Future prospects and concluding remarks of quantum dots

Quantum dots (QDs) have emerged as a promising class of nanomaterials, revolutionising the field of nanomedicine, particularly in drug delivery systems. Their unique properties, such as tunable fluorescence, high photostability, and size-dependent optical characteristics, provide distinct advantages over conventional drug delivery platforms. QDs have shown potential in targeting specific tissues, enhancing bioavailability, and enabling real-time tracking of therapeutic agents in various biomedical applications, including oncology, neurological disorders, gene therapy, and infectious diseases. Recent advancements in QD synthesis, surface functionalisation, and stimuli-responsive designs have further expanded their utility, making them versatile tools in precision medicine. However, challenges remain in ensuring biocompatibility, safety, and regulatory approval of QD-based therapies. As research progresses, innovations such as bioengineered QDs, integration with artificial intelligence, and their role in regenerative medicine hold significant promise for future clinical applications. This chapter explores the current status, recent innovations, emerging applications, and future perspectives of QDs in drug delivery, shedding light on their potential to transform therapeutic strategies in the years to come.
