“…For liquid‐phase CL, the water solubility (or rather, water dispersibility) of the reactant has an important influence on luminescence efficiency. Modification of QDs has greatly enhanced the CL of QDs−oxidant CL systems . Li and colleagues prepared water‐soluble CdS QDs capped with mercaptoacetic acid (MA) that could be directly oxidized by hydrogen peroxide under basic conditions to generate strong CL emission.…”

“…The CL of CdS QDs was also size dependent. Glutathione (GSH)‐modified CdTe QDs also displayed CL emission when reacted with H 2 O 2 in alkaline medium . CL was strongly enhanced after addition of formaldehyde in aqueous solution and there was good linearity between CL intensity and formaldehyde concentration over the 0.06–3.0 μg L −1 range.…”

This mini-review describes the recent developments in quantum dots-based nanoprobes in liquid-phase chemiluminescence (CL) analysis. In the referenced reports, multiple quantum dots (QDs) were adopted as final emission species either after direct oxidation reactions (direct CL) or after chemiluminescence resonance energy transfer (indirect CL). This review does not include papers in which QDs have been used as enhancers, catalysts, carriers or quenchers in chemiluminescence systems. A brief overview on the CL mechanisms of various QDs-based nanoprobes and their analytical applications over the last decade is given, followed by comments on the future challenges and prospects in this field.

“…Quantum dots (QDs) were used as an acceptor of CRET process due to their unique properties such as wide excitation, narrow emission, high quantum yield, size-dependent character and resistance to chemical and photo degradation [115][116][117]. At first time, Huang et al observed the CRET phenomenon between luminol as donor and CdTe QDs as an acceptor [118].…”

Quantum dots (QDs) have received great attention for development of novel fluorescent nanoprobe with tunable colors towards the near-infrared (NIR) region because of their unique optical and electronic properties such as luminescence characteristics, wide range, continuous absorption spectra and narrow emission spectra with high light stability. Quantum dots are promising materials for biosensing and single molecular bio-imaging application due to their excellent photophysical properties such as strong brightness and resistance to photobleaching. However, the use of quantum dots in biomedical applications is limited due to their toxicity. Recently, the development of novel and safe alternative method, the biomediated greener approach is one of the best aspects for synthesis of quantum dots. In this Chapter, biomediated synthesis of quantum dots by living organisms and biomimetic systems were highlighted. Quantum dots based fluorescent probes utilizing resonance energy transfer (RET), especially Förster resonance energy transfer (FRET), bioluminescence resonance energy transfer (BRET) and chemiluminescence resonance energy transfer (CRET) to probe biological phenomena were discussed. In addition, quantum dot nanocomposites are promising ultrasensitive bioimaging probe for in vivo multicolor, multimodal, multiplex and NIR deep tissue imaging. Finally, this chapter provides a conclusion with future perspectives of this field.
