Acute severe trauma is often associated with rapid blood loss and a high risk of infection. Based on these concerns, this study successfully constructed a multifunctional dual-layer bioactive sponge PCCT with rapid hemostatic and infection-preventing ability. Its external surface is an electrospun poly(lactic acid) (PLA) nanofiber thin film layer, which ensures its high air permeability and effectively protects against external bacterial invasion. In vitro results showed that the film is effectively resistant to invasion by typical Gram-negative (E. coli) and Gram-positive (S. aureus) bacteria. The inner sponge layer was formed by chlorogenic acid (CGA) grafted with chitosan (CS) and loaded with tranexamic acid (TA). The abundant cationic groups on the sponge interacted with negatively charged erythrocytes and achieved rapid hemostasis at the wound site under the action of TA. In addition, the high porosity and bioactivity of the CS-CGA sponge scaffold endowed the hydrogel with good water absorption, antibacterial properties and anti-inflammatory activity, which effectively accelerated the healing of acute infected wounds in rats and demonstrated favorable biosafety.
