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. KEYWORDS chemiluminescence (CL), nanoprobe, quantum dots (QDs)

“…15 Nowadays, nanomaterials are widely used as nanoprobes, sensors or signal amplifier by many analysts. [16][17][18][19][20][21][22] Particularly, carbon nanotubes (CNTs) with new functional groups are ideal candidates for signal amplification due to their large surface area and the ability to integrate with biological elements. As a carrier, the CNTs were used to incorporate biomolecules (such as enzymes, antibodies, etc.)…”

The extensive use of polybrominated diphenyl ethers (PBDEs) has resulted in its increasingly widespread presence. Especially the lower halogenated PBDEs accumulate to a greater degree than the higher halogenated PBDEs in house dust, sewage sludge, pets, or even humans. In the present work, we developed an ultrasensitive biotin-streptavidinenhanced carbon nanotube amplification strategy for the immunodetection of PBDEs, in which single-walled carbon nanotubes were used to immobilize numerous streptavidin. Meanwhile, we used biotin conjugated horseradish peroxidase (B-HRP) and biotin conjugated Goat anti-rabbit (B-IgG) to link the HRP and IgG to CNTs by using a biotin-streptavidin system. The sensitivity of the streptavidin-biotin-IgG-CNTs-HRP bioconjugate was compared with a commercial HRPlabelled IgG by using indirect competitive ELISA. The limit of this proposed ELISA detection (IC10) was 0.0059 ng/mL, showing a 20-time lower detection limit over the commercial one (IC10 = 0.1193 ng/mL). Finally, we applied the assay to the detection of PBDEs in dust samples. The results were consistent with those using GC-ECD, which confirmed that the proposed amplification strategy was accurate and receptive. This proposed biotin-streptavidin-enhanced carbon nanotube amplification strategy would be useful for ultrasensitive immunodetection in environmental studies.

“…Chemiluminescence (CL) [11][12][13] has the advantages of fast speed, simple instrumentation, wide linear range and high sensitivity. [14][15] Therefore, CL analysis has been widely used in diverse fields including biology, food analysis, 16 pharmacology 17 and clinical assays. 18 In recent years, CL has been used for the detection of PCs and the evaluation of antioxidant capacity.…”

In this work, a new chemiluminescence (CL) system of Co-Fe prussian blue analogs nanocubes (Co-Fe PBA NCs) which can catalyze luminol to produce strong CL in the absence of H2O2 was established. Co-Fe PBA NCs has the property of oxidase-like activity and it can catalyze the generation of active oxygen radicals in the dissolved oxygen system. Since caffeic acid (CA) can remove reactive oxygen species in the system, a sensitive detection method for CA on the paper-based chip was developed.Under the optimal conditions, the method showed good linear response to CA in the range of 10 ng/mL-800 ng/mL with the limit of 3 ng/mL. The proposed method had been used for the determination of CA in tea samples. The results may open a new avenue for the catalytic property on luminol CL system without extra oxidants.
