Antimicrobial peptide mimetic minimalistic approach leads to very short peptide amphiphiles‐gold nanostructures for potent antibacterial activity

Abstract

AbstractStrategically controlling concentrations of lipid‐conjugated L‐tryptophan (vsPA) guides the self‐assembly of nanostructures, transitioning from nanorods to fibres and culminating in spherical shapes. The resulting Peptide‐Au hybrids, exhibiting size‐controlled 1D, 2D, and 3D nanostructures, show potential in antibacterial applications. Their high biocompatibility, favourable surface area‐to‐volume ratio, and plasmonic properties contribute to their effectiveness against clinically relevant bacteria. This controlled approach not only yields diverse nanostructures but also holds promise for applications in antibacterial therapeutics.
