Multi-analyte interrogation using the fiber optic biosensor

The capabilities of the portable, automated fiber optic biosensor, RAPTOR, have recently been evaluated. Developed to perform rapid fluoroimmunoassays in the field, the RAPTOR was designed to test samples for up to four diffe rent target analytes simultaneously. Assay time could be varied from a 3-mi n rapid screen to a standard 10-min test. A trial of 203 blind samples test ed for Staphylococcal enterotoxin B, ricin, Francisella tularensis, and Bac illus globigii has been conducted. Sensitivities obtained were 10, 50 ng/ml , 5 x 10(5), and 5 x 10(4) cfu/ml, respectively. (C) 2000 Elsevier Science S.A. All rights reserved.
