Abstract
A novel sandwich-type biosensor denoted as "MIP-analyte-Ab" was constructed on a glassy carbon electrode modified with gold nanoparticles (AuNPs@GCE), which is dedicated to explore a general solution for electrochemical tests in a relatively high potential range on Au electrodes. In particular, parasitic reactions of Au oxidation severely hindered the electrochemiluminescence (ECL) reactions of the Ru(bpy)32+/tripropylamine (TPrA) system. In this work, we designed an ultra-fast redox pulse to alleviate reversible oxidation of Au with a potential range of -0.5 to 0.9 V. Stable ECL signals were generated in the last 3 ms of each run (RSD = 5.86%), and interesting mechanisms were revealed. The ultra-high-frequency sampler indicated that free diffusion of TPrA•+ was the rate-determining step at 0.9 V, and it followed a totally different route with ECL at 1.3 V. Furthermore, we proposed a particular ECL reaction route at 0.9 V with C5 desosamine of the analyte, azithromycin, involved for the first time, based on results of radical identification. We believe that our work paved the way for the application of Au-based sandwich-type biosensors in environmental monitoring.

Abstract
Globally, 70 million people are annually affected by TBI. A significant proportion of all TBI cases are actually mild TBI (concussion, 70-85%), which is considerably more difficult to diagnose due to the absence of apparent symptoms. Current clinical practice of diagnosing mTBI largely resides on the patients' history, clinical aspects, and CT and MRI neuroimaging observations. The latter methods are costly, time-consuming, and not amenable for decentralized or accident site measurements. As an alternative (and/or complementary), mTBI diagnostics can be performed by detection of mTBI biomarkers from patients' blood. Herein, we proposed two strategies for the detection of three mTBI-relevant biomarkers (GFAP, h-FABP, and S100β), in standard solutions and in human serum samples by using an electrochemiluminescence (ECL) immunoassay on (i) a commercial ECL platform in 96-well plate format, and (ii) a "POC-friendly" platform with disposable screen-printed carbon electrodes (SPCE) and a portable ECL reader. We further demonstrated a proof-of-concept for integrating three individually developed mTBI assays ("singleplex") into a three-plex ("multiplex") assay on a single SPCE using a spatially resolved ECL approach. The presented methodology demonstrates feasibility and a first step towards the development of a rapid POC multiplex diagnostic system for the detection of a mTBI biomarker panel on a single SPCE.

Abstract
Abstract
Background
In this label-free bioassay, an electrochemiluminescence (ECL) immunosensor was developed for the quantification of breast cancer using HER-2 protein as a metastatic biomarker.
Method
For this purpose, the ECL emitter, [Ru(bpy)3]2+, was embedded into biocompatible chitosan (CS) polymer. The prepared bio-composite offered high ECL reading due to the depletion of human epidermal growth factor receptor 2 (HER-2) protein. Reduced graphene oxide (rGO) was used as substrate to increase signal stability and achieve greater sensitivity. For this, rGO was initially placed electrochemically on the glassy carbon electrode (GCE) surface by cyclic voltammetry (CV) technique. Next, the prepared CS/[Ru(bpy)3]2+ biopolymer solution was coated on a drop of the modified electrode such that the amine groups of CS and the carboxylic groups of rGO could covalently interact. Using EDC/NHS chemistry, monoclonal antibodies (Abs) of HER-2 were linked to CS/[Ru(bpy)3]2+/rGO/GCE via amide bonds between the carboxylic groups of Ab molecules and amine groups of CS. The electrochemical behavior of the electrode was studied using different electrochemical techniques such as electrochemical impedance spectroscopy (EIS), differential pulse voltammetry (DPV) and square wave voltammetry (SWV) and also ECL tests.
Results
After passing all optimization steps, the lower limit of detection (LLOQ) and linear dynamic range (LDR) of HER-2 protein were practically obtained as 1 fM and 1 fM to 1 nM, individually. Importantly, the within and between laboratory precisions were performed and the suitable relative standard deviations (RSDs) were recorded as 3.1 and 3.5%, respectively.
Conclusions
As a proof of concept, the designed immunosensor was desirably applied for the quantification of HER-2 protein in breast cancer suffering patients. As a result, the designed ECL-based immunosensor has the capability of being used as a conventional test method in biomedical laboratories for early detection of HER-2 protein in biological fluids.

