Bifunctional TiO2 Nanoflower-Induced H4TCBPE Aggregation Enhanced Electrochemiluminescence for an Ultrasensitive Assay of Organophosphorus

“…When H 4 TCBPE was grown on TiO 2 , it was observed that the diameter of the nanoparticle was increased and the spaces of the petals were filled with tulle-like material (Figure 1B,C). Following that, X-ray photoelectron spectroscopy (XPS) and energy-dispersive spectroscopy (EDS) were employed to demonstrate the chemical elements and their binding states of the H 25,32,43 In the high-resolution spectra of Ti 2p (Figure 2D), two peaks situated at 458.7 and 464.4 eV belong to Ti 2p 3/2 and Ti 2p 1/2 , respectively. It shows that the Ti species in H 4 TCBPE-TiO 2 nanospheres were Ti 4+ , which can coordinate with carbonyl oxygen.…”

“…According to previous reports, TiO 2 nanoflowers could be employed as an immobilization matrix to immobilize the PAHs molecules for the synthesis of high-performance ECL emitters. 32 , which resulted in the enhancement of the ECL intensity. 33 From this foundation, a novel ECL emitter, H 4 TCBPE-TiO 2 nanosphere, was designed in this work.…”

A metal–organic framework regulated graphdiyne-based electrochemiluminescence sensor with a electrocatalytic self-acceleration effect for the detection of di-(2-ethylhexyl) phthalate

“…19 Organic dyes, quantum dots, and gold nanoclusters represent the prominent examples of commonly employed luminescent materials within this context. [20][21][22][23][24] Nonetheless, the practical applications of these materials are limited by the inherent fragility of organic dyes in terms of optical stability, 25 the occurrence of light leakage in quantum dots, and the instability displayed by metal clusters. Therefore, there arises a significant imperative to investigate luminous entities that exhibit exceptional attributes pertaining to light stability, sensitivity, and biocompatibility.…”

Programmable Y-Shaped Probes with Proximity Bivalent Recognition for Rapid Electrochemiluminescence Response of Acute Myocardial Infarction

“…Electrochemiluminescence (ECL), combined with the advantages of electrochemistry and luminescence analysis, has become one of the most important bioanalytical methods in vitro with its high sensitivity, low background, , and high controllability. − Conventionally, the S 2 O 8 2– is one of the most widely used coreaction reagents in most cathode ECL process, such as ruthenium complexes, , polycyclic aromatic hydrocarbons, and quantum dots, − because it has the characteristics of chemical stability and moderate electrochemical reactivity. Recent research demonstrated the ECL signal could also be generated from excited mode of singlet oxygen ( 1 (O 2 ) 2 *) in S 2 O 8 2– solution, which is produced by the free radical reaction of reactive oxide species (ROS) and SO 4 •– from electrochemical reduction process of dissolved oxygen (DO) and S 2 O 8 2– , respectively.…”
