Nano science is multidisciplinary field that involve the design and Engineering of functional system at the molecular scale.it is field applied science focused on the synthesis and application of material and device on Nano scale. Nano science is the matter at Nano scale materials having structured components with at least 1–100 nm dimensions. Nanoparticles are the great interest to their extremely small size and high surface to volume ratio. The nanoparticles are synthesized by physical, chemical and Green or Biological methods. Nanoparticle's to world wide application in area of Engineering, electronics, environments, medicinal drug delivery, Biotechnology, Biosensors, cosmetics and material science. In this review paper mentioned that in metal nanoparticles especially Gold and silver nanoparticles their synthesis and their therapeutic application of number of diseases suchas Cancer, Diabetes, Parkinsons, Alzheimers, HIV/AIDs, Athritis, Hepatitis, Cirrohsis, Spinal Cord, Injury, Tuberculosis and CVS disorders and also their biomedical application. We also mentioned the Green synthesis is and their toxicological limitations of metal nanoparticles.
