Multi-walled carbon nanotubes (MWCNTs) were decorated with cobalt nanoparticles (CoNPs) by a simple thermal decomposition method. The prepared nanohybrid material (nanoCoMWCNTs) was then cast on the surface of a glassy carbon electrode (GCE) as a novel electrocatalyst for the construction of a sensitive electrochemiluminescence (ECL) sensor. The fabricated sensor (GCE/nanoCo-MWCNTs/Nafion) showed excellent electrocatalytic activity toward luminol and H 2 O 2 oxidation reactions at neutral media. Under optimal experimental conditions, the ECL signal intensity of the sensor was linear with the concentration of luminol in the range between 80 nM and 140 µM (r = 0.9963) and also with the concentration of H 2 O 2 in the range between 1 nM and 240 µM (r = 0.9980). Detection limits (S/N = 3) for luminol and H 2 O 2 were 8.7 and 0.2 nM, respectively. The relative standard deviations (RSD) for repetitive  ACCEPTED MANUSCRIPT 2 measurements of 100 µM luminol (n =10) and 10 µM H 2 O 2 (n=11) were 1.6% and 2.0%, respectively. Also, the prepared sensor was further modified with glucose oxidase (GOx) to fabricate a glucose ECL based biosensor (GCE/nanoCo-MWCNTs/GOx/Nafion). The fabricated ECL biosensor exhibited excellent performance toward glucose detection in the concentration range between 0.5 and 600 µM with a satisfactory detection limit (50 nM) and reproducibility (2.3%).Electrogenerated chemiluminescence or electrochemiluminescence (ECL) is an attractive analytical tool with broad applications in different research areas. ECL is a hybrid technique which provides electrochemical and spectral information, simultaneously [1]. Simple and lowcost instrumental set up, excellent sensitivity and low background signal are the most important features of ECL [2,3]. A increased interest is observed for ECL investigations and this fact has been reflected in the number of reviews [4][5][6][7][8][9] which report the effectiveness of ECL detection method and its wide analytical applications.Luminol (2, 3-aminophthalhydrazide) is the most popular organic luminescent species which can be oxidized at the electrode surface. The subsequent chemical reaction between the oxidized luminol and H 2 O 2 (or O 2 ) produces ECL signal. Since the first report on the observation of ECL response for luminol at the electrode surface in alkaline solution [10], numerous attempts have been done to find effective approaches for the enhancement of ECL signal intensity of luminol in neutral medium [11][12][13][14]. It has been shown that the ECL reaction of luminol with oxygen or hydrogen peroxide is more efficient in alkaline medium through modification of the electrode surface with nano-materials [12,15].With the development of nanotechnology, various types of nano-structured materials with outstanding properties are being synthesized and applied for the construction of novel sensors and biosensors. Nano-structured materials provide higher effective surface area and higher catalytic activity in comparison with their respective bulk materials. The catalyti...

“…Composite particles of Fe 3 O 4 /GOD were adhered by Qiang and his group onto solid paraffin carbon paste electrode surface by magnetic force to act as a working electrode. H 2 O 2 was produced by enzymatic reaction of GOD, and ECL could be obtained by the reaction between luminol and H 2 O 2 for sensing glucose [69]. A FI optical fiber glucose and lactate biosensor [70][71][72] and a thin-film glucose ECL biosensor were also developed based on alcohol-free mesoporous molecular sieve silica modified electrode [73] and immobilization of GOD with MWNT/ Nafion film [74][75][76].…”

The development of electrochemiluminescence (ECL) applications is a growing field, having the potential advantages of ECL over conventional chemiluminescence. ECL has found various applications in immunoassays, DNA probe assays, and aptasensors by employing ECL-active species as labels on biological molecules. The recent use of ECL to detect many chemically, biochemically, clinically, and environmentally important analytes is reviewed.
