Sol-gel

In the last twenty years Nanoscience and Nanotechnologies have become more significant and have found a lot of applications in many aspects; the synthesis making nanostructured materials with helpful and tunable properties is central to the evolution of nanoscale science and technology. Nanometre scale metal particles exhibit optical, electronic, magnetic and chemical properties which have wonderful technological and scholar value. Among them silver, copper, and gold nanoparticles (NP) offer powerful
