Sensitive Magnetic Catch Assay By Building a Strong Binding Couple

摘要

The invention relates to a sensor device for detecting a target in a sample suspected of comprising the target, which device is suitable for use in an assay such as a sandwich assay. The invention further relates to a method for detecting a target in a sample. The device comprises a sensor surface, which is functionalised with one moiety of a strong binding couple, which moiety preferably shows little or no cross reactivity with the target molecule.
