Research Paper (postgraduate) from the year 2022 in the subject Physics – Applied physics, grade: 10.0, , language: English, abstract: Nanoscience is the study of things that happen at the nanoscale. This means that different structures, devices, and systems must have one dimension that is 100 nanometers or smaller. There are many natural structures with a size of one or more nanometers. Nanotechnology could have a big effect on society and help people in many ways. Using nanomaterials could lead to the discovery of new ways to reduce pollution. On the other hand, these compounds could pose risks to human health that we don’t know about yet. As long as the nanoparticles are attached to the carrier, there is no reason to think that they pose a greater risk to human health or the environment than materials that are bigger. Nanotechnology is different from other fields of technology because it can control things on a scale that is nanoscale. Nanotechnology has the potential to have a huge effect on society. Nanotechnology creates new materials that can do things at the nanoscale that no other materials can.
The industries most open to nanotechnology are those that deal with information and communications, such as electronics and optoelectronics. People should be concerned about what happens to free nanoparticles that are made by nanotechnology and then released into the environment. Because of their size, shape, or make-up, these nanoparticles could be harmful to people. This is because they have properties that have never been seen before. If there is a chance that a completely new danger will be found, it is very important to look into the nature of the risk in great detail.
