(2510)REVIEW OF VARIOUS NANOMATERIALS AND THEIR MAJOR HEALTH ISSUES

摘要

Various nanomaterials, including nanoparticles, nanowires, nanotubes, nanofibers, nanocomposites and nanofilms have been produced for over two decades and used for many industrial applications, such as automobile, aircraft, energy, medical, defense, electronics and telecommunications, health care, sensor and textile. These nanoscale materials have outstanding mechanical, magnetic, electrical, optical and thermal properties compared to their bulk size counterparts. More than 1300 nanoproducts are currently in the market, and this number will apparently reach to 5000 very soon. The recent studies show that these nanomaterials can enter the body by inhalation, ingestion and dermal contacts and can damage or kill the cells or organs, block blood flow, and also cause serious illnesses. Some of the diseases associated with nanomaterials include asthma, bronchitis, lung and liver cancer. In the present study, we will discuss about the exposures of nanomaterials to the human body, their major health issues, prevention methods, and recent development in the field.
