Abstract: During the past few years, silver nanoparticles became one amongst the foremost investigated and explored technology derived nanostructures, given the fact that nano silver primarily based materials established to possess attention-grabbing, challenging, and inspiring characteristics appropriate for numerous applications. Generation after generation, the postulates come back forth regarding properties of silver for the traditional Greeks cook from silver pots and the recent saying “born with silver spoon in his mouth” so show that ingestion with a silver spoon was renowned as uncontaminated. Silver has an excessive amount of contemporary industrial uses and is considered as a store of wealth. Silver nanoparticles are unit one amongst the foremost very important and interesting nano materials among many metals like nanoparticles. they need been urban as a complicated unit within the field of nanotechnology. This review predominately focused on advantages and synthesis of silver nanoparticles using physical, chemical, and biological ways. However, physical, and chemical methods are harmful and expensive however the biological technique is easy, rapid, non- noxious and eco- friendly. It additionally explains regarding mechanism of action, numerous characterization techniques as well as UV- Visible Spectroscopy, Localized Surface Plasmon Resonance (LSPR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) spectroscopy, X- ray Photoelectron Spectroscopy (XPS), Dynamic Light Scattering (DLS), Zeta Potential and finally concluded with numerous applications.

Keyword: Silver nanoparticles, synthesis, mechanism, characterization techniques, numerous applications.
