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; a counter electrode; at least one working electrode terminal; at least one counter electrode terminal; at least one first reference terminal; and at least one second reference terminal; wherein: the working electrode is connected to the at least one working electrode terminal and to the at least one first reference terminal; the counter electrode is connected to the at least one counter electrode terminal and to the at least one second reference terminal; and the number of working electrode terminals is different than the number of counter electrode terminals.
