COLD ATMOSPHERIC PLASMA OXIDATION OF OLIGOSACCHARIDE: ATOMIC LEVEL MODELING
Cold atmospheric plasma (CAP) is effectively used in several medical fields, particularly in the removal of biofilms from
surfaces. However, the molecular mechanisms of CAP effects are still poorly understood. In this study, the mechanisms of
CAP-induced oxidation of oligosaccharides were studied using reactive molecular dynamics (MD) simulations. In particular,
the processes of interaction of reactive oxygen and nitrogen species formed by CAP with cellotriose (a model system for
oligosaccharides) were studied. Simulation results showed that when reactive oxygen particles interact with cellotriose, they
dissociate the structurally important glycosidic bonds of the molecule. This leads to the destruction of the oligosaccharide
molecule. These MD results were in agreement with the experimental results on the oxidation of cellotriose by CAP.
