Figure 6From: Enhanced antibacterial and anti-biofilm activities of silver nanoparticles against Gram-negative and Gram-positive bacteriaDetermination of size and shape of AgNPs. The size and morphology of AgNPs were determined using transmission electron microscopy. TEM micrograph of AgNPs prepared from A. cobbe (A). The average particle size was found to be 5 nm.
