AI Article Synopsis

  • This study introduces an inexpensive plasma device that employs a 3D-printed design using a parallel-plate dielectric barrier discharge with a metallic mesh electrode.
  • The device operates on atmospheric air without requiring additional gas supply and significantly modifies the surface composition of polyethylene, reducing carbon levels and increasing oxygen after treatment.
  • It effectively reduces microbial load by over 99% within 1 to 10 minutes while maintaining Vero cell viability between 91% and 96%, indicating its potential for material surface modifications and infection control applications.

Article Abstract

This study proposes an affordable plasma device that utilizes a parallel-plate dielectric barrier discharge geometry with a metallic mesh electrode, featuring a straightforward 3D-printed design. Powered by a high-voltage supply adapted from a cosmetic plasma device, it operates on atmospheric air, eliminating the need for gas flux. Surface modification of polyethylene treated with this device was characterized and showed that the elemental composition after 15 min of plasma treatment decreased the amount of C to ~80 at% due to the insertion of O (~15 at%). Tested against and , the device achieved a reduction of over 99% in microbial load with exposure times ranging from 1 to 10 min. Simultaneously, the Vero cell viability remained consistently high, namely between 91% and 96% across exposure times. These results highlight this device's potential for the surface modification of materials and various infection-related applications, boasting affordability and facilitating effective antimicrobial interventions.
