Abstract

QDs are semiconductor nanocrystalline materials with distinct optical and electronic characteristics due to their microscopic size and quantum mechanical properties. They are often composed of materials such as cadmium selenide (CdSe), cadmium telluride (CdTe), or indium phosphide (InP) and are typically in the size range of 2 to 10 nanometers in diameter. These tiny particles are used in various scientific and technological applications. Some key characteristics and applications of quantum dots are size-dependent Optical Properties with tunable emission. The color of light emitted by quantum dots highly depends on their size. Smaller QDs emit blue or green light, while larger ones emit red or near-infrared light. This tunability makes them valuable in various applications, especially in molecular medicine and oncology research. Quantum dots can exhibit a high quantum yield, meaning they efficiently emit light when excited, making them excellent fluorescent probes for non-invasive imaging. This review discusses the applications of QDs and their role in biomedical research and patient care, focusing on non-invasive imaging and preventive oncology.

Keywords: Drug Delivery; Quantum dots; fluorescent imaging; preventive oncology; sensors.
