The application is a kind of nanoscale
enzyme multifunctional composite hydrogel and its preparation method and application, belonging to the field of biological
medicine technology. In view of the problem that the existing materials or drugs have poor
treatment effect on
infected wound, the application comprises the following steps: preparing solution A and solution B respectively, standby, preparing Cu-TCPP-Mn
nanosheet, obtaining Cu-TCPP-Mn
nanodot after further treatment, adding the activated Cu-TCPP-Mn
nanodot into solution A to obtain
mixed solution C with a concentration of 5 mu g / mL, adding the activated PRP solution into solution B to obtain
mixed solution D with a concentration of 100 mu g / mL, and mixing the
mixed solution C and the mixed solution D in equal volume to obtain CHPM composite hydrogel. The CHPM composite hydrogel can effectively reduce the
oxidative stress level of acute
infected wound tissue, provide a suitable oxidative microenvironment for PRP to play a role in promoting
angiogenesis, and accelerate the healing of acute
infected wound.
