Injectable, Intrinsically Antibacterial Conductive Hydrogels with Self-Healing and pH Stimulus Responsiveness for Epidermal Sensors and Wound Healing

An injectable, self-healing, conductive chitosan-based hydrogel demonstrates real-time health monitoring and promotes wound healing.

• The hydrogel exhibits pH responsiveness, allowing it to transition between liquid and gel states based on acidity levels.
• It shows self-healing properties, enabling it to recover from damage autonomously.
• Broad-spectrum antibacterial properties are present without the need for additional antibacterial agents.
• Biocompatibility tests confirm the hydrogel's suitability for use in medical applications.
• In a mouse model, the hydrogel significantly enhances wound healing outcomes.
• The hydrogel functions as an epidermal sensor, capable of real-time monitoring of various human activities.
