Plasma-induced destruction of Candida albicans cell wall components: A reactive molecular dynamics simulation

Cold atmospheric plasma (CAP), as a noninvasive technology, has shown promise in dentistry as it might successfully treat various oral conditions. The antimicrobial capacity of CAP has been proven and it is effective in reducing the main microorganisms responsible for oral infections. Furthermore, CAP has also been explored in the field of tissue regeneration with a great response from both soft and hard tissue. The surface modification ability of CAP is another area of interest, revealing a potential improvement in the osseointegration of dental implants. Additionally, there are other areas within dentistry that have studied the use of CAP, such as surface disinfection, bleaching, and cavity preparation.

In recent years, plasma biomedicine has developed into a new interdisciplinary subject. The interaction between plasma and organisms involves three aspects: “gas–liquid–living organisms.” Molecular dynamics (MD) simulation can simulate the interaction process between plasma and biological tissue with high temporal and spatial resolution. This article reviews the research on plasma biomedicine based on MD simulation and systematically summarizes the progress of MD simulation research on the interaction between plasma and water layer, cell membrane, intracellular substances, extracellular environment, and viruses. These simulations offer a unique opportunity to gain insights into the microscopic mechanisms of these interactions. This article also further looks forward to the opportunities and challenges of MD simulation research.

Molecular understanding of the possible mechanisms of oligosaccharide oxidation by cold plasma

Cold atmospheric plasma (CAP) is a promising technology for several medical applications, including the removal of biofilms from surfaces. However, the molecular mechanisms of CAP treatment are still poorly understood. Here we unravel the possible mechanisms of CAP‐induced oxidation of oligosaccharides, employing reactive molecular dynamics simulations based on the density functional‐tight binding potential. Specifically, we find that the interaction of oxygen atoms (used as CAP‐generated reactive species) with cellotriose (a model system for the oligosaccharides) can break structurally important glycosidic bonds, which subsequently leads to the disruption of the oligosaccharide molecule. The overall results help to shed light on our experimental evidence for cellotriose oxidation by CAP. This study provides atomic‐level insight into the onset of plasma‐induced removal of biofilms, as oligosaccharides are one of the main components of biofilm.
