Abstract
A biosensor comprising an enzyme immobilized membrane in intimate contact with the front end of an optical fiber is disclosed. The biosensor can be produced by coating and impregnating a dialysis membrane with an enzyme and a photocrosslinkable resin, and then crosslinking the photocrosslinkable resin to immobilize the enzyme in the dialysis membrane, thereby obtaining an enzyme immobilized membrane; and bringing the enzyme immobilized membrane into intimate contact with the front end of an optical fiber. Since the optical fiber and the enzyme (enzyme immobilized membrane) are used in combination, the biosensor is highly sensitive and selective and can serve as an excellent odor sensor.
