QUANTUM DOT FLUORESCENT NANOPARTICLES
Quantum dots (QD) are semiconductor nanocrystals several nanometers in diameter. When excited by light or electrical current, QDs emit light of specific frequencies (or colours) which enable them to be used as detectors in biological systems. Ellume scientists have developed techniques to form a novel class of particle based on hundreds of quantum dots which is used as an ultra-bright fluorescent reporter in Ellume products. This reporter, when bound with detector antibodies, delivers substantial improvements in performance when compared to existing detectors.
