Luminescent semi-conductor quantum dots (QDs) are an excellent class of nano-structured materials. As compared with conventional fluoreophores, QDs have a number of advantages, for example, stronger, narrower and more symmetrical fluorescence emission, excellent photostability, and size-tunable colors. A series of different-colored QDs can be activated by using a single laser source. Researchers have reported immense potential uses of QDs in optoelectronic and biological applications. In the last decades, most studies on QDs have focused on its ultra-sensitive biological detection, as well as a host of other bio-applications such as gene expression studies, highthroughput screening, and medical diagnostics based on optical coding technology.
