“…It has been extensively used as an ECL luminophore due to its high quantum efficiency, excellent luminescence properties, good reproducibility, and high sensitivity. However, (Ru(bpy) 3 2 + produces strong background light in alkaline environments, [69] so some studies utilized its derivatives as luminophores in ECL systems for metal detection, such as [Ru(bpy) 2 (phen-ABAH)]Cl 2 , [70] [Ru-(phen) 2 dppz] 2 + , [71] [Ru(bpy) 2 (dppz)](BF 4 ), [72] Ru(bpy) 2 (dcbpy)-NHS-DNA2, [73] Ru(bpy) 2 (dcbpy), [74] Ru(bpy) 2 (mcbpy)-NHS, [75] Ru-(dcbpy) 3 2 +…”

“…In addition to PAMAM, NGQDs and CNQDs have been developed as co-reactants to produce self-enhanced ECL luminophores. NGQDs were combined with Ru(bpy) 3 2 + -doped silica nanoparticles (NH 2 -Ru@SiO 2 NPs) via electrostatic adsorption. [84] For aptasensor construction, GCE was modified with AuNPs via the electrodeposition technique.…”

“…These probes created a double-stranded structure in the presence of Hg(II) collected on the electrode surface by highly condensed using a magnetic field, so the high ECL signal of Ru(bpy) 3 2 + can be detected. Combining Ru(bpy) 3 2 + and other luminophores was also performed to improve metal analysis in ECL systems. Moghaddam et al developed a bipolar electrochemiluminescence (BP-ECL) system using two luminophores Ir(ppy) 3 and Ru(bpy) 3 2 + for copper and cadmium detection.…”

Moghaddam et al developed a bipolar electrochemiluminescence (BP-ECL) system using two luminophores Ir(ppy) 3 and Ru(bpy) 3 2 + for copper and cadmium detection.

“…On the other hand, Ru(bpy) 3 2 + , serving as the acceptor of the electrochemiluminescence -resonance energy transfer (ECL-RET) system, was excited to form Ru(bpy) 3 2 + *, which returns to the ground state with light emission under the energy absorption of Au-g-C 3 N 4 . Furthermore, Peng et al studied an ECL-RET system between carbon nitride nanofibers (CNNFs) and Ru(phen) 3 2 + for ultrasensitive Pb(II) detection. [100] Upon specific hybridization between capture DNA and Pb(II)-specific aptamer, Ru(phen) 3 2 + was collected onto the CNNF-modified electrode by effectively intercalating into the double-stranded DNA groove, thus triggering ECL-RET and resulting in a high ECL intensity enhancement.…”

Electrogenerated chemiluminescence or electrochemiluminescence (ECL) is a chemiluminescence phenomenon generated by electrochemical reactions. Applying this phenomenon for metal ions detections is potentially effectual as it provides excellent selectivity and sensitivity as well as the ease of use and economical cost. Accordingly, the detection methods of many trace metals have been successfully developed by employing ECL systems, including Hg(II), Pb(II), Cu(II), Cd(II), Fe(III), Ag(I), Co(II), Cr(III), Cr(VI), Ni(II), and As(III). There are several key components required to comprise the ECL systems, including luminophores that emit light and are directly proportionate toward metal concentrations, co‐reactants that increase the number of excited luminophores, and electrodes where the electron transfer occurs. Some new ECL systems comprising luminophores, co‐reactants, and electrodes have been developed to achieve impressive measurement results with low detection limits. This paper aims to provide a comprehensive illustration concerning the development of ECL‐based metal sensors, to elucidate a development overview of key elements employed in ECL systems and their modifications, explaining the different types of interactions due to the presence of metal ions in ECL systems, as well as to discuss the future opportunities and challenges of the ECL systems.

Surabaya’s coasts, situated in an active metropolitan region, threatened by metal contamination, which can be found in particulate matter. However, data of suspended particulate matter (SPM) and particulate metals on the Surabaya Coast are scarce. This study aims to systematically evaluate the impact of trace metals on the environment through particulate metal analysis. Water sample was taken in May 2017 at 17 sites, and analyzed using the acid digestion procedure and measured by ICP-MS. The results show that SPM levels range from 10.80 – 51.80 mg/L, while the concentrations of particulate metals range from 0 – 2.78 mg/kg, 1.14 – 130.77 mg/kg, 3.43 – 60.19 mg/kg and 0.87 – 7.00 mg/kg dry weight for Cd, Cu, Pb, and As, respectively. The location of Surabaya coast might affects salinity and temperature where eastern part is more affected by Madura Strait, but metal concentration are all affected by riverine input. Based on the Geo-accumulation Index and Pollution Load Index, several sites on the Surabaya’s coasts are polluted. However, they have low-level toxicity and insignificant mortality, indicating the Surabaya Coast environments is still safe for living habitat. Meanwhile, particulate metal concentrations are relatively high in several locations, possibly caused by the port, marine tourism, and other anthropogenic activities.
