Notes: aControl (no AgNP, water alone). Means are averages of three replications. Data were subjected to 9 × 3 (AgNP concentration × incubation time) factorial analysis of variance (ANOVA), critical difference (CD) for incubation time is 0.027, CD for AgNP concentrations is 0.468, and that for time × concentrations is 0.81.
