GermStabbing Particles

摘要

Nanoparticles designed to disrupt the cell membranes of a large group of pathogens, including multidrug-resistant Staphy-lococcus aureus, cause the cells to burst open but don't harm human red blood cells.Because the nanoparticles don't target a specific genetic pathway, researchers hope bacteria will be slow to develop resistance to them. Previous attempts to make polymers that kill microbes by poking holes in cell membranes have raised safety concerns because they tenc to harm some animal cells, too, or they haven't worked as well in the body as they did in a test tube.
