Tianjin University's Copper-Peptide Nanozyme Gel Speeds Healing of Infected Diabetic Wounds in an Animal Model
Tianjin University researchers designed a peptide, C7-RD(S)HHEEH, that self-assembles with copper ions into a nanozyme mimicking four enzymes, including superoxide dismutase and peroxidase, and added it to a sprayable gelatin hydrogel, reporting in ACS Applied Materials & Interfaces. In a model of bacteria-infected diabetic wounds, the gel sped wound closure and increased new blood vessels and collagen deposition; there is no human data.
