Polyphenol-based antibacterial and antioxidative nanoparticles for improved peritonitis therapy
The development of advanced sustainable biomedical materials with superior biosafety and bioactivity for clinical applications is highly desirable. In the present investigation, biomass-based nanoparticles (NPs) were assembled through the Mannich reaction between the plant polyphenols and the broad-spectrum antibiotic tigecycline (TG). The fabricated NPs with uniform size demonstrated excellent oxidative balance effects, pH-responsive release properties and antibacterial performances. Furthermore, the intracellular and in vivo studies confirmed that the NPs are capable of reducing oxidative damage to cells and significantly repairing tissue injury in mice with peritonitis. This work presents an effective method and idea for constructing biomass-based materials for the treatment of infection-induced diseases.
