In this paper, the effect of the BCD plasma on the Escherichia coli （E. coli） bacteria cell wall was investigated through two analytical methods; Adenosine-5-triphosphate （ATP） assay and Atomic Force Microscopy （AFM）. The ATP assay results indicate an increase in the ATP content of samples which were exposed to the BCD plasma. This implies the bacteria cell rupture. Moreover, AFM images confirm a serious damage of the bacteria cell wall under the influence of the bactericidal agents of the plasma.展开更多
