Role of biologically synthesised nanoparticles in environmental pollution remediation



Environmental pollution is serious threat for all living organisms. Nanoparticle synthesis using green approach is a non-toxic, easy and energy saving process. Varieties of species have the unique capability to synthesize commercially useful nanoparticles from various metal salt precursors that can help in environmental remediation. The combination of nanotechnology and bioremediation is known as Nanobioremediation. Researchers have shown that biologically nanoparticles shows great potential in reducing environmental pollution from water and soil by adsorption of pollutants and harmful toxic substances from their environment .These green nanoparticles can convert toxic chemicals into less toxic form. Studies also shown that metal nanoparticles also help in removal of harmful bacteria and fungi from environment which can cause diseases in living system. Green synthesised nanoparticles shows very promising results when it comes to environmental remediation they have been used as dye degrader,Oil degrader, photocatalytic agents, biosensors, heavy metals and persidtent organic particulate (POPs) absorbers etc. This review focus on the current status of different types of biologically synthesised nanoparticles in environmental pollution from different species and future challenges associated with environmental remediation.
