Ionic–Bionic Interfaces: Advancing Iontronic Strategies for Bioelectronic Sensing and Therapy

Advanced Science, EarlyView.
Ionic–bionic interfaces for bioelectronics leverage ions as multifunctional mediators that combine mechanical compliance, ionic and electronic functionalities, and therapeutic effects. These systems offer real‐time biosignal transduction, effective wound dressing, responsive drug delivery, and seamless interaction between soft tissues and electronic ...

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

Advanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

Catalyst‐Free Collagen Filament Crosslinking for Engineering Anisotropic and Mechanically Robust Tissue Scaffolds

Advanced Science, EarlyView.
A bioorthogonal rhodamine/PEG crosslinking strategy is introduced to engineer dense collagen hydrogels with high mechanical resilience and cytocompatibility. Integration with wet‐spinning enables the fabrication of uniaxially aligned, cell‐laden collagen filaments that activate mechanotransductive signaling and support functional muscle regeneration in

Real‐Time In Vivo Cellular‐Level Imaging During Puncture

Advanced Science, EarlyView.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Synchronous force and Ca2+ measurements for repeated characterization of excitation-contraction coupling in human myocardium

Communications Biology
Dysfunctional Ca2+ signaling affects the myocardial systole and diastole, may trigger arrhythmia and cause transcriptomic and proteomic modifications in heart failure.
