Aptamer-Conjugated Quantum Dot Optical Biosensors: Strategies and Applications

Quantum dots (QDs) represent the promising new generation of luminophores owing to their size-, composition-, and surface-dependent tunable photoluminescence (PL) and photochemical stability. The development of various QD composites with high PL and good biocompatibility has facilitated the use of a...
