NIR-responsive MXene nanobelts for wound healing
Source abstract
Abstract
Abstract Effectively achieving wound healing is a great challenge. Herein, we facilely prepared temperature-responsive MXene nanobelt fibers (T-RMFs) carrying vitamin E with a controllable release ability for wound healing. These T-RMFs were composed of MXene nanosheets spread along polyacrylonitrile and polyvinylpyrrolidone composite nanobelts together with a thermosensitive PAAV- coating layer. The high mass loading and high surface area of the MXene nanosheets endow the T-RMFs with excellent photothermal properties. The temperature could be easily controlled by near-infrared (NIR) irradiation exposure, and then the thermoresponsive polymeric coating layer relaxed the interface to dissolve vitamin E and promote vitamin E release. The T-RMFs demonstrated excellent biocompatibility and wound-healing functions in cellular and animal tests. The facile method, high mass loading, high surface area, excellent wound-healing functions, interesting nanosheet/nanobelt structure, mass production potential, and NIR responsive properties of these T-RMFs indicate the great potential of our nanobelts for wound healing, tissue engineering, and much broader application areas. This facile nanosheet/nanobelt preparation strategy paves a new way for nanomaterial fabrication and applications.
