Effect of AgNPs on biofilm inhibition. The anti-biofilm activity of AgNPs was assessed by incubating all test strains with different concentrations of AgNPs for 4 h in a 96-well plate. The results are expressed as the means ± SD of three separate experiments each of which contained three replicates. Treated groups showed statistically significant differences from the control group by the Student's t test (p < 0.05).
