Antimicrobial Effects of Thonningianin a (TA)-Loaded Chitosan Nanoparticles Encapsulated by a PF-127 hydrogel in Diabetic Wound Healing.

Background And Purpose: Diabetic wounds are serious chronic complications of diabetes and can lead to amputation and death. Although considerable progress has been made in drugs and materials for treating it, it's still an urgent clinical problem as the materials and drugs have potential therapeutic drawbacks, such as low delivery efficiency and poor tissue permeability. To promote diabetic wound healing, a composite of thonningianin A (TA)-loaded chitosan nanoparticles (CNPS) encapsulated by a Pluronic F-127 (PF-127) hydrogel (TA-CNPS-PF) was developed in this study.
