Biosensor, biosensor chip and biosensor device

摘要

A biosensor includes a working electrode 101, a counter electrode 102 opposing the working electrode 101, a working electrode terminal 103 and a working electrode reference terminal 10 connected to the working electrode 101 by wires, and a counter electrode terminal 104 connected to the counter electrode 102 by a wire. By employing a structure with at least three electrodes, it is possible to assay a target substance without being influenced by the line resistance on the working electrode side.

主权项

1. A biosensor, comprising:
a working electrode disposed on a proximal end of the biosensor; a counter electrode disposed on the proximal end of the biosensor; a working electrode terminal on a distal end of the biosensor; a counter electrode terminal on the distal end of the biosensor; a first reference terminal on the distal end of the biosensor; a second reference terminal on the distal end of the biosensor; a first conductive line connecting the working electrode to the working electrode terminal; a second conductive line connecting the working electrode to the first reference terminal, at least a portion of the second conductive line disposed outside at least a portion of the first conductive line relative to a centerline that extends between the proximal end and the distal end of the biosensor; a third conductive line connecting the counter electrode to the counter electrode terminal; and a fourth conductive line connecting the counter electrode to the second reference terminal, at least a portion of the fourth conductive line disposed outside at least a portion of the third conductive line relative to the centerline.
