Abstract

The present invention relates to a biosensor to which an electroresponsive polymer layer is attached, and more specifically to a biosensor which comprises an electroresponsive polymer layer attached to the surface of a bioreceptor, and electrodes connected to the electroresponsive polymer layer, and which allows reversible deformation of the electroresponsive polymer layer when an electrical stimulus is supplied to an electrode, and can thereby analyse the concentration of an analyte when the surface of the bioreceptor is exposed to the analyte. When used as an implantable biosensor, the biosensor of the present invention is advantageous in that the time period for which and the frequency with which the bioreceptor is exposed to the analyte can be adjusted, and thus the lifespan of the biosensor is considerably extended.
