TITLE:

Eliminiation of Biological Contaminants on Materials with Cold Atmospheric Plasmas

KEY WORDS:

Cold atmospheric plasma, Plasma, Plasma sterilization

SUMMARY:

Plasmas are regarded as the fourth state of matter, and its physical properties allow several applications in the industry, mainly, in surface treatment. This work aims to apply the properties of cold atmospheric plasmas for the sterilization of surfaces, objects, and environments. An atmospheric plasma source has been developed using components-of-the-shelf (COTS), that work with high frequencies, on the order of KHz, utilizing DC-pulsed signals. Simulations were made to evaluate the circuit behavior and then compared with the prototyped circuit. Preliminary results of the biocide action using Peribacillus simplex demonstrate that the plasma source has a biocidal capability after 10 minutes of exposition.
