Abstract
This invention discloses a laser assisted cold plasma device for overcoming the antimicrobial resistance and effectively killing the microbes. The microbes are first illuminated with laser light, which inactivates the antioxidant enzyme of the microbes and renders them susceptible to reactive oxygen species (ROS) attack. The microbes are then treated and killed with cold plasma. The synergy between the two treatments improves the effectiveness of microbe eradication by several orders of magnitude.
