(a) Steps of pyocyanin extraction with or without 0.5 μg/mL of AgNPs. Complete inhibition in productivity was observed. (b) Quantification of pyocyanin levels of P. aeruginosa upon treatment with AgNPs. (c) Inhibition of alginate production (left side) by P. aeruginosa after treatment with 0.5 μg/mL of AgNPs. The negative control (right side) showed hyper-mucoviscosity by string test. ***is highly significant at P < 0.0001.
