Reactive Metal Boride Nanoparticles Trap Lipopolysaccharide and Peptidoglycan for Bacteria-Infected Wound Healing

Generation of an alkaline microenvironment microenvironment enhanced boron dihydroxy groups ability to trap lipopolysaccharides or peptidoglycans through esterification, which enhanced metal cation-induced bacterial death and inhibited dead bacteria-induced excessive inflammation both in vitro and in vivo.
