Fig. 2From: Effect of silver nanoparticles on the standard soil arthropod Folsomia candida (Collembola) and the eukaryote model organism Saccharomyces cerevisiae GST activity of protein extracts from F. candida treated with AgNPs and AgNO3 determined by means of CDNB as a model substrate. a GST activity of protein extracts from test animals exposed to different concentrations of AgNPs; b GST activity of protein extracts from test animals exposed to different concentrations of AgNO3. Measurements were conducted three times. Error bars indicate standard deviations. Single asterisks indicate significance at P < 0.05; double asterisks indicate significance at P < 0.01 (using ANOVA with Dunnett’s comparison)Back to article page
