TEM results confirmed the synthesized AgNPs was spherical in shape (Figure 5, A) and the size of AgNPs ranged from 5-45 nm but the average mean size of AgNPs was 20 nm (Figure 5, C). The diffraction pattern confirmed the formation of metallic AgNPs (Fig 5, B). EDS spectrometer analysis confirmed the presence of silver and copper signals. The silver signal confirmed the presence of elemental silver (peak, 3KeV) due to localized surface plasmon resonance and copper signal due to the background of a copper grid (Figure 5, D).
