A rapid immunoassay for sensitive detection of microcystin-LR using a portable chemiluminescence multichannel immunosensor (CL-MADAG) was developed. The sensor device is based on a capillary ELISA technique in combination with a miniaturized fluidics system and uses chemiluminescence as the detection principle. Minimum concentrations of at least 0.2 mu g L(-1) microcystin-LR could be unambiguously measured in a spiked buffer system as well as in spiked real water samples. A single sample analysis for detection of microcystin-LR could be accomplished in just 13 min on the CL-MADAG. Besides providing a highly reproducible, fast and easy to perform test format, one major advantage of the newly established capillary immunoassay is represented by the feasibility of an internal retrospective quality control mechanism. Finally, simultaneous CL-MADAG measurements employing our inhibition immunoassay and a sandwich ELISA could be successfully demonstrated. (C) 2009 Elsevier B.V. All rights reserved.
