Smart pH-Sensing Chitosan-Carbon Quantum Dot Hydrogel and Microneedle for Wound Diagnostic Application
Inspired by the wound healing challenges, we reported a chitosan(CS)-derived hydrogel integrated with carbon quantum dots (CQDs) focusing on a biochemical−mechanical regulation synergistic strategy. The modification of CS’s hydrogel matrix by optimized CQD concentration brings a platform with balanced swelling proper...
