Bright Semiconductor Quantum Dots Shed New Light on Precision Nanomedicine for Various Diseases.

Nanomaterials with diagnostic and therapeutic functions have exciting potential to reshape the landscape of precision medicine. Impressive progress has been made toward the design and production of innovative theranostic nanomaterials that improve disease care, motivated by their ability to simultaneously provide diagnostic information and therapeutic benefits. Herein, the state‐of‐the‐art theranostic semiconductor quantum dots (QDs) are summarized, and the diverse types of QDs designed for the diagnosis and treatment of different diseases are discussed. The opportunities and benefits of QDs are highlighted throughout using in vitro and in vivo examples aimed at addressing various clinical challenges, including cancer, vascular dysfunctions, microbial infections, and medical tattoos. Over the past several years, this area has experienced enormous growth, particularly in preclinical animal imaging and therapy, which has brought the field closer to reaching human patients. Unfortunately, several barriers to clinical translation remain. Therefore, in addition to summarizing the key results from previous in vivo studies, the lessons learned from these studies are synthesized, perspective on the future steps needed for both fundamental studies and the clinical translation of theranostic QD nanotechnology to inform future QD design is provided.
