It is commonly accepted that nanoparticles can kill bacteria; however, the mechanism of antimicrobial action remains obscure for nanoparticles that are unable to be translocated across the bacterial cell membrane by the passive or active processes that exist for mammalian cells. In this study, we demonstrate that the increase of membrane tension provoked by the adsorption of nanoparticles (NP) is responsible for mechanical deformation of the membrane that leads to cell rupture and consequent bacterial cell death. We present a biophysical model of the NP- membrane interactions. The theoretical model suggests that adsorbed NPs can lead to global stretching and squeezing of the membrane. This general phenomenon was revealed experimentally usin...