Abstract
We examined a series of commercially available screen-printed electrodes (SPEs) for their suitability for electrochemical and electrogenerated chemiluminescence (ECL) detection systems. Using cyclic voltammetry with both a homogeneous solution-based and a heterogeneous bead-based ECL assay format, the most intense ECL signals were observed from unmodified carbon-based SPEs. Three commercially available varieties were tested, with Zensor outperforming DropSens and Kanichi in terms of sensitivity. The incorporation of nanomaterials in the electrode did not significantly enhance the ECL intensity under the conditions used in this evaluation (such as gold nanoparticles 19%, carbon nanotubes 45%, carbon nanofibers 21%, graphene 48%, and ordered mesoporous carbon 21% compared to the ECL intensity of unmodified Zensor carbon electrode). Platinum and gold SPEs exhibited poor relative ECL intensities (16% and 10%) when compared to carbonaceous materials, due to their high rates of surface oxide formation and inefficient oxidation of tri-n-propylamine (TPrA). However, the ECL signal at platinum electrodes can be increased ∼3-fold with the addition of a surfactant, which enhanced TPrA oxidation due to increasing the hydrophobicity of the electrode surface. Our results also demonstrate that each SPE should only be used once, as we observed a significant change in ECL intensity over repeated CV scans and SPEs cannot be mechanically polished to refresh the electrode surface.

Abstract
Although the clinical use of immunoassays based on the oxidative-reduction electrochemiluminescence (ECL) of tris(2,2'-bipyridine)ruthenium (II)/tri-n-propylamine has been a great success, elucidation of the ECL generation mechanism still remains unsatisfactory. We report here our experimental observations of long-lived luminescence that remains detectable for several seconds after termination of electrochemical heterogeneous oxidation. Long-lived luminescence was observed in both a surfactant-free buffer and a surfactant-containing broadly used commercial buffer under different conditions. The slow decay of emission seems to have been unnoticed in previous ECL mechanistic studies. Within the frame of the reaction schemes so far proposed, its origin is inconclusively ascribed to the reductive-oxidation process of ruthenium (II) complex, that is Ru(bpy)3 2+ → Ru(bpy)3 1+ → Ru(bpy)3 2+ * → Ru(bpy)3 2+ with the involvement of the tri-n-propylamine-derived radical cation. It is anticipated that long-lived ECL will suggest a research approach to separate some homogeneous reactions from the complicated reaction system and therefore help to resolve the mechanistic mystery.

Abstract
We present studies on ruthenium-based electrochemiluminescence (ECL) focusing on conditions supporting signal enhancement and low oxidation potentials. Low oxidation potentials (LOPs) are especially attractive for miniaturized ECL biosensors, as microfabricated electrodes tend to detach from their support when used with high currents and operated at high potentials. Furthermore, high potentials or current densities can lead to damage of typical biosensor surface coatings and biological probes. The possibility of generating LOP ECL signals at a potential below 900 mV was therefore studied for Ru(bpy)32+ with two typical coreactants, i.e. 2-(dibutylamino)ethanol (DBAE) and tripropylamine (TPA), as well as with the tertiary amine N-butyldiethanolamine (NBEA). Furthermore, the effect of buffer components and pH values on ECL signal generation was investigated. We could show a significant LOP ECL signal for NBEA. We found that Tris buffer, with its ability to form complexes with transition metal ions, has a positive influence on this ECL signal in terms of signal strength and LOP capabilities. Specifically, at basic pH values significant increases in ECL signals were observed at 900 mV and at 1.2 V. In fact, the ECL signal at 1.2 V was three times higher than the signal observed in phosphate buffer at a pH of 7, and it was thirty times higher than the ECL signal for TPA under these conditions. The LOP signal for NBEA in Tris buffer at pH 8.5 was similar to the signal obtained for TPA in phosphate buffer at pH 8.5 but three times higher than for TPA at pH 7.0. Interestingly, the coreactant DBAE was neither significantly influenced by the buffer system or pH nor did it present a valuable LOP ECL signal. Finally, it was found that high peak currents in cyclic voltammograms are not the indicators for high ECL signals, which should be obvious because the ECL mechanism requires more complex electron transfers. Overall, the standard TPA ECL at 1.2 V in phosphate buffer at pH 7.0 can successfully be replaced by NBEA ECL at 900 mV in Tris at pH 8.5 providing significantly higher signals accompanied by more gentle electrochemical conditions.

