Back Cover: A core–shell-structured zeolitic imidazolate framework@cationic antimicrobial agent templated silica nanocomposite for tackling antibiotic resistant bacteria infection

Abstract

An anti-drug-resistant bacteria core-shell structure is designed, containing antibacterial zeolitic imidazolate framework-8 (ZIF-8) as the core and bactericidal benzalkonium chloride (BAC) templated rough-surface mesostructured silica nanocomposite (RMSN) as the shell. The resultant ZIF-8@RMSN nanocomposite exhibits sustained release of BAC and zinc ions, leading to enhanced antibacterial and biofilm elimination properties against drug-resistant bacterial. In addition, ZIF-8@RMSN modified antibacterial band-aid possesses excellent anti-drug-resistant bacterial infection properties both in vitro and in vivo (e523).
