摘要

Semiconductor nanocrystals, also called quantum dots (QDs), are versatile inorganic probes with unique photo-physical properties, such as narrow and size-dependent fluorescence (FL) with broad absorption spectra, strong FL intensity and excellent anti-photo bleaching. QDs have been used in a diverse range of biological applications in different domains such as cell labeling, genomic detection, optical sensors, nanosensors, quantum mechanics based Drug Delivery systems and bio-medical imaging. Nanotechnology has the potential to revolutionize medicine, as well as many other seemingly unrelated subjects such as electronics, textiles and energy production.
