Absolute inhibition (100%) was also observed on CMA treated with a 50 ppm concentration of AgNPs against C-10. The inhibition effect on CMA was greater than 90% against M-1 treated with a 100 ppm concentration of AgNPs and A-2 treated with 25 and 50 ppm concentrations of of silver nanoparticles, respectively (Table 3,Fig. 1).
