Pastes made of carbonaceous materials with ionic liquids acted also as heated electrochemiluminescence sensors. A mixture of multi-wall carbon nanotubes with an ionic liquid was used in connection with lucigenine to detect ascorbic acid which influences the luminescence of the latter [68]. Another example was a carbon/ionic liquid paste electrode where Ne-isopentenyl-adenine was detected using its enhancement action on the electrochemiluminescence of ruthenium bipyridyl [69]. [Pg.113]

In a series of papers, heated indium tin oxide (ITO) electrodes were proposed as carriers for electrochemiluminescent sensors of diverse analytes [70-74]. The system couples the advantages of a heated electrode with the optical transparency property of ITO glass. In [70], H2O2/MCLA and TPrA/Ru(bpy)3 have been used to test the arrangement which was constructed very similar to the scheme given in Fig. 6.15. In [71], TPrA and colchicine were detected in human serum by means of the ruthenium bipyridyle ECL system. Immobilised xanthine oxidase as a sensor system for hypoxanthine has been mentioned already. It has been used also with a heated ITO electrode [72]. Further examples for electrochemiluminescence detection with heated ITO electrodes were the analysis of Ns-methyladenosine in urine...

A new cholesterol flow injection analysis biosensor has also been described as an application of the H2O2 ECL sensor56. In that work, the luminol electrochemiluminescence, previously studied in aqueous media, was implemented in Veronal buffer added of 0.3% triton X-100 (v/v), 0.3% PEG and 0.4% cholate to enable the solubilisation of the cholesterol and then its efficient oxidation catalyzed by the immobilized cholesterol oxidase. The ECL reaction occurred thus in a micellar medium and the performances of the H2O2 ECL sensor were investigated. [Pg.171]

The model immunoassay is the enzyme-linked immunosorbent assay (ELISA) in which a non-specific capture antibody is bound to a surface, such as a multi-well plate or small tube [13]. In the basic form of ELISA, a second antibody tagged with an enzyme interacts specifically with the analyte. The enzyme assay produces a colored product that is read with a spectrophotometer. There are many variations on the basic immunoassay format that serve to increase sensitivity, specificity, linear range, and speed. Many commercial instruments have been developed to take advantage of various technologies for reporter molecules. The immunoassay may be coupled to an electronic sensor and transducer, such as a surface acoustical wave (SAW) sensor. Electrochemiluminescence (ECL) is a method in which the detector antibody is tagged with a ruthenium-containing chelate [13-15]. When the tag is... [Pg.777]

There is increasing interest in the use of specific sensor or biosensor detection systems with the FIA technique (Galensa, 1998). Tsafack et al. (2000) described an electrochemiluminescence-based fibre optic biosensor for choline with flow-injection analysis and Su et al. (1998) reported a flow-injection determination of sulphite in wines and fruit juices using a bulk acoustic wave impedance sensor coupled to a membrane separation technique. Prodromidis et al. (1997) also coupled a biosensor with an FIA system for analysis of citric acid in juices, fruits and sports beverages and Okawa et al. (1998) reported a procedure for the simultaneous determination of ascorbic acid and glucose in soft drinks with an electrochemical filter/biosensor FIA system. [Pg.126]

CNTs also have promising applications in the immunosensing field and many examples of such sensor devices can be found in the literature. For example, immunosensors with an electrochemiluminescence readout signal have been designed using CNTs as support of the immunorecognition systems [167]. [Pg.156]
