In vivo monitoring of multiple biomarkers by functional hydrogels during diabetic wound healing. (a) Glucose response of double network PCHs before and after application to diabetic wound sites. (b) Glucose levels in diabetic wounds monitored by PCHs from 0 to 4 days post injury. Tail vein blood glucose levels was measured as control. (c) pH response of PAM-PR hydrogels before and after application to diabetic wounds. (d) Tracking of pH changes of diabetic wounds by PAM-PR hydrogels during healing. Health mouse wounds were used as control. (e) Temperature response of PAM-B hydrogel before and after application to diabetic wounds. (f) Monitoring of temperature changes of diabetic wounds by PAM-B hydrogel during healing. Health mouse wounds were used as control
