Abstract :
Biotechnology reported the successful development of a self-illuminating type of quantum dot that can reveal its presence without the need for an external light source. In this article, we describe the major techniques for producing quantum dots and applications of the two classes of quantum dots (colloidal and epitaxial) in imaging.
