Background & Objective: Semiconductor quantum dots proved themselves as efficient
fluorescent probes in cancer detection and treatment. Their size, high stability, non-photobleaching
and water solubility made them a unique fluorophore in place of conventional organic dyes.
Method: Newly emerged theranostic drug delivery system using quantum dots helped us in better understanding
of the drug delivery mechanism inside the cells. Surface modified Quantum dots and their
applications became wide in bioimaging, immunohistochemistry, tracking intracellular drug and intracellular
Conclusion: We have highlighted various applications of quantum dots in cancer treatment, drug delivery,
flow cytometry, and theranostics.
