AgNPs had been evaluated for anti-biofilm effect on biofilm producing bacteria In this study, AgNPs had a very highly significant antibiofilm effect ( p value < 0.0001) against S. aureus at all concentrations between 250 and 0.9 μg/mL, the maximum biofilm inhibition value 94.36% was achieved at AgNPs concentration 15.6 μg/mL.