Abstract
An efficient aptasensor was developed in which graphene oxide (GO) was employed as an indicator for both electrochemical impedance spectroscopy and electrochemiluminescence (ECL) signal generation. The aptasensor was fabricated by self-assembling the ECL probe of a thiolated adenosine triphosphate binding aptamer (ABA) tagged with a Ru complex (Ru(bpy)3(2+) derivatives) onto the surface of gold nanoparticle (AuNP) modified glassy carbon electrode (GCE). ABA immobilized onto AuNP modified GCE could strongly adsorb GO due to the strong π-π interaction between ABA and graphene oxide; ECL quenching of the Ru complex then takes place because of energy transfer and electron transfer, and a large increase of the electron transfer resistance (Ret) of the electrode. While in the presence of target adenosine triphosphate (ATP), the ABA prefers to form ABA-ATP bioaffinity complexes, which have weak affinity to graphene oxide and keep the graphene oxide away from the electrode surface, thus allowing the ECL signal enhancement, and in conjunction with the decrease of the Ret. Because of the high ECL quenching efficiency, unique structure, and electronic properties of graphene oxide, the Ret and ECL intensity versus the logarithm of ATP concentration was linear in the wide range from 10 pM to 10 nM with an ultra-low detection limit of 6.7 pM to 4.8 pM, respectively. The proposed aptasensor exhibited excellent reproducibility, stability, and outstanding selectivity, and ATP could be effectively distinguished from its analogues. More significantly, this efficient ECL aptasensor strategy based on GO acting both as an electrochemical and ECL signal indicator is general and can be easily extended to other biological binding events.

Abstract
A carbon nanotube-based electrode that combines transparency and good conductivity was used for the first time to develop an electrochemiluminescence (ECL) device. It resulted in an excellent material for ECL applications thanks to the very favorable overpotential of amine oxidation that represents the rate-determining step for the signal generation in both research systems and commercial instrumentation. The use of carbon nanotubes resulted in a ten times higher emission efficiency compared with commercial transparent indium tin oxide (ITO) electrodes. Moreover, application of this material for proof-of-principle ECL imaging was demonstrated, in which micro-beads were used to mimic a real biological sample in order to prove the possibility of obtaining single cell visualization.

Abstract
Surface enhanced spectroscopy such as surface enhanced Raman spectrum (SERS) and surface enhanced fluorescence have been investigated extensively in the past two decades. Herein, we present experimental evidence to demonstrate the existence of a new surface enhanced spectroscopy, namely, surface enhanced electrochemiluminescence (SEECL). Our investigation indicates that the electrochemiluminescence (ECL) response of the Ru(bpy)32+-tri-n-propylamine (TPrA) system could be significantly enhanced when the working electrode is modified with gold nanoparticle-SiO2 core-shell nanocomposites (AuNP@SiO2). It is worth noting that comparing with a working electrode modified with pure SiO2 nanoparticles, the electrochemical responses of the two electrodes were quite similar, but the ECL signal of the AuNP@SiO2 modified electrode was ~5 times higher than that of the SiO2 nanoparticles modified electrode. Thus we infer that the localized surface plasmon resonance (LSPR) of the AuNPs could be a major contribution to the ECL enhancement. Our investigations also demonstrate that the ECL enhancement is closely related to the thickness of the SiO2 layer. As much as 10 times ECL enhancement (comparing with the ECL intensity of bare electrode) is observed under the optimal conditions. The possible mechanism of the SEECL phenomenon is also discussed.

Abstract
Vitamin C derivatives (VCDs) have been widely used as the alternative and stable sources of vitamin C, and accordingly exhibit many new applications, such as anti-tumor and central nervous system drug delivery. In this study, their Ru(bpy)(3)(2+) electrochemiluminescence (ECL) properties have been investigated for the first time using well-known ascorbyl phosphate and ascorbyl palmitate as representative VCDs. Ascorbyl phosphate and ascorbyl palmitate are VCDs with different substituted positions. Both of them increase Ru(bpy)(3)(2+) ECL, indicating that other VCDs may also enhance Ru(bpy)(3)(2+) ECL signal. The calibration plot for ascorbyl phosphate is linear from 3×10(-6) to 1.0×10(-3) M with a detection limit of 1.4×10(-6) M at a signal-to-noise ratio of 3. The relative standard deviation is 3.6% for six replicate measurements of 0.01mM ascorbyl 2-phosphate solution. The proposed method is about one order of magnitude more sensitive than electrochemical and UV-vis methods for the determination of ascorbyl phosphate, and is used successfully for the determination of ascorbyl phosphate in whitening and moisturising body wash.

