Morphological Screening of Silver Nanoparticles

A transmission electron microscope (JEM-1400, JEOL model) was used to determine the morphological screening of Ag-NPs. Imaging was recorded by the electronic microscope lab of Cairo University Research Park (CURP). A glow-discharged grid of carbon was used to place freshly prepared Ag-NPs on and left to be air-dried for a few minutes. Then, the shape and surface harshness of the nanocomposite specimens were checked by a TEM-operated system. TEM of the synthesized Ag-NPs by the crude aqueous extract from Moringa and NaBH₄ are shown in Figure 2. They ranged from 4.40 to 12.2 nm in size and they were spherical.
