Excitation Laser

Fiber-optic biosensor uses light transmittable tapered fiber to send excitation laser light and receive emitted fluorescent light. The fluorescent light excited by an evanescent wave generated by the laser is quantitatively related to biomolecules immobilized on the fiber surface [1]. An automated fiber-optic biosensor based detection method for Listeria monocytogenes was developed in this research. Detections of Listeria monocytogenes in hotdog sample were performed to evaluate the method. By using the detection method with automated fiber-optic biosensor, 5.4×107 cfu/ml of Listeria monocytogenes was able to detect.

SummaryWe describe a rapid and sensitive method for detection and quantification of D-dimer and other crosslinked fibrin degradation products (XL-FDPs), which are present in elevated concentrations in patients with sepsis and thrombotic disorders. The method utilizes a sandwich fluoroimmunoassay immobilized in the sensing region of an evanescent wave biosensor. Physiological concentrations of D-dimer and high molecular weight XL-FDP could be determined in buffer and plasma samples on calibrated fibers in 11 min. Samples from septic patients were assayed using ELISA and the fiber optic method; concentrations determined by fiber optic assay were strongly correlated with those determined by ELISA (r = 0.918); intra- and inter-assay errors were comparable to those from ELISAs. Given its accuracy and rapid response time, this fiber optic biosensor shows great potential for development as a diagnostic tool.
