Chiral Nanoparticle as a New Efficient Antimicrobial Nanoagent

Abstract

d-type functionalized nanoparticles (NPs) can bind to MurD ligase with high affinity and inhibit its peptidoglycan synthetic enzyme activity, and finally cause bacterial killing. In contrast, its L-type counterpart displays a negligible effect, indicating that the chiral structure of the functionalized NPs plays an essential role in their binding interaction with MurD and therefore the antibacterial activity.
