Abstract:
A method for capturing an analyte, comprising the sequential steps of:contacting the analyte with a biosensor surface, the surface having a ligand bound thereto, so as to form an an analyte:surface-bound ligand interaction pair; detecting the binding of the analyte to the surface-bound ligand; eluting the analyte from the surface-bound ligand by contacting the biosensor surface with a first liquid that dissociates the analyte from the surface-bound ligand to generate a free analyte within the fist liquid; capturing the free analyte with a particulate solid capturing material within the first liquid, to thereby generate a first liquid containing captured analyte; removing the particulate solid capturing material, having the captured analyte associated therewith, to a location remote from the biosensor surface and consolidating the particulate solid capturing material, having the captured analyte associated therewith, at said location; and freeing the analyte from the particulate solid capturing material.
