Electroanalytical applications of quantum dot-based biosensors /

Quantum dots (QDs) are hybrid organic/inorganic nanoparticles with novel physical properties.QDs have two components: an inorganic core and an optically active coated shell.Moreover, surface coatings can be applied to QDs to modify the particle as needed for experiments.
