Nanotechnology: Reflections on Health Benefits and Risks

Abstract

There is a constant increase in the demand for engineers who can transform nanotechnology from a scientific result into a commercial solution. However, new technologies often caused conflicts between those who want to exploit them as soon as possible and those who are waiting to receive absolute proof of safety. Certain types of nanoparticles are well studied and recommended for use in medicine, biology, chemistry, cosmetology, etc. Some nanoparticles are proven to be extremely toxic, with drastically different properties from the same volume compounds. The risks associated with using nanotechnologies and products containing nanoparticles cannot be minimized in the absence of regulations, which would allow adequate control to protect the environment and the population’s health. Companies are also extremely careful in investing in this field as long as there is no transparent regulation, as the ultimate goal is to protect the surrounding environment and society. In this paper, we present an overview of the benefits of nanotechnology in areas that affect human health, as well as the risks that may arise from the early use or ill-will of nanotechnologies.
