From: Silver and Gold Nanoparticles Alter Cathepsin Activity In vitro
Ag-NP effects on purified cathepsin B and L enzymes. Ag-NPs were incubated with purified cathepsin B (a) or L (b) enzymes. The amount of cathepsin activity in the treatment groups is expressed as percent control and plotted as the mean +/- SEM. Fluorescence was determined using a fluorescent plate reader (*P < 0.05, n = 6).
