| 3 | Ordered porous metal oxide semiconductors for gas sensing显示文摘Among various gas sensing materials, metal oxide semiconductors have shown great potential as resistive type sensors. The ordered porous structural metal oxide semiconductors with well-defined meso-or macro-pores chemically synthesized via soft-templating method and nanocasting strategy have high porosity, highly interconnected pore channels and high surface area with enormous active sites for interacting with gaseous molecules. These features enable them good performance in gas sensing,including high sensitivity, fast response and recovery, good selectivity. This review gives a comprehensive summary about the porous metal oxides with focus on the synthesis methods, structure related properties, as well as the modification strategies for gas sensing improved performances. | Xinran Zhou Xiaowei Cheng Yongheng Zhu Ahmed A.

| 4 | Enhancement of gemcitabine against pancreatic cancer by loading in mesoporous silica vesicles显示文摘Gemcitabine(Gem) is currently the first-line chemotherapeutic drug in management of pancreatic cancer, however the therapeutic efficacy of Gem is limited due to its short half-life and poor cell membrane permeability. Here we designed mesoporous silica vesicles(MSVs) with large pore sizes as a novel drug delivery system. The MSVs were synthesized using cetyltrimethyl ammonium bromide(CTAB) as a structure-directing agent, tetraethoxysilane(TEOS) as silica source in n-hexane/water biliquid system. By virtue of the large pore size and large pore volume of the MSVs, Gem was loaded into the mesoporous of MSVs via 'nanocasting' method. In vitro drug release experiments of gemcitabineloaded MSVs showed an accelerating release of gemcitabine in acidic condition. These fluorescently labeled MSVs could be effectively internalized by both a human(BxPC-3) and a mouse pancreatic cancer cell lines(Pan02). Additionally, some MSVs could even reach the nuclei of the pancreatic cancer cells. Cell viability assays demonstrated that gemcitabine-loaded MSVs exhibited enhanced anticancer activity in inhibiting the proliferation of Bx PC-3 and Pan02 cells compared with free Gem, while the MSVs alone showed no significant cytotoxicity. Our results indicate that our synthesized MSVs might represent a promising novel drug delivery platform for the treatment of pancreatic cancer. | Jun-Tao Dai Yu Zhang Heng-Chao Li Yong-Hui Deng Ahmed A.
