Applications of Nanomaterials in Electrogenerated Chemiluminescence Biosensors
Electrogenerated chemiluminescence (also called electrochemiluminescence and abbreviated ECL) involves the generation of species at electrode surfaces that then undergo electron-transfer reactions to form excited states that emit light. ECL biosensor, combining advantages offered by the selectivity of the biological recognition elements and the sensitivity of ECL technique, is a powerful device...
متن کاملDevelopments and Applications of Electrogenerated Chemiluminescence Sensors Based on Micro- and Nanomaterials
A variety of recent developments and applications of electrogenerated chemiluminescence (ECL) for sensors are described. While tris(2,2'-bipyridyl)-ruthenium(II) and luminol have dominated and continue to pervade the field of ECL-based sensors, recent work has focused on use of these lumophores with micro- and nanomaterials. It has also extended to inherently luminescent nanomaterials, such as ...
متن کاملElectrogenerated chemiluminescence. 58. Ligand-sensitized electrogenerated chemiluminescence in europium labels.
The electrochemistry and electrogenerated chemiluminescence (ECL) of a series of europium chelates, cryptates, and mixed-ligand chelate/cryptand complexes were studied. The complexes were of the following general forms: EuL(4)(-), where L = β-diketonate, a bis-chelating ligand (such as dibenzoylmethide), added as salts (A)EuL(4), where A = tetrabutylammonium ion or piperidinium ion (pipH(+)); ...
متن کاملApplications of Nanomaterials in Electrochemical Enzyme Biosensors
A biosensor is defined as a kind of analytical device incorporating a biological material, a biologically derived material or a biomimic intimately associated with or integrated within a physicochemical transducer or transducing microsystem. Electrochemical biosensors incorporating enzymes with nanomaterials, which combine the recognition and catalytic properties of enzymes with the electronic ...
متن کاملElectrogenerated chemiluminescence 73: acid–base properties, electrochemistry, and electrogenerated chemiluminescence of neutral red in acetonitrile
We characterized the acid–base properties, electrochemistry, and electrogenerated chemiluminescence (ECL) of neutral red in acetonitrile (MeCN). To determine the acid–base properties, the basic form (NR) of neutral red was prepared and titrated with anhydrous HClO4, yielding pKa = 6.5 in MeCN. NR showed three irreversible electrochemical oxidations and a one-electron reversible reduction. Howev...
