In vitro antibacterial test results of BP nanosheets against E. coli bacteria evaluated by colony counting method after 12 hours of treatment. (A) The colony-forming units of control sample without any BP nanosheets. (B) The colony-forming units with the treatment of 50 μg/mL of exfoliated BP nanosheets. (C) The colony-forming units with the treatment of 100 μg/mL of exfoliated BP nanosheets. (D) Bactericidal efficiency of BP nanosheets at different concentrations. The error bars represent ± standard deviation for n = 3. *, p < 0.05 evaluated as statistically significant for 50 µg/mL and 100 µg/mL BP nanosheet concentration as compared with control (0 µg/mL) sample after Bonferroni–Holm’s correction. #, P < 0.05 evaluated as statistically significant between 50 µg/mL and 100 µg/mL BP nanosheet concentration after Bonferroni–Holm’s correction.
