Glutaraldehyde (GA), the most widely used crosslinking agent for biomaterials, is cytotoxic. CaCl2 is of particular interest due to its non-toxic nature. Rhein can chelate Ca2+ and promote bone growth. Here we reported a novel nano calcium-deficient hydroxyapatite/O-carboxymethyl chitosan-CaCl2 microspheres loaded with rhein (RH-nCDHA/OCMC-CaCl2 microspheres) using CaCl2 as crosslinking agent for ...... hiện toàn bộ
Anthropomorphism Indexes of the Kinematic Chain for Artificial HandsJournal of Bionic Engineering - Tập 17 - Trang 501-511 - 2020
Immaculada Llop-Harillo, Antonio Pérez-González, Javier Andrés-Esperanza
Anthropomorphic hands have received increasing research interest in the fields of robotics and prosthetics. But it is not yet clear how to evaluate their anthropomorphism. Similarity in the kinematic chain is essential to achieve both functionality and cosmesis. A few previous works have addressed the definition of anthropomorphism indexes, although they have some limitations in its definition. In...... hiện toàn bộ
Deformation and Locomotion of Untethered Small-Scale Magnetic Soft Robotic Turtle with Programmable MagnetizationJournal of Bionic Engineering - - Trang 1-10 - 2024
Lin Xu, Liu Yang, Tao Li, Xingbang Zhang, Jianning Ding
Inspired by the way sea turtles rely on the Earth’s magnetic field for navigation and locomotion, a novel magnetic soft robotic turtle with programmable magnetization has been developed and investigated to achieve biomimetic locomotion patterns such as straight-line swimming and turning swimming. The soft robotic turtle (12.50 mm in length and 0.24 g in weight) is integrated with an Ecoflex-based ...... hiện toàn bộ
Biomimetic hydrophobic surfaces with low or high adhesion based on poly(vinyl alcohol) and SiO2 nanoparticlesJournal of Bionic Engineering - Tập 14 - Trang 476-485 - 2017
Qian Wang, Zhao Dong, Xiaoxia Yan, Yanjiao Chang, Lili Ren, Jiang Zhou
Superhydrophobic surfaces are often found in nature, such as plant leaves and insect wings. Inspired by superhydrophobic phenomenon of the rose petals and the lotus leaves, biomimetic hydrophobic surfaces with high or low adhesion were prepared with a facile drop-coating approach in this paper. Poly(vinyl alcohol) (PVA) was used as adhesive and SiO2 nanoparticles were used to fabricate surface mic...... hiện toàn bộ
3D-printed Mechanically Strong Calcium Phosphate Cement Scaffold with Metformin/Stem Cell-encapsulating Alginate Microbeads for Bone Tissue EngineeringJournal of Bionic Engineering - Tập 19 - Trang 1658-1670 - 2022
Xiong Xiong, Yuanyuan Chen, Rupan Yuan, Gengtao Qiu, Michael D. Weir, Hockin H. K. Xu, Jin Liu, Jianping Ruan, Xiaofeng Chang, Shuxin Qu
The utilization of Calcium Phosphate Cement (CPC) is limited due to its low mechanical strength and difficulty to seed cells deep into the scaffold. The objectives of this study were to: (1) develop a 3D-printed CPC-dopamine-metformin scaffold encapsulating human periodontal ligament stem cells (hPDLSCs), (2) investigate the effect of dopamine on the performance of CPC, and (3) evaluate the effect...... hiện toàn bộ
