Fighting listeria and other food-borne illnesses with nanobiotechnology

(EurekAlert) Engineering researchers at Rensselaer Polytechnic Institute have developed a new method to kill deadly pathogenic bacteria, including listeria, in food handling and packaging. This innovation represents an alternative to the use of antibiotics or chemical decontamination in food supply systems. Using nature as their inspiration, the researchers successfully attached cell lytic enzymes to food-safe Read More »
