Figure 4.

Antibacterial activity of GO_I-coated surface against bacterial biofilm. Quantitative analysis of bacterial biofilms after treatment of GO-coated surface with E. coli and S. aureus. Graphical representation of percentage biofilm inhibition of E. coli (a) and S. aureus (b). Data represented here shows the statistical difference (p-value < 0.05) between the GO_I-treated and control sample. Parallel experiments were also carried out on a 96-well plate without GO films, which served as a positive control.
