Abstract
Background: Nanotechnology is an emerging field that could have a significant impact on cancer diagnosis, treatment and analysis. Quantum dots represent one of the most interesting nanotechnology-based platforms, and their unique properties make them a potentially versatile tool for molecular diagnostics. Objectives: Here, the most promising uses of quantum dots for translational research are reviewed, ranging from multiplexed immunofluorescence, targeted drug delivery coupled with disease visualization, tumor and sentinel organs localization and long-term cell tracing. Finally, potential future directions for quantum dots as both a diagnostic and therapeutic tool in biomedical research will be explored. Conclusions: The use of quantum dots in biomedical applications is accelerating owing to their unique physical attributes, imaging capabilities, and potential for therapeutic delivery.
