Biogenic AgNPs—A Nano Weapon against Bacterial Canker of Tomato (BCT)

Figure 4

TEM images taken after six months of synthesis to show the nanoparticles stability. (a) A scanning TEM dark field image shows particles with white contrast, dispersed across the TEM support film. (b) A high resolution TEM image shows particles of sizes 6–12 nm. Internal structure such as twinning is visible. The lattice planes indicated by the arrow have a spacing of 0.22 nm which corresponds to the 111 type planes in silver.
