Low temperature atmospheric pressure plasma sources for microbial decontamination

Low temperature atmospheric plasma for microbial decontamination

Low temperature Plasma (LTP) is a high-energy gas that is created when an electrical current is passed through a gas. Until recently, plasmas could only be created at relatively high temperatures in a vacuum and the use of plasma on sensitive materials such as human tissue, food products, medical devices and the packaging industry, was therefore impractical. However, over the last few years tec...

Microbial Decontamination of Spices Using Cold Plasma

Most of spices are produced using traditional systems. In unsanitary conditions, spices can contain large numbers of pathogenic microbes such as bacteria, molds and yeasts. Some microorganisms are known as human pathogens, which need disinfection mechanisms that minimize their potential harms to active substances in spices. Use of contaminated spices in foods can significantly decrease the shel...

Mycotoxin Decontamination of Food: Cold Atmospheric Pressure Plasma versus “Classic” Decontamination

Mycotoxins are secondary metabolites produced by several filamentous fungi, which frequently contaminate our food, and can result in human diseases affecting vital systems such as the nervous and immune systems. They can also trigger various forms of cancer. Intensive food production is contributing to incorrect handling, transport and storage of the food, resulting in increased levels of mycot...

Non-thermal atmospheric pressure plasma sources for biomedical applications

It was presented that various types of non-thermal atmospheric pressure plasma sources operated with low frequency(~kHz) or microwave frequency feeding argon or helium gas, or in the ambient air could be used for the treatment of cancer cells, sterilization, tooth whitening, and blood coagulation. The antibody-conjugated GNPs enhanced to kill cancer cells exposed to plasmas. The plasmas treatme...
