Abstract
A biosensor according to an embodiment of the present invention includes a substrate, a working electrode disposed on the substrate, and a reference electrode disposed on the substrate to be spaced apart from the working electrode. The working electrode includes a sensing electrode disposed on a top surface of the substrate, an enzyme reaction layer disposed on a top surface of the sensing electrode, and a permeation control layer disposed on a top surface of the enzyme reaction layer, and the permeation control layer includes a water-soluble polymer and a water-insoluble polymer. The permeation layer includes a mixture of the water-soluble polymer and the water-insoluble polymer to improve a sensing performance for a sensing target material.
