The rapid increase and spread of Gram‐negative bacteria resistant to many or all existing treatments threaten a return to the preantibiotic era. The presence of bacterial polysaccharides that impede the penetration of many antimicrobials and protect them from the innate immune system contributes to resistance and pathogenicity. No currently approved antibiotics target the polysaccharide regions of microbes. Here, describe monolaurin‐based niosomes, the first lipid nanoparticles that can eliminate bacterial polysaccharides from hypervirulent Klebsiella pneumoniae, are described. Their combination with polymyxin B shows no cytotoxicity in vitro and is highly effective in combating K. pneumoniae infection in vivo. Comprehensive mechanistic studies have revealed that antimicrobial activity proceeds via a multimodal mechanism. Initially, lipid nanoparticles disrupt polysaccharides, then outer and inner membranes are destabilized and destroyed by polymyxin B, resulting in synergistic cell lysis. This novel lipidic nanoparticle system shows tremendous promise as a highly effective antimicrobial treatment targeting multidrug‐resistant Gram‐negative pathogens. The first reported instance of a lipid nanoparticle that efficiently targets the polysaccharide regions of Gram‐negative bacteria is described. In conjunction with polymyxin B, the lipid nanoparticle synergistically eradicates polysaccharides via multimodal mechanisms. This promising innovation holds immense potential in countering the escalating challenge of antibiotic resistance in Gram‐negative bacteria.
