Effects of cold atmospheric plasmas on adenoviruses in solution

Experiments were performed with cold atmospheric plasma (CAP) to inactivate adenovirus, a non-enveloped double stranded DNA virus, in solution. The plasma source used was a surface micro-discharge technology operating in air. Various plasma diagnostic measurements and tests were performed in order t...

Description
Summary:Experiments were performed with cold atmospheric plasma (CAP) to inactivate adenovirus, a non-enveloped double stranded DNA virus, in solution. The plasma source used was a surface micro-discharge technology operating in air. Various plasma diagnostic measurements and tests were performed in order to determine the efficacy of CAPs and to understand the inactivation mechanism(s). Different stages of the adenovirus 'life cycle' were investigated--infectivity and gene expression as well as viral replication and spread. Within 240 s of CAP treatment, inactivation of up to 6 decimal log levels can be achieved.
