A regenerable immunochip for the rapid determination of 13 different antibiotics in raw milk.

Access to high-quality and safe food is a basic need in our community and, consequently, the European Union has defined maximum residue levels (MRLs) for a number of antibacterial compounds. However, despite the obvious demand for quantitative multi-residue detection methods that can be carried out on a routine basis, there is currently a lack in the development of such systems. In particular, an automated multianalyte detection instrument is needed that is capable of quantifying several antibiotics simultaneously within minutes.

Development of an open stand-alone platform for regenerable automated microarrays.

A novel automated chemiluminescence (CL) read-out system for analytical flow-through microarrays based on multiplexed immunoassays has been developed. The microarray chip reader (MCR 3) is designed as a stand-alone platform, with the goal to quantify multiple analytes in complex matrices of food and liquid samples for field analysis or for routine analytical laboratories. The CL microarray platform is a self-contained system for the fully automated multiplexed immunoanalysis: the microarray chip, the fluidic system and the software module enable automated calibration and determination of analyte concentrations during a whole working day.
