultrafast(~ms)response simultaneously with high sensitivity.Here,a side-polished single-mode/hollow/single-mode fiber(SPSHSF)structure is proposed to meet the challenge by using the length-independent sensitivity of an anti-resonant reflecting optical waveguide mechanism.With a polydimethylsiloxane filled sub-nanoliter volume cavity in the SP-SHSF,the SP-SHSF exhibits a high temperature sensitivity of 4.223 nm/℃ with a compact length of 1.6 mm,allowing an ultrafast response(16 ms)and fast recovery time(176 ms).The figure of merit(FOM),defined as the absolute ratio of sensitivity to response time,is proposed to assess the comprehensive performance of the sensor.The FOM of the proposed sensor reaches up to 263.94(nm/℃)∕s,which is more than two to three orders of magnitude higher than those of other temperature fiber optic sensors reported previously.Additionally,a threemonth cycle test shows that the sensor is highly robust,with excellent reversibility and accuracy,allowing it to be incorporated with a wearable face mask for detecting temperature changes during human breathing.The high FOM and high stability of the proposed sensing fiber structure provide an excellent opportunity to develop both ultrafast and highly sensitive fiber optic sensors for wearable respiratory monitoring and contactless in vitro detection. | ZHIBIN LI ZIYE WU ZHUOQI LI LIANGXUN OU WENXIANG ZHANG ZHICONG LAI YU ZHANG MENGYUAN XIE JIEYUAN TANG WENGUO ZHU HUADAN ZHENG YONGCHUN ZHONG XIONG DENG XIHUA ZOU ZHE CHEN JIANHUI YU | 2023 | Photonics Research2023，11，8： | 0 |
| 16 | Modification of Longitudinal Modulus of 3D Full Five Directional Braided Composite Materials Base on Energy Theory显示文摘The aim of this paper is to investigate the longitudinal modulus of three dimensional full five directional (3Df5d) braided composite. First, the analytical model of the internal unit cell is established based on its topological structure. Then, according to the intrinsic relation of different cells, the axial moduli of internal, surface and corner cells are systematically deduced, and the influence of corner-cell periodic discontinuity on the moduli is also analyzed. Finally, considering the actual shape of axial yarns after consolidation, the longitudinal moduli of the different cells are modified based on energy theory. The technology factor λ is also proposed in this modification. The results show that the axial mechanical properties of this material can be strongly designable. The straightness of the axial yarns greatly affects the longitudinal modulus. Technology factor λ is between 1 to 2, corresponding to the minimum and the maximum modulus, respectively. | Apeng Dong Shu Li Wenguo Zhu Jing Pu | 2019 | Journal of Beijing Institute of Technology2019，28，3： | 0 |
| 17 | Side Polished Fiber:A Versatile Platform for Compact Fiber Devices and Sensors显示文摘Side polished fiber(SPF)has a controllable average roughness and length of the side-polishing region,which becomes a versatile platform for integrating multiple materials to interact with the evanescent field to fabricate all-fiber devices and sensors.It has been widely used in couplers,filters,polarizers,optical attenuators,photodetectors,modulators,and sensors for temperature,humidity,strain,biological molecules,chemical gas,and vector magnetic monitoring.In this article,an overview of the development history,fabrication techniques,fiber types,transmission characteristics,and varied recent applications of SPFs are reviewed.Firstly,the fabrication techniques of SPFs are reviewed,including the V-groove assisted polishing technique and wheel polishing technique.Then,the different types of SPFs and their characteristics are discussed.Finally,various applications of SPFs are discussed and concluded theoretically and experimentally,including their principles and structures.When designing the device,the residual thickness and polishing lengths of the SPF need to be appropriately selected in order to obtain the best performance.Developing all-fiber devices and sensors is aimed at practical usability under harsh environments and allows to avoid the high coupling loss between optical fibers and on-chip integrated devices. | Linqing ZHUO Jieyuan TANG Wenguo ZHU Huadan ZHENG Heyuan GUAN Huihui LU Yaofei CHEN Yunhan LUO Jun ZHANG Yongchun ZHONG Jianhui YU Zhe CHEN | 2023 | Photonic Sensors2023，13，1： | 0 |
| 18 | Mineralized manganese dioxide channel as the stent coating for in situ precise tumor navigation显示文摘Drug-eluting stent(DES)is a promising strategy for esophageal cancer.However,full-covered drug-loaded stents cause damage to non-tumor tissue in the esophagus,and the development controlled-release system to prevent non-tumor tissue injure is currently a major challenge.Here,in situ mineralized manganese dioxide coating on Ce6 embedded electrospun fibers covered stent was developed for effective tumor therapy via intraluminal photodynamic therapy(PDT),which could reduce phototoxicity to normal esophageal tissue.Oxidation of manganese ions,which was previously swelled between fibers,was used to accomplish mineralization.After implantation,the manganese dioxide coating in situ reacts with tumor endogenous H^(+) and H_(2)O_(2),which,on the one hand,could effectively alleviate the hypoxic microenvironment which leads to resistance to PDT,and on the other hand,could expose the Ce6-fibers below the coating for intraluminal PDT.In addition,due to the slow degradation of the coating,this stent could own sustained photodynamic performance for up to one month.Notably,the PDT efficiency of the stent was investigated on orthotopic rabbit esophageal cancer models.Overall,this work suggests that in situ mineralized manganese dioxide coated electrospun fibers covered stent may provide a new strategy for advanced esophageal cancer patients as a functional drug delivery platform. | Junyuan Xiao Yiran Zhang Tonglei Fang Tianwen Yuan Qinghua Tian Jingjing Liu Yingsheng Cheng Yueqi Zhu Liang Cheng Wenguo Cui | 2021 | Nano Research2021，14，7： | 0 |
