| 摘要 |
An object of the present invention is to provide a biosensor comprising a hydrogel capable of immobilizing a physiologically active substance thereon, which can be produced conveniently by use of a safe material, and a method for producing the same. The present invention provides a method for producing a biosensor, which comprises bringing a polymer containing an activated carboxyl group into contact with a substrate surface coated with an organic layer having an amino group to thereby bind the polymer to the organic layer. In another embodiment, the polymer is hydrophilic, e.g. dextran, and is applied to the surface as a thin film. |
