“…Therefore, the determination of the TPA concentration in water is significant for human health and environmental protection. 43 It is necessary to note that most of traditional ECL assays need high concentrations of TPA (usually up to 100 mM) to obtain good sensitivity, 40,42 while the cloth-based C-WL-ECL assays involve relatively lower concentrations of TPA (Fig. 5(D)).…”

The rising need for low-cost diagnostic devices has led to the search for inexpensive matrices that allow performing alternative analytical assays. Cloth is a viable material for the development of analytical devices due to its low material and manufacture costs, ability to wick assay fluids by capillary forces, and potential for patterning multiplexed channel geometries. In this paper, we describe the construction of low-cost, ultraflexible microfluidic cloth-based analytical devices (μCADs) for wireless electrochemiluminescence based on closed bipolar electrodes (C-WL-ECL), employing extremely cheap materials and a manufacturing process. The C-WL-ECL μCADs are built with wax-screen-printed cloth channels and carbon ink screen-printed electrodes, and the estimated cost per device is only $0.015. To demonstrate the performance of C-WL-ECL μCADs, the two most commonly used ECL systems - tris(2,2'-bipyridyl)ruthenium(ii)/tri-n-propylamine (Ru(bpy)3(2+)/TPA) and 3-aminophthalhydrazide/hydrogen peroxide (luminol/H2O2) - are applied. Under optimized conditions, the C-WL-ECL method has successfully fulfilled the quantitative determination of TPA with a detection limit of 0.085 mM. In addition, on the bent μCADs (bending angle (θ) = 180°), the luminol/H2O2-based ECL system can detect H2O2 as low as 0.024 mM. Based on such an ECL system, the bent μCADs are further used for determination of glucose in a phosphate buffer solution (PBS), with the detection limit of 0.195 mM. Finally, the applicability and validity, anti-interference ability, and storage stability of the C-WL-ECL μCADs are investigated. The results indicate that the proposed device has shown potential to extend the use of microfluidic analytical devices, due to its simplicity, low cost, ultraflexibility, and acceptable analytical performance.

“…Those nanomaterials with outstanding quantum efficiencies can be directly fabricated and employed as promising ECL emitters for signal transduction or image probing. For those nanomaterials with large specific surface areas or porous nanostructures, such as mesoporous silica nanospheres (MSNs) [10][11][12][13], multiwall carbon nanotubes [14][15][16], graphene oxide [17][18][19][20], Ti 3 C 2 MXene [21][22][23], and Au nanoparticles (NPs) [24], they can be utilized as the carriers to stabilize luminophores and developed as ECL emitters for biosensors. Unlike self-annihilation ECL pathway, a proper coreactant reagent is essentially required for coreactant ECL since it can generate abundant electro-active intermediates to promote the production of excited states, thus achieving stronger ECL intensity [25][26][27].…”

Electrochemiluminescence (ECL) is a light-emitting process triggered by the high energy redox between electrochemically oxidized and reduced luminophores or some coreactive intermediate radicals, representing a blooming hot topic over decades with a wide variety of bioanalytical applications. Due to the superb sensitivity, ultralow background noise, specificity, ease of integration, and real-time and in situ analysis, ECL has been developed as a convenient and versatile technique for immunodiagnostics, nucleic acid analysis, and bioimaging. Discovering highly-efficient ECL emitters has been a promising subject that will benefit the development of sensitive bioanalytical methods with prominent potential prospects. To date, the interdisciplinary integrations of electrochemistry, spectroscopy, and nanoscience have brought up the continuous emergences of novel nanomaterials which can be flexibly conjugated with specific bio-recognition elements as functional ECL emitters for bioassays. Therefore, a critical overview of recent advances in developing highly-efficient ECL emitters for ultrasensitive detection of protein biomarkers is presented in this review, where six kinds of the most promising ECL nanomaterials for biosensing and imaging of various disease-related protein biomarkers are separately introduced with references to representative works. Finally, this review discusses the ongoing opportunities and challenges of ECL emitters in developing advanced bioassays for single-molecule analysis and spatiotemporally resolved imaging of protein biomarkers with future perspectives.

Detecting hydrogen peroxide (H 2 O 2 ) is obviously indispensable on account of its low toxicity and wide application, and it is still a challenge for developing highly sensitive and selective electrochemiluminescence (ECL) sensors based on the noble metal-free electrode. Hence, we designed an accurate ECL sensor for detecting trace H 2 O 2 based on N-doped porous carbon containing Fe (Fe/N-C) nanocomposites, which were successfully synthesized by pyrolysis of NH 2 -MIL-101(Fe) metal-organic framework (MOF). Fe/N-C nanocomposite significantly improved the electron transfer process and enhanced the catalytic activity of ECL sensor for trace H 2 O 2 detection. Fe/N-C nanocomposite significantly contributed in the conversion of H 2 O 2 to superoxide radical, followed by the oxidation of luminal which enhanced the electrochemical luminescence signal. Predictably, the ECL sensing strategy at Fe/N-C nanocomposite electrode showed a satisfying linear range from 1 nM to 300 nM for H 2 O 2 detection with limit of detection (LOD) as 0.93 nM (signal to noise ratio (S/N) = 3). Also, the ECL sensor was used to detect H 2 O 2 in real water samples and renal epithelial 293T cells, which justified great promise for the practical ECL detection of H 2 O 2 .
