How is plasma sterilization carried out in vitrosolution?

In vitrosolution sterilization has been successively carried out using a combination of low-temperature atmospheric-pressure plasma and the reduced pH method, where the solution is sufficiently acidic. Here, we show the molecular mechanism of such plasma sterilization in solution based on microbiology. Three kinds of bacteria were inactivated by

Mechanism of plasma sterilization in solution

Schematic mechanism of plasma sterilization in solution using plasma-induced chemical processing and the reduced pH method. The ‘target’ of the plasma sterilization corresponds to the test bacteria or the dye-included micelle as a bacterial model. The yellow layer of the target is the cell membrane or surfactant micelle,

Validation of H202 Sterilization | Medical Industry | Humidity

Validation. Sterilization with H2O2 is a low-pressure, low-temperature, nontoxic process with temperatures typically between 6 °C and 60 °C that uses vaporized Hydrogen Peroxide to reduce the level of infectious agents. Aquarius H2O2 is introduced to the vaporizer bowl, heated by RF and fed into the main chamber under vacuum generating plasma.
