description

Abstract We describe here the development of a new, non-isotopic immunological assay termed CMIA (carbonyl metallo immunoassay) that uses metal carbonyl complexes as tracers and Fourier transform infrared spectroscopy (FT-IR) as the detection method. This assay is based on the particular spectral features of these complexes, which show very strong absorption bands in the 1800–2200 cm −1 spectral range where proteins and organic molecules do not absorb. In Section 1 , the optimisation of the quantitative detection of these tracers is detailed. In Section 2 , the implementation of mono-CMIA is described, including the CMIA assays of three antiepileptic drugs (carbamazepine, phenobarbital, phenytoin). Finally, extension to the simultaneous double- and triple-CMIA of these drugs is reported.
