Figure 2From: Antimicrobial activity of spherical silver nanoparticles prepared using a biocompatible macromolecular capping agent: evidence for induction of a greatly prolonged bacterial lag phaseThe dependence of corrected microbiological lag time ( T corr ) using fresh BHI ( 2A ) or aged BHI ( 2B ) on keratin-capped Ag Np s at four Staphylococcus aureus concentrations whereupon C I = C 0 Φ. All data points represent the mean ( x ¯ ) of 3 replicates.Back to article page
