Harmful microorganisms such as bacteria represent one of the largest threats to human health. Efficient sterilization methods are thus a necessity.

In general, hot temperatures are better suited to killing germs, but that doesn't mean you should start sterilizing everything with heat. "It's not realistic or necessary," says Manish Trivedi ...

In this study, we showed that 310 nm UV-LED irradiation had weak bactericidal effects on oral bacteria but showed low toxicity to gingival epithelial cells. It also induced the production of ROS ...

Irradiation destroys disease-causing bacteria and reduces the risk of food borne illnesses. While it need not sterilise the food – it is still necessary to handle and cook the food properly - ...

Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity.

The researchers cultivate highly productive bacteria by increasing the mutation rate with room temperature plasma irradiation, and then tweak the fermentation process to best suit these optimal ...
