Abstract
This review focuses on recent developments in immunochemical methods for detection of mycotoxins, with a particular emphasis on simultaneous multiple analyte determination. This includes high-throughput instrumental analysis for the laboratory environment (microtitre plate enzyme-linked immunoabsorbant assay (ELISA), different kinds of immunosensors, fluorescence polarization immunoassay, and capillary electrophoretic immunoassay), as well as rapid visual tests for on-site testing (lateral-flow, dipstick, flow-through and column tests). For each type of immunoassay, perspectives for multiple analyte application are discussed and examples cited.

Abstract
Small molecule detection poses special problems during analysis whether hormones in a clinical setting or pesticides from environmental monitoring. Traditional analysis involves procedures like high-pressure liquid chromatography, gas chromatography, or mass spectrometry, or a combination of the three. Microarray procedures have recently evolved into a technique capable of replacing many of these assays, utilizing the strong and specific binding of a binder (e.g., an antibody) to a given target, even in a quantitative manner. A higher sensitivity can be obtained using microarrays were shown, even without the concentration of the sample beforehand. The sensitivity is high enough for monitoring most clinically relevant markers current regulatory pesticide levels. The microarray technique has additionally parallelism in sample analysis. The same sample can be analyzed for many targets at the same time, and under the same conditions. In the present protocol pesticide detection by microarray analysis is presented.

Abstract
A novel flow-through immunosensing system for performing a multianalyte chemiluminescent determination in a single run was designed. A new analytical strategy of substrate zone-resolved technique was proposed. Using carcinoma antigen 125 (CA 125) and carcinoembryonic antigen (CEA) as model analytes, the capture antibodies for CA 125 and CEA were immobilized on an UltraBind aldehyde-activated membrane to act as an immunoreactor, to which the mixture of CA 125, CEA, and their corresponding tracers, horseradish peroxidase (HRP)-labeled anti-CA 125 and alkaline phosphatase (ALP)-labeled anti-CEA, was introduced for on-line incubation. The substrates for HRP and ALP were then delivered into the detection cell sequentially to perform substrate zone-resolved immunoassay by a sandwich format. Under optimal conditions, CA 125 and CEA could be assayed in the ranges of 5.0-100 units/mL and 1.0-120 ng/mL, respectively. The whole assay process including incubation, wash, detection, and regeneration could be completed in 35 min. The serum samples from the clinic were assayed with the proposed method, and the results were in acceptable agreement with the reference values. This method and the strategy of substrate zone-resolved technique could be further developed for high-throughput multianalyte immunoassay.

Abstract
A direct competitive chemiluminescent immunosensor system that exploits the competition between chloramphenicol (CAP) as an analyte and CAP-horseradish peroxidase conjugate as a tracer for binding to an anti-CAP antibody on a solid support was devised by installing a flow-through cell which was connected to an injector and a peristaltic pump inside a dark box, followed by positioning a photomultiplier tube as light detector in front of it. The anti-CAP antibody was immobilized onto positively charged Biodyne B membrane pieces by a dipping procedure. The operating conditions for the immunosensor were selected with respect to substrate composition (0.25, 13.3 and 0.66 mM for luminol, H2O2 and p-iodophenol, respectively), injection volume of the substrate solution (200 microL) and the concentrations of antibody for immobilization (0.10 mg mL(-1)) and tracer (0.030 mg mL(-1)). At these conditions, sensor response according to analyte concentration was well fitted to a linear equation when plotted in semi-logarithmic scale, with the limit of detection for CAP of 10(-8) M. By using the immunosensor, CAP measurement in the model samples prepared from five food materials was conducted.

Abstract
In this paper a continuous-flow chemiluminescence (CL) system with artificial neural network calibration is proposed for simultaneous determination of rifampicin and isoniazid. This method is based on the different kinetic spectra of the analytes in their CL reaction with alkaline N-bromosuccinimide as oxidant. The CL intensity was measured and recorded every second from 1 to 300 s. The data obtained were processed chemometrically by use of an artificial neural network. The experimental calibration set was 20 sample solutions. The relative standard errors of prediction for both analytes were approximately 5%. The proposed method was successfully applied to the simultaneous determination of rifampicin and isoniazid in a combined pharmaceutical formulation.

Abstract
To replace a pesticide immunoassay based on microtiter plates, we have developed a quantitative, competitive microarray immunoassay, which permits rapid and highly sensitive quantification of the dichlobenil degradation product 2,6-dichlorobenzamide (BAM), and the prominently used herbicide atrazine. The pesticide analysis is based on the competitive binding of fluorescence conjugated monoclonal antibodies (mAb) to their respective analytes. Lowest detection limits were calculated to 1 ng/l (5 pM) for BAM and 3 ng/l (10 pM) for atrazine. Corresponding IC(50) values were, 10 ng/l (50 pM) for BAM and 34 ng/l (160 pM) for atrazine, respectively. In comparison to the existing microtiter plate immunoassay, the microarray was found to be up to 20-fold more sensitive. Compared to the gas chromatography with mass spectroscopy (GCMS) analysis performed on more than 1000-fold concentrated samples, the microarray-based immunoassay was even 10-fold more sensitive using non-concentrated samples. Measuring both analytes simultaneously did not affect assay sensitivity compared to single analyte quantification. Besides a gain in sensitivity and the possibility of multiplex quantification, assay times and assay complexity were reduced drastically with the microarray platform compared to the microtiter plate immunoassay and GCMS, suggesting that the microarray based immunoassay is a viable method for measuring picomolar amounts of analytes, e.g. clinically relevant analytes.

Abstract
A biosensor system based on total internal reflectance fluorescence (TIRF) was used to discriminate a mixture of the triazines atrazine and simazine. Only cross-reactive antibodies were available for these two analytes. The biosensor is fully automated and can be regenerated allowing several hundreds of measurements without any user input. Even a remote control for online monitoring in the field is possible. The multivariate calibration of the sensor signal was performed using artificial neural networks, as the relationship between the sensor signals and the concentration of the analytes is highly non-linear. For the development of a multi-analyte immunoassay consisting of two polyclonal antibodies with cross-reactivity to atrazine and simazine and different derivatives immobilised on the transducer surface, the binding characteristics between these substances like binding capacity and cross-reactivity were characterised. The examination of three different measurement procedures showed that a two-step measurement using only one antibody per step allows a quantification of both analytes in a mixture with limits of detection of 0.2 microg/l for atrazine and 0.3 microg/l for simazine. The biosensor is suitable for online monitoring in the field and remote control is possible.

Abstract
An imaging assay analogous to competitive enzyme immunoassays has been developed using a molecularly imprinted polymer instead of an antibody. The antigen 2,4-dichlorophenoxyacetic acid (2,4-D) was labeled with tobacco peroxidase, and the chemiluminescence reaction of luminol was used for detection. Microtiter plates (96 or 384 wells) were coated with polymer microspheres imprinted with 2,4-D, which were fixed in place by using poly(vinyl alcohol) as glue. In a competitive mode, the analyte-peroxidase conjugate was incubated with the free analyte in the microtiter plate, after which the bound fraction of the conjugate was quantified. After addition of the chemiluminescent substrates, light emission was measured in a high-throughput imaging format with a CCD camera. Calibration curves corresponding to analyte concentrations ranging from 0.01 to 100 microg/mL were obtained.
