While nanotechnology is popular overseas, in South Africa it is still in its infancy. Many South African universities and scientific institutions are now doing research and development in this field. The scope and application of nanotechnology is overwhelming. It is one of the most diverse fields and the hottest topic for many scientists and engineers. The interdisciplinary nature of nanoscience and nanotechnology allows for study in many fields, such as chemistry, biology, physics, engineering, environmental science, agriculture, medicine, law, business, pharmacy, social science, e.g. ethics, etc. This has resulted in the opening of job opportunities worldwide.
