The uprising in materials science has been hosted by before many decades. There has been a significant research interest in the area of using particulate systems to accomplish diverse approaches. The synthesis of material with nanoscale accuracy by means of material science is nanotechnology. Nanoparticles are solid particles, with a size in the range of 1-100 nm. This review intends to present Synthesis of nanoparticles by different approaches also from biological sources here, we discussed different synthesis methods, chemical, physical and biogenic synthesis of nanoparticles. The potential come together between nanotechnology and biological science is enormous. Plants play a key role in the green synthesis of nanoparticles by providing a readily available, eco-friendly, and cost-effective source of reducing and stabilizing agents. Plant extracts, containing various phytochemicals can reduce metal ions into nanoparticles and help maintain their stability. biological method offers a safer and more sustainable alternative to traditional chemical and physical methods for nanoparticle synthesis.
