Performing real-time tracking and imaging at molecular and cellular levels, Quantum Dots (QDs) offer highly sensitive results due to their nanometric, semiconductive, and optoelectronic properties.

Semiconductor nanoparticles with special optoelectronic properties which allow for real-time and highly sensitive tracking and imaging at molecular and cellular levels. New generations of QDs have been used to study intramolecular processes at a single-molecule level with high-resolution cellular imaging and long-term in vivo observation. By using UV-light or locally enhanced electromagnetic fields, it is possible to observe the photoluminescent change in the target in real-time or for high-resolution three-dimensional reconstructed imaging using adequate microscopes. QDs are much smaller in size and have been estimated to be 20 times brighter and 100 times more photostable than traditional fluorescent trackers.
