Abstract

Semiconductor quantum dots (QDs) are robust and bright light emitters that have captured special interest in biology and medicine due to their superior optical features. This paper is a study of the fluorescent properties of QDs and their role as fluorescent probes for various biological applications. The bioimaging applications, with reference to the study of microorganisms, are discussed. QDs are rapidly being employed for a series of existing and emerging technological applications, but our study deals with their capacity of microorganism labeling..
