Sensor Microtiter Plates for Bioanalysis
We develop microtiter plates with integrated sensor membranes for analyte enrichment and optical sensing. This merges the inherent advantages of microplates (high sample throughput, saving of sample and reagent volume, statistically validated readout) with those of optical sensors (continuous readout over hours, use of all optical detection methods).
Over the past years, microplates for ion analysis (e.g. Cu(II), phosphate, citrate), pH measurement and quantitation of biogenic amines, DNA, pesticides and for the screening for antibiotics were developed.
