A planar array immunosensor, equipped with a charge-coupled device (CCD) as a detector, was used to simultaneously detect 3 toxic analytes. Wells approximately 2 mm in diameter were formed on glass slides using a photoactivated optical adhesive. Antibodies against staphylococcal enterotoxin B (SEB), ricin, and Yersinia pestis were covalently attached to the bottoms of the circular wells to form the sensing surface. Rectangular wells containing chicken immunoglobulin were used as alignment markers and to generate control signals. After removing the optical adhesive, the slides were mounted over a scientific grade CCD operating at ambient temperature in inverted (multipin phasing) mode. A two-dimensional graded index of refraction lens array was used to focus the sensing surface onto the CCD. Solutions of toxins were then placed on the slide. After rinsing, Cy5-labeled antibodies were introduced. The identity and amount of toxin bound at each location on the slide were determined by quantitative image analysis. Concentrations as low as 25 ng/mL of ricin, 15 ng/mL of pestis F1 antigen, and 5 ng/mL of SEB could be routinely measured.
