Recent Advances in Electrochemiluminescence Analysis

“…87 Besides, the biological toxicity and volatile nature of those coreactants may sophisticate the operation and increase the measurement error. 87,88 Recently the self-enhanced ECL luminophore is proposed by covalently linking the ECLactive luminophore and coreactant into one molecule, which can generate enhanced ECL signal through intramolecular interaction. 89−91 The intramolecular interactions between luminophore groups and coreactant groups can shorten the electronic transmission distance and improve the luminous stability, thus enhancing the luminous efficiency.…”

“…The multiantibody amplification strategy that uses H-rGO-AuNRs as a nanocarrier possesses excellent performance for CEA detection with a detection limit of 0.01 pg mL –1 . Yuan’s group synthesized a series of materials that included palladium nanowires, manganese ion doped zinc oxide nanorods, PdCu nanocubes that supported carbon nanohorns, and core–shell Pd–Au hexoctahedrons, which served as nanocarriers for loading antibodies.…”

Target-catalyzed hairpin assembly and intramolecular/intermolecular co-reaction for signal amplified electrochemiluminescent detection of microRNA

“…Based on the consideration, the self-enhanced luminophore is proposed to obtain a highly luminous efficiency, which is commonly synthesized by covalently linking the ECL-active luminophore and coreactant into one molecule for shortening the electronic transmission distance, improving the luminous stability and enhancing the luminous efficiency (Swanick et al, 2012). Recently, we have developed highly sensitive ECL biosensors based on the novel self-enhanced ECL luminophore, which exhibited satisfactory performances with wider linear range and good stability Wang et al, 2015). However, when another coreactant was introduced in the self-enhanced ECL system, how the ECL emissions would be influenced?…”
