Electrochemically Driven Dissipative Growth of Affinity Hydrogels for Bioresponsive Interfaces
Advanced Functional Materials, EarlyView.Voltage pulses drive the growth and reinforcement of hydrogel films under dissipative conditions. This biocompatible strategy enables efficient integration of affinity ligands into the hydrogel matrix, enhancing the selective capture of growth factors and allowing precise temporal control over their release, making them well‐suited as adaptive ...
