QUANTUM DOTS AS THE NEWSTREAM OF CANCER DIAGNOSIS

Materials at nano dimensions exhibit totally different properties compared to their bulk and atomic states. We describe the development of multifunctional nanoparticle probes based on semiconductor quantum dots (QDs) for cancer targeting and imaging in living animals. This feature has been harnessed by scientists from various disciplines, to develop cancer diagnosis and therapeutics. This brief review summarizes the recent developments of various nanotechnologies in cancer therapy and diagnostics, both from the research sector and the upcoming products in pipeline on its route to commercialization. Supportive engineering innovations and frontiers in nanomolecular research, with a potential to revolutionize cancer diagnosis and therapy, have been discussed in brief.
