From: Super-antibiofilm effect of N2 plasma treated buffer (NPB) against plant pathogenic bacterium
Inhibitory efficacy of N2 plasma on biofilm of Pst DC3000 according to the treatment time and application methods. The fluorescence microscopy images were obtained after the LIVE/DEAD Bacterial Viability assay on the biofilm treated with plasma. Images in the upper rows are the merge of green (SYTO9, indicating live cells) and red (PI, indicating dead cells), whereas red images in the lower rows are obtained by PI, indicating only dead cells. Application methods used; (a) Direct plasma, (b) Indirect plasma, (c) NPB
