| 1 | Fractal Design Boosts Extrusion-Based 3D Printing of Bone-Mimicking Radial-Gradient Scaffolds显示文摘Although extrusion-based three-dimensional(EB-3D)printing technique has been widely used in the complex fabrication of bone tissue-engineered scaffolds,a natural bone-like radial-gradient scaffold by this processing method is of huge challenge and still unmet.Inspired by a typical fractal structure of Koch snowflake,for the first time,a fractal-like porous scaffold with a controllable hierarchical gradient in the radial direction is presented via fractal design and then implemented by EB-3D printing.This radial-gradient structure successfully mimics the radially gradual decrease in porosity of natural bone from cancellous bone to cortical bone.First,we create a design-to-fabrication workflow with embedding the graded data on basis of fractal design into digital processing to instruct the extrusion process of fractal-like scaffolds.Further,by a combination of suitable extruded inks,a series of bone-mimicking scaffolds with a 3-iteration fractal-like structure are fabricated to demonstrate their superiority,including radial porosity,mechanical property,and permeability.This study showcases a robust strategy to overcome the limitations of conventional EB-3D printers for the design and fabrication of functionally graded scaffolds,showing great potential in bone tissue engineering. | Huawei Qu Zhenyu Han Zhigang Chen Lan Tang Chongjian Gao Kaizheng Liu Haobo Pan Hongya Fu Changshun Ruan | 2021 | Research2021，，1： | 2 |
| 2 | Recent advances in small-scale hydrogel-based robots for adaptive biomedical applications显示文摘Small-scale robots,ranging in size from micrometers to centimeters,have gained significant attention in the biomedical field.However,conventional small-scale robots made of rigid materials encounter challenges in adapting themselves to the soft tissues and complicated environments of human body.Compared to the rigid counterpart,small-scale hydrogel-based robots hold great promises due to their tissue-like low modulus,outstanding biocompatibility and accessible stimuli-responsive capabilities.These attributes offer small-scale hydrogel-based robots with multimodal locomotion and reinforced functions,further enhancing the adaptability in manipulation and tasks execution for various biomedical applications.In this review,we present recent advances in small-scale hydrogel-based robots.We first summarize the design principles of small-scale hydrogel-based robots including materials,fabrication techniques and manipulation strategies,then highlighting their upgraded functions and adaptive biomedical applications.Finally,we discuss existing challenges and future perspectives for small-scale hydrogel-based robots. | Mingzhe Nie Qilong Zhao Xuemin Du | 2024 | Nano Research2024，17，2： | 1 |
