Quantum Dots Nanocomposites as Drug Delivery Vehicle

Quantum dots nanocomposites (QDNCs) has triggered enormous interest in, its applications in various fields of medicine and pharmaceutical science due to its unique properties. While QDNCs has demonstrated suitable potential as an imaging probe in medical imaging, its application as a nano-vehicle in drug delivery system for drugs and biomolecules in biomedicine, has only begun to be consideration. Advanced nano-carriers with slow, controllable release and excellent carrier efficiency are now considered the ideal vehicle for developing drug delivery systems. Remarkable properties of QDNCs include chemical stability, extremely large surface area, and low toxicity making it a promising material to design of novel drug delivery systems. Recent research has demonstrated significant success in the use of QDNCs for medical applications, including its utilization as a vehicle for controlled drug delivery, as well as in photothermal therapy, photodynamic therapy, and theranostic application. This chapter, presents a comprehensive overview of the current studies of drug delivery systems based on QDNCs vehicle. Moreover, various strategies for nano-vehicle design, functionalization methods for effective drug delivery, and reduction of quantum dots toxicity and the essential features for design of new Quantum dots nanocomposites vehicle in photothermal therapy, photodynamic therapy, and controlled drug delivery presented.
