Cold Atmospheric Plasma: An Inside Look Through Optical Diagnostics For Biomedical Applications, Liesl Krause, Ahmed Hassanein, Prasoon Diwakar

The Summer Undergraduate Research Fellowship (SURF) Symposium

An emerging technology for medical applications is cold atmospheric plasma (CAP). CAP is generated using various gasses in a “pen” to create room temperature plasma and then carry the effluents and species. Success has been shown when cold atmospheric plasma is applied to oncology treatments, accelerated wound healing, pathogen disinfection, and various material-changing effects. However, the mechanisms behind these effects are still speculative. This study uses multiple diagnostic techniques including fast photography, two wavelength emission spectroscopy and optical emission spectroscopy to characterize the plasma properties and eventually further test the plasma’s interaction with biological samples. The plume dynamics are observed …
