In the last few decades, nanotechnology has come to the fore as a crucial and significant domain in the scientific realm owing to its multidisciplinary nature. The enhanced properties of materials in the nanoscale make them a viable option for different applications in different fields. The conventional method viz. the physical and chemical methods of nanoparticle production, however, pose hazardous risks to the environment. To redress these concerns, researchers have diverted their focus towards the more favourable green method of synthesis which is free from any toxic precursor or strenuous process conditions making it an economical and nature-friendly method. Nanoparticles showed a wide range of application in environmental biotechnology like reduction of pollution, water treatment, remediation, dye degradation and water purification development. This review focuses on the various biogenic precursors for fabrication of nanoparticles and also emphasizes their potential applications in environmental remediation.
