Coreactants of tris(2,2′-bipyridyl)ruthenium(II) Electrogenerated Chemiluminescence

Flexible shrink-induced high surface area electrodes for electrochemiluminescent sensing

Photolithographically defined metallic thin film on commodity shrink-wrap is leveraged to create robust electrodes. By thermally shrinking the film, electrodes are reduced by 20× in footprint for improved resolution and conductivity with >600% enhancements in electrochemically active surface area; as electrochemiluminescent sensors, they demonstrate improved limits of detection.

A sensitive method for the determination of levamisole in serum by electrochemiluminescence

A novel method was developed for the determination of levamisole by electrochemiluminescence. The method was based on electrochemiluminescence signal enhancement produced by Ru(bpy)(3)(2+), which reacted with the tertiary amine group of levamisole on a platinum electrode in 12 mmol/L borate buffer (pH 9). A linear relationship between the luminous intensity and concentration of levamisole in the range 0-1 × 10(-7) mol/L was obtained and the detection limit was 1.76 × 10(-11) mol/L. The method is sensitive, selective, simple and convenient. The method has been successfully applied to the analysis of levamisole in serum.
