Gold nanoparticles cluster on bacteria and can even kill them, but the clustering patterns and lethality depend on the size of the nanoparticles and the type of bacteria, researchers have found (J. Am. Chem. Soc., DOI: 10.1021/ja301167y).

Understanding how nanoparticles interact with the membranes of bacteria is crucial for developing new antibacterial agents, says
