Quantum Dots, Synthesis Properties and Biology Application



Quantum Dots, Synthesis Properties and Biology Application

Nimai Mishra

Quantum dots (QDs) are semiconductor nanocrystals which show extraordinary optical and electrical properties due to quantum confined nature of their energy levels. For a given material, the variation in optical properties of the QD stem from its size. Typically, the size ranges from a few nanometers to tens of nanometers. Such small dimensions are usually smaller than the de- Broglie wavelength of thermal electrons. Due to quantum confinement effect these particles exhibit unique optical properties, such as narrow FWHM, high quantum yield, size dependent emission etc. which make them useful for the several biological applications such in bio-imaging and diagnosis. In this chapter, we describe the synthesis of different QDs, their functionalization, processing and their combination with suitable materials to match the needs of biological applications.
