Alternative approaches that narrow antibacterial specificity towards desired pathogenic bacterial population are of great interest. Here, we report an enzyme-responsive antibiotic-loaded nanoassembly strategy for narrow delivery of otherwise broad-spectrum antibiotics. We specifically target Staphylococcus aureus (S. aureus), an important blood pathogen that secretes PC1 β-lactamases. Our nanoassemblies selectively eradicate S. aureus grown in vitro with other bacteria, highlighting its potential capability in targeting the desired pathogenic bacterial population.NanoscaleSupramolecular antibiotics: a strategy for conversion of broad-spectrum to narrow-spectrum antibiotics for <i>Staphylococcus aureus</i>.PMC7581559GM-136395DP2 AI138238R21 AI144748R35 GM136395T32 GM108556Rangadurai PAnson FThayumanavan SKoyasseril-Yehiya TMSiegrist MSGarcia-Heredia AfalseSupramolecular antibiotics: a strategy for conversion of broad-spectrum to narrow-spectrum antibiotics for <i>Staphylococcus aureus</i>.The propensity of broad-spectrum antibiotics to indiscriminately kill both pathogenic and beneficial bacteria has a profound impact on the spread of resistance across multiple bacterial species.
