AN OVERVIEW OF NANOTECHNOLOGY'S EFFECTS ON HUMAN LIFE

Life would not be the same without technology. Because of its many practical uses, nanotechnology has recently emerged as the most widely used sector of technology. Nanostructured materials, such as nanoparticles, nanopowders, nanowires, nanotubes, nanorods, nanofibers, dendrimers, nanoclusters, and nanocrystals, are produced in large quantities worldwide because of their potential applications in a variety of fields, including biotechnology, electronics, photonics, medicine delivery, and agriculture. This technique seems to be the solution to the global issues of water and environmental pollution. In addition to the immense benefits of nanotechnology, nanomaterials have negative consequences on human health that must be taken seriously. While some nanoparticles enter the body through the lungs or other organs through food, drink, or medication, they can also affect various organs and tissues such as the kidney, liver, brain, etc. and have cytotoxic effects. Certain nanoparticles can enter the body through breathing and cause damage to lung tissue and chronic breathing problems. The form, size, concentration, solubility, and stability of a nanoparticle all have a significant impact on its hazardous effect and interactions with biological systems. Therefore, it becomes essential to comprehend the risk and expense of any consequent harm while using new technologies. For the sake of society's safety, it is thus essential to research the different nanostructure materials and their human exposure. With an emphasis on their usefulness and toxicity, this paper provides a concise overview of the applications and potential effects of Ag and TiO2 nanoparticles on human health and the environment.
