Cold atmospheric pressure plasma jets (CAPPJs) have antifungal and anti-inflammatory properties. This study evaluated the effects CAPPJs in preventing systemic fungal dissemination in a murine model of oral mucositis associated with candidiasis.

Despite the excellent properties of silicone endotracheal prostheses, their main limitation is the formation of a polymicrobial biofilm on their surfaces. It can cause local inflammation, interfering with the local healing process and leading to further complications in the clinical scenario. The present study evaluated the inhibitory effect of cold atmospheric plasma (CAP) on multispecies biofilms grown on the silicone protheses' surfaces.

- - The plasma jet transfer technique utilizes a conductive wire at floating potential to ignite a plasma plume inside a flexible tube for surface modification of polypropylene (PP) samples using argon gas.
- - Two configurations were tested: one with a thin copper wire directly in the gas flow and another with a metallic mesh that creates a dielectric barrier between the plating and gas.
- - Water contact angle (WCA) measurements indicated that the distance between the jet outlet and the PP surface influences the effectiveness of the surface modification, with XPS analysis revealing a relationship between WCA values and the formation of oxygen-functional groups.
