    摘要: Disclosed are immunoassay displacement methods for detecting (preferably identifying) the presence or amount of a target analyte (e.g. drug) in a sample comprising the steps of: (a) exposing the sample to a complex comprising an immobilised antibody capable of specifically binding the analyte, said antibody being specifically bound to a displacement agent, wherein said agent comprises: (i) an analyte analog capable of specifically binding the antibody, (ii) a SE(R)RS active label, (iii) a SE(R)RS surface-seeking group (e.g. benztriazole), whereby any analyte present in the sample causes the displacement of agent from the antibody; (b) exposing any displaced agent to a SE(R)RS surface; and, (c) detecting any displaced agent associated with said surface using SE(R)RS. In preferred forms of the invention several target analytes are detected from a single source or sample simultaneously. Also provided are agents per se e.g. for use in drug or explosive detection. These may include chromophores and linking groups.

    摘要: A method, composition, device, apparatus, and kit for the determination of the presence or amount of an analyte by monitoring an analyte-mediated ligand binding event in a test mixture which contains the analyte to be assayed, a specific binding member, a Raman-active label, and a particulate having a surface capable of inducing a surface-enhanced Raman light scattering. The test mixture is illuminated with a radiation sufficient to cause the Raman-active label in the test mixture to emit a detectable Raman spectrum. The differences in the detected surface-enhanced Raman scattering spectra are dependent upon the amount of the analyte present in the test mixture. Thus, by monitoring these differences, the presence or amount of the analyte are determined.
