Nanotechnology presents a significant risk to health and the environment. Discuss.NanotechnologyNanotechnology is considered a new technology and it has a wide scope of applications, for example, medicine, industry and energy. As it is a new technology, we do not know much about the risks and security of its applications. In this article I will discuss three areas, medicine, industry and energy nanotechnology, and the potential risks they pose. Because they are recent, applications of nanotechnology may worry some people about the safety of its use and the risks it poses for health and the environment. Nanotechnology is a division of technology, science and engineering carried out at the nanoscale. approximately less than 100 nanometers. Since the beginning of the invention of nanotechnology, scientists have tried, through research and experiments, to use it in various fields, because its small scale allows for more efficiency and less material. The result of all the research is that nanotechnology is today involved in many fields such as manufacturing of food and consumer goods, drug delivery, reduction of energy consumption and many more. still others. The field that has benefited the most from the use of nanotechnology is medicine. field. Nanoparticles are used to deliver drugs to certain cells; it helps a lot to fight cancer cells and do more research on them. Research to expand drug delivery continues and the goals are faster, safer and more precise targeting of drugs.
