Figure 3From: Antimicrobial activities of silver nanoparticles synthesized from Lycopersicon esculentum extractAntibacterial activity of AgNP. Antibacterial activity of AgNP having different concentrations: (A) 1, 2, 5, and 10 μg/ml and (B) 20, 50, 100, and 200 μg/ml, with 106 CFU of E. coli inoculated on Luria broth agar plate. The ‘B’ spot in the middle of the agar plate is for the blank test, having no AgNP.Back to article page
