Biosensor for detection of microorganisms, polynucleotide sequences, peptides, polypeptides, metal ions or organic molecules using auxiliary electrode, reference electrode and at least one working electrode

摘要

The biosensor (100) has an auxiliary electrode (106), a reference electrode (104) and at least one working electrode (105), positioned in a symmetrical arrangement on a chemically-inert carrier (101), e.g. a printed circuit board. Independent claims are also included for: (1) a device incorporating a biosensor; (2) a system for detection of target biomolecules in a sample; and (3) a kit containing a biosensor, a device incorporating a biosensor, or a system for detection of target biomolecules.
