Gelatinous silver colloid nanoparticles: synthesis, characterization, and their antibacterial activity

The major method used for synthesis of silver nanoparticles (Ag-NPs) is the chemical wet reduction method. The problem with the chemical reduction method is that the synthetic process is expensive and can also have toxic substances absorbed onto them. To overcome this, the “green” method provides a...
