The article was titled 《Electrogenerated Chemiluminescence from a Phenyleneethynylene Derivative and its Ultrasensitive Immunosensing Application Using a Nanotubular Mesoporous Pt-Ag Alloy for Signal Amplification》. The information in the text is summarized as follows:

Electrogenerated chemiluminescence (ECL) of a novel phenyleneethynylene derivative [4,4′-(2,5-dimethoxy-1,4-phenylene)bis(ethyne-2,1-diyl) dibenzoic acid; P-acid] possessing carboxylic acid groups at the para positions in aqueous solutions and its first immunosensing application were studied. Nanotubular mesoporous Pt-Ag alloy nanoparticles are first used to fabricate the ECL immunosensor as a signal amplification carrier. Absorption, photoluminescence, cyclic voltammetry, SEM, TEM, and electrochem. impedance spectroscopy were used as powerful tools to characterize P-acid, Pt-Ag alloy nanoparticles, and the fabrication process of the immunosensor. P-acid exhibits two ECL peaks at -1.07 (ECL-1) and 0.64 (ECL-2) V in air-saturated pH 7.4, 0.1 M PBS containing 0.1 M KCl during the cyclic sweep between 1.51 and -2.67 V at 0.1 V s-1; the ECL mechanism of these two ECL peaks is demonstrated. The electron-transfer reaction between electrochem. oxidized P-acid and tri-n-propylamine (TPrA) radical cation is also demonstrated to produce high ECL emissions and used to develop an ultrasensitive ECL immunosensor. In addition, a Pt-Ag alloy nanoparticles amplification carrier for protein ECL anal. is applied for improvement of the detection sensitivity. Thus, this ECL immunosensor exhibits high sensitivity, good reproducibility, rapid response, and long-term stability. The results came from multiple reactions, including the reaction of 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Recommanded Product: 74029-40-6)
