Advanced Science, EarlyView.This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

Ion‐Pair‐Tuned Ionogels for Broad‐Range Linear Pressure Sensing
Advanced Science, EarlyView.Ionogels engineered through ion‐pair tuning extend the linear sensing range of capacitive pressure sensors. By balancing ionic mobility and polarizability within the polymer matrix, this approach mitigates dielectric saturation and maintains a stable pressure response across a broad operating range.

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement
Advanced Science, EarlyView.This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...
