Nanoparticles for Bioremediation of Heavy Metal Polluted Water

The process of bioremediation can be intrinsic or natural attenuation, where the process of remediation happens on its own, or it can be extrinsic or bio-stimulated when it is incited with help of some growth productive conditions like addition of fertilizers or nanoparticles, the smallest active particles on the earth. Nanoparticles are charged entities with low activation energy and exhibiting quantum effects making the chemical reaction between the nanoparticle and surrounding feasible in lesser time, and they also exhibit surface plasmon resonance that helps in identification of toxic material in surrounding. Apart from these properties, their different shapes and sizes help in designing the environmental cleanup process as per the suitable conditions and requirements. Polluted water treatment is being done with the help of nanoparticles due to their property of being highly profitable as adsorbents and for filtration purposes.
