| 1 | Dual-functional bacterial cellulose modified with phase-transitioned proteins and gold nanorods combining antifouling and photothermal bactericidal properties显示文摘Bacterial cellulose(BC)is one of the most versatile natural biopolymers with unique physical,chemical,and biological features.However,the lack of intrinsic antibacterial property of native BC limits its broad biomedical applications where such property is highly required to prevent contamination or infection caused by attached bacteria.In this work,we developed a simple and facile method to fabricate a dualfunctional BC membrane by physical incorporation of gold nanorods(GNRs)followed by deposition of a phase-transitioned bovine serum albumin(PTB)film.Due to the broad-spectrum antifouling property of the PTB film,the resulting membrane could prevent the adhesion and accumulation of bacteria.A few bacteria that broke through the protection of the PTB film could be eradicated under short-term irradiation of a near-infrared laser due to the excellent photothermal property of incorporated GNRs.The whole fabrication was conducted in a simple and environmentally friendly manner,avoiding complicated processes and toxic organic solvents.Moreover,because all the components were biocompatible,the resulting membrane showed negligible cytotoxicity in vitro and good histocompatibility in vivo.This work thus provided a reliable way to endow BC with antibacterial property,being beneficial for diverse biomedical applications. | Luohuizi Li Guize Li Yong Wu Yuancheng Lin Yangcui Qu Yan Wu Kunyan Lu Yi Zou Hong Chen Qian Yu Yanxia Zhang | 2022 | Journal of Materials Science & Technology2022，，15： | 0 |
| 2 | Photothermal scaffolds/surfaces for regulation of cell behaviors显示文摘Regulation of cell behaviors and even cell fates is of great significance in diverse biomedical applications such as cancer treatment,cell-based therapy,and tissue engineering.During the past decades,diverse methods have been developed to regulate cell behaviors such as applying external stimuli,delivering exogenous molecules into cell interior and changing the physicochemical properties of the substrates where cells adhere.Photothermal scaffolds/surfaces refer to a kind of materials embedded or coated with photothermal agents that can absorb light with proper wavelength(usually in near infrared region)and convert light energy to heat;the generated heat shows great potential for regulation of cell behaviors in different ways.In the current review,we summarize the recent research progress,especially over the past decade,of using photothermal scaffolds/surfaces to regulate cell behaviors,which could be further categorized into three types:(i)killing the tumor cells via hyperthermia or thermal ablation,(ii)engineering cells by intracellular delivery of exogenous molecules via photothermal poration of cell membranes,and(iii)releasing a single cell or an intact cell sheet via modulation of surface physicochemical properties in response to heat.In the end,challenges and perspectives in these areas are commented. | Yangcui Qu Kunyan Lu Yanjun Zheng Chaobo Huang Guannan Wang Yanxia Zhang Qian Yu | 2022 | Bioactive Materials2022，7，2： | 0 |
