Quantum Dots are the newest member of the Advance Materials sector. Small, microscopic sized particles that have the most interesting phenomenon of fluorescing when exposed to UV light!! By changing the size of the quantum dot, we can change the colors that they fluoresce.
Quantum dots produced today are based on Inorganics, usually metals, which although giving them excellent fluorescent attributes, are also very toxic, therefore limiting their use in many applications.

Current day market applications of Quantum Dots (QD) rely on metallic based inorganic QDs, that have numerous potential in optoelectronic devices, such as emitters for color displays, color modifiers for light emitting diodes (LEDs), optical fiber amplifiers, polymer-based photovoltaic cells. One of the most famous and frequent uses of QDs are in televisions (see Samsung’s new HDQDTV). Additional applications include: optical temperature probes, chemical sensors, high-speed signal-processing filters and more. Conjugation of QDs with antibodies yields biomarkers that compete with traditional organic fluorescent tags in terms of biocompatibility, excitation and filtering simplicity, and photo-stability. In bio-imaging QDs can be used to target cancer cells, tumors and other bio imaging anomalies.
