Quantum Dots for Assessment of Reactive Oxygen Species Accumulation During Chemotherapy and Radiotherapy

Abstract

Quantum dots (QDs) are semiconductor nanoparticles ranging in size from 2 to 10 nm. QDs are increasingly being developed for biomedical imaging, targeted drug delivery, and green energy technology. Here we describe the novel utilization of biocompatible CdSe–ZnS core–shell semiconductor nanoparticles for assessment of reactive oxygen species (ROS) in the context of chemotherapy and radiotherapy, both of which are important modalities in the treatment of cancer.