Abstract
Tripropylamine (TPA) has different oxidation efficiency at double stranded (ds)-and single stranded (ss)-DNA-modified electrodes. Using this property, a simple but sensitive biosensor using TPA oxidation to probe the intramolecular displacement was constructed with the analysis of lysozyme as model for the first time. After the complementary ss-DNA strand of anti-lysozyme aptamer was immobilized onto gold electrode via gold-thiol bond, the incubation with the aptamer resulted in the formation of ds-DNA. Lysozyme (in 10 μL sample) binding with aptamer displaced the complementary strand because of the high affinity of lysozyme and its aptamer, corresponding to the dissociation of the ds-DNA. The modified electrode was swept in 20mM TPA solution from 0.2 to 0.95 V. The difference in oxidation current was used to quantify the content of lysozyme with a linear range from 1.0 pM to 1.1 nM. That means 10 amol or 6.0 × 10(6) lysozyme molecules can be detected. Because the signal is produced from the preconcentrated TPA at the electrode surface, the high sensitivity is achieved over the single site labelling strategy. The proposed method is simple, stable, specific, and time-saving while the complicated sample pre-treatment and the labelling to the DNA strand are avoided. The biosensor was validated by the analysis of the diluted egg white sample directly. The recovery and reproducibility were 93.3-100% and 1.4-4.2%, respectively.

Abstract
Electrochemiluminescence (ECL)-based biosensors are often used in the field of DNA- and protein-assay. Although ruthenium complex-based ECL is sensitive, its high exciting potential may lead to oxidation damage to biomolecules. For the first time, a non-damaging, low potential ECL aptasensor was constructed for bioassay with lysozyme as a model. After a single-stranded anti-lysozyme aptamer was attached to a gold electrode, a double stranded (ds)-DNA formed with its complementary strand. Ru(phen)(3)(2+), as an ECL probe, was intercalated into the ds-DNA. The hybridization of lysozyme with its aptamer led to the dissociation of ds-DNA because of the high stability of the aptamer-lysozyme and therefore the Ru(phen)(3)(2+) intercalated into ds-DNA was released. A low potential ECL was observed at the ds-DNA-modified electrode because ds-DNA was able to preconcentrate tripropylamine (TPA) and acted as the acceptor of the protons released from protonated TPAH(+). While the DNA sequence (anti-lysozyme aptamer) was used as the special recognition element for lysozyme, the formed ds-DNA also provided a micro-environment for low potential ECL. The low potential ECL aptasensor achieved the determination of lysozyme with a detection limit of 0.45 pM. The day-to-day precision (RSDs, n = 5) for the determination of lysozyme was lower than 5%, showing the reliability of the aptasensor. The regeneration of the aptasensor confirmed that the low potential for ECL could decrease oxidation damage to biomolecules. Further, the proposed method was successfully used to analyze diluted egg white sample directly. The protocol exhibited a promising platform for sensitive bioassay and could be further applied for the development of other low potential ECL sensing systems.

Abstract
Herein, for the first time, the electrochemiluminescent sensor based on Ru(bpy)32+-modified electrode using dopamine as an adhesive was successfully developed. After halloysite nanotube slurry was cast on a glassy carbon electrode and dried, an alkaline dopamine solution was added on the electrode surface. Initially, polydopamine belts with dimensions of tens to hundreds of nanometers formed via oxidization of the dopamine by ambient oxygen. As the incubation time increased, the nanobelts became broader and then united with each other to form a polydopamine film. The halloysite nanotubes were embedded within the polydopamine film. The above electrode was soaked in Ru(bpy)32+ aqueous solution to adsorb Ru(bpy)32+ into the active sites of the halloysite nanotubes via cation-exchange procedure. Through this simple procedure, a Ru(bpy)32+-modified electrode was obtained using only 6.25 µg Ru(bpy)32+, 15.0 µg dopamine, and 9.0 µg halloysite nanotubes. The electrochemistry and electrochemiluminescence (ECL) of the modified electrode was investigated using tripropylamine (TPA) and nitrilotriacetic acid (NTA) as co-reactants. The different ECL behaviors of the modified electrode using NTA and TPA as well as the contact angle measurements reflected the hydrophilic character of the electrode. The results indicate that halloysite nanotubes have a high loading capacity for Ru(bpy)32+ and that dopamine is suitable for the preparation of modified electrodes.
