Abstract:
Chemiluminescence sensors are important tools in analytical chemistry due to their high sensitivity selectivity. This review presents the instrumentation involved in their design, including light detection and flow injection analysis system used. Various applications for the analysis of inorganic and organic compounds from gaseous samples and solutions indicate that these sensors are used with good reproducibility and selectivity of the analytes at low concentration level.

Abstract:
A flow injection analysis (FIA) manifold (described) with an anti-theophylline derivatized planar waveguide optical sensor was developed. The planar waveguides were produced by immersing Corning 0211 cover slips into AgNO3 - NaNO3 (1:9) at 280°C for 15 min to 1 h, and monoclonal mouse anti-theophylline IgG was coupled to the waveguide surface. Samples of theophylline (50 µL) were injected into the FIA manifold, and the flow was stopped for 5 min to 1 h to allow equilibration of the sample to the sensor surface. After incubation, the flow cell was flushed, followed by detection of the specifically bound liposomes at 516 nm (excitation at 488 nm). Antibody activity was regenerated by adding 1-O-octyl β-D-glucopyranoside for 2 min, then rinsing for 20 min with phosphate-buffered saline solution (pH 7.4). Sensors capable of >15 sequential measurements demonstrated >10% precision.
