Nanotechnology is the use of materials that are one-billionth of a metre (a nanometre) in size. One of its potential uses is to clean up whatever is contaminating water supplies. Analytical chemist Philiswa Nomngongo, a leading researcher in nanotechnology for water in South Africa, tells The Conversation Africa what kinds of devices are being produced with nanotechnology and what they can do.
What is nanotechnology?
Nanotechnology is the branch of science and engineering that is devoted to designing new materials or devices that have unique physical and chemical properties because of their tiny size. It involves manipulating atoms and molecules at nanoscale.
