A Review: Impact of Nanotechnology on Human life

Abstract

Abstract: No aspects of life are untouched without technology. Recently, the field of nanotechnology becomes most commercial technology due to its wide range of applications in daily life. The nanostructured materials e.g. nanoparticles, nanopowders, nanowires, nanotubes, nanorods, nanofibers, dendrimers, nanocluster, nanocrystal are globally produced in large quantities due to their wide range potential such as health and skin care, electronics, photonics, biotechnology, drug delivery, agriculture etc. This technology seems to be remedy of environmental and water pollution problems which the world is facing. Apart from vast usefulness of nanotechnology, the nanomaterials have detrimental effects on human life which cannot be neglected and needs proper attention to be paid . Certain nanoparticles can enter the body through breathing may cause damage to lung tissue and chronic breathing problems while some particle enter the body through lungs or other organs via food, drink and medicine and affect different organ and tissues like kidney, liver, brain etc. and may cause cytotoxic effects. The toxic effect and interaction with biological system of nano-particle largely depends upon the shape, size, concentration, solubility and stability. So it becomes necessary while adopting new technology to understand its risk and cost of resulting damage. Therefore, it is necessary to study the various nanostructure materials and their human exposure for the safety of the society. This review gives a brief summary of application & possible impacts of Ag & TiO2 nanoparticles on human life & environment with focus on their utility and toxicity. Keywords: Nanotechnology, Nanoparticles, Environmental pollution, Toxicity.
