NANOTECHNOLOGY: PROSPECTS AND CHALLENGES

Abstract

Nanotechnology emerges from the classic talk entitled “There’s plenty of Room at the Bottom” and has got
shape as a new field of research after the invention of scanning tunneling microscope (STM) and atomic
force microscope (AFM). Finally, the discovery of fullerenes and inventing Carbon Nanotube Tube (CNT) in
1990 became the launching pad of Nanotechnology. Fundamental concerns, synthesizing and characterization
technique have been discussed for understanding Nanotechnology in this review article. After 30 years of the
birth of this technology, manufactured Nano-products have reached to around 3500 and become available
for public usage. Worldwide scientists are pursuing for synthesizing nanomaterials with various objectives in
almost all encompassed fields of science, engineering and technologies. As such, the scope of applications of
Nanotechnology is becoming wider, and leading it to be more prospective. But in the meantime, some issues on
the usage of Nano-products have been surfaced those are to be mitigated and thereby scientist, engineers and
technologists would have to face as challenges in the near future. All these prospects and issues are discussed
briefly in this review article for the purpose.
