PEC‐DFM Hybrid‐Sensor Based on Nanoparticle‐Resolved Estimation for Sensitive and Reversible Glucose Monitoring

Advanced Science, EarlyView.
Abstract The accurate detection of glucose in wound exudate is critically important for monitoring chronic wound healing. While photoelectrochemical (PEC) sensors are widely used, they often suffer from material degradation caused by redox reactions during operation. Herein, we introduce a dark‐field microscopy (DFM) setup integrated with a PEC system,

Bio‐templated Piezoresistive Yarn for High Sensitivity Movement Monitoring Textiles

Advanced Science, EarlyView.
This study developed a conductive coating by biotemplating silver nanoparticles (AgNPs) onto a Potato virus A (PV) particle network, cross‐linked on co‐polyamide‐starch (CoPA‐SS) coils. The combination of CoPA‐SS's shape memory and PV‐AgNP's piezoresistivity achieved high strain sensitivity and minimal hysteresis.
