Image of the Week

This week’s image come via Microbiology and Immunology, and is of cell lytic enzymes attached to nanoparticles, which are then used to kill listeria!

“Fighting Listeria with Nanobiotechnology: Using nature as their inspiration, the researchers successfully attached cell lytic enzymes to food-safe silica nanoparticles, and created a coating with the demonstrated ability to selectively kill listeria—a dangerous foodborne bacteria that causes an estimated 500 deaths every year in the United States. The coating kills listeria on contact, even at high concentrations, within a few minutes without affecting other bacteria. The lytic enzymes can also be attached to starch nanoparticles commonly used in food packaging.”
