Plasma-based green disinfectants can limit spread of infectious diseases

In News 
  • Researchers have developed a plasma-based disinfectant generated with the help of cold atmospheric pressure plasma (CAP) which could act as a green decontaminant for COVID 19.
About Plasma 
  • Plasma, the fourth state of matter which makes up most of the universe when produced in controlled conditions in the lab and are termed as Cold Atmospheric Pressure Plasma (CAP).
  • The scientists passed plasma forming gases such as Helium, Argon, and Air through a high voltage electric field which led to the formation of a stable plasma with a mixture of ions, and electrons emitting a pink glow of CAP inside the reaction chamber.
About Plasma
  • Short-lived highly reactive oxygen and nitrogen species (ROS/RNS) generated in the plasma led to complete deactivation of the SARS-CoV-2 Spike protein occurs within 2 min of CAP treatment.
  • The RT-PCR analysis has also established that CAP can deactivate the RNA of the SARS-CoV-2 virus.
  • The researchers showed that the CAP, a plasma-based disinfection method is a better alternative to environmentally hazardous chemical-based decontamination methods.
  • The cold atmospheric plasma is environmentally safe since, during the entire decontamination process by plasma treatment, no chemical waste is produced.
