Publication number: 20140251832Abstract: 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 of interest in the sample.Type: ApplicationFiled: October 22, 2012Publication date: September 11, 2014Inventor: Robert Andrew Porter

Patent number: 8617907Abstract: A method for determining the presence or amount of a metal-labelled species in a sample may include causing the metal of the metal-labelled species in the sample to form a soluble electrochemically-active complex which is stable relative to moieties present or potentially present in the sample which will form an insoluble and/or electrochemically-inactive complex with the metal, and electrochemically measuring the formed complex to provide an indication of the presence or amount of the metal-labelled species.Type: GrantFiled: June 7, 2005Date of Patent: December 31, 2013Assignee: Alere Switzerland GmbHInventors: Brian Jeffrey Birch, Camilla Sofia Forssten, Alena Kabil, Robert Andrew Porter

Patent number: 8337692Abstract: A method for determining the presence or amount of a metal-labelled analyte (12) in a sample is described. The method comprises the steps of adding a release agent (20) to the metal labelled analyte (12) to release the metal label (18) from the analyte (12), the release agent (20) forming a charged stable species (22) with the metal label (18), applying a potential to bring the charged stable species (22) to an electrode (22), dissolving the charged stable species (22) under a positive potential to form metal ions (26), and carrying out a quantitative determination procedure such as anodic stripping voltammetry to determine the presence or amount of the metal-labelled analyte (12).Type: GrantFiled: November 25, 2008Date of Patent: December 25, 2012Assignee: The Secretary of State for Innovation, Universities and Skills of Her Majesty's Britannic GovernmentInventors: Robert Andrew Porter, Mateusz Szymanski
