Hsu Zi-Bo Li Xiaoyuan Chen Received 14 April 2007 Accepted 24 April 2007 Published online 30 May 2007 to the authors 2007 Abstract Nanotechnology has the potential to profoundly transform the nature of cancer diagnosis and cancer patient management in the future. Over the past decade quantum dots QDs have become one of the fastest growing areas of research in nanotechnology. QDs are fluorescent semiconductor nanoparticles suitable for multiplexed in vitro and in vivo imaging. Numerous studies on QDs have resulted in major advancements in QD surface modification coating biocompatibility sensitivity multiplexing targeting specificity as well as important findings regarding toxicity and applicability. For in vitro applications QDs can be used in place of traditional organic fluorescent dyes in virtually any system outperforming organic dyes in the majority of cases. In vivo targeted tumor imaging with biocompatible QDs has recently become possible in mouse models. With new advances in QD technology such as bioluminescence resonance energy transfer synthesis of smaller size non-Cd based QDs improved surface coating and conjugation and multifunctional probes for multimodality imaging it is likely that human applications of QDs will soon be possible in a clinical setting.
