ELECTROCHEMICAL ASSAY

摘要

An electrochemical assay uses paramagnetic particles (10) including a coating of electroactive material (12) in order to detect or measure an analyte (30) of interest. The analyte is brought within the vicinity of an electrode (42) along with the coated paramagnetic particles (10). Application of a potential converts the electroactive coating (12) on the paramagnetic particles (10) into ions that can be measured using for example anodic stripping voltammetry. The level of ions corresponds to the amount of analyte (30) of interest in the sample.
