The electrical microenvironment plays an important role in bone repair. However, the underlying mechanism by which stimulation (ES) promotes regeneration remains unclear, limiting design of microenvironment-specific electroactive materials. Herein, simple co-incubation aqueous suspensions at physiological temperatures, biocompatible regenerated silk fibroin (RSF) is found to assemble into nanofibrils with a β-sheet structure on MXene nanosheets, has been reported inhibit restacking and oxidation MXene. An hydrogel based RSF bioencapsulated thus prepared promote efficient regeneration. This MXene/RSF also acts as piezoresistive pressure transducer, can potentially be utilized monitor electrophysiological microenvironment. RNA sequencing performed explore mechanisms, activate Ca2+/CALM signaling favor direct osteogenesis process. ES facilitate indirect promoting polarization M2 macrophages, well stimulating neogenesis migration endotheliocytes. Consistent improvements angiogenesis are observed hydrogels under vivo. Collectively, provides distinctive promising strategy for osteogenesis, regulating immune neovascularization ES, leading re-establish

Electrostatic Interfacial Cross-Linking and Structurally Oriented Fiber Constructed by Surface-Modified 2D MXene for High-Performance Flexible Pseudocapacitive Storage

ACS Nano, Год журнала: 2023, Номер 17(3), С. 2487 - 2496

Опубликована: Фев. 1, 2023

Fiber supercapacitors are promising power supplies suitable for wearable electronics, but the internally insufficient cross-linking and random structure of fiber electrodes restrict their performance. This study describes how interfacial oriented can fabricate an MXene with high flexibility electrochemical The continuous highly macroscopic fibers were constructed by 2D sheets via a liquid-crystalline wet-spinning assembly. oxyanion-enriched terminations surface-modified in situ could reinforce electrostatic interactions while mediating sheet-to-sheet lamellar within fiber. resultant exhibits electrical conductivity (3545 S cm-1) mechanical strength (205.5 MPa) pseudocapacitance charge storage capability up to 1570.5 F cm-3. Notably, assembled supercapacitor delivers energy density 77.6 mWh cm-3 at 401.9 mW cm-3, exceptional stability exhibiting ∼99.5% capacitance retention under deformation, be integrated into commercial textiles microelectronic devices. work provides insight fabrication advanced development high-performance flexible supercapacitors.
