Abstract: The present invention relates to an adhesive material being composed and/or consisting of at least one protein obtained or obtainable from flagella from archaea. Furthermore, the present invention relates to the use of at least one protein obtained from flagella from archaea for the method for the preparation of an adhesive material comprising the step of isolating and/or purifying at least one protein obtained from flagella from archaea.

Abstract: Biochemical substances, such as enzymes, are immobilized using an olefinic-unsaturated, epoxyfunctional polysiloxane. The polysiloxane is applied to a carrier material. The polysiloxane on the carrier is cross-linked by using high-energy radiation or a peroxide to form a polymer matrix. The polymer matrix is treated with an aqueous solution of a biochemical substance that reacts with epoxy groups and becomes immobilized. The polymer matrix is stabilized by the reaction of non-reacted epoxy groups with a compound containing an amino group, a carboxyl group or an amino group and a carboxyl group. The crosslinked polysiloxane can be hydrophilized after cross-linking and prior to immobilization of the biochemical substance by the reaction of a portion of the epoxy groups with a hydrophilic compound.

Abstract: A biosensor is prepared having a selective detection system containing a biochemical substance such as an enzyme immobilized on an olefinic-unsaturated, epoxyfunctional polysiloxane. Prior to immobilization of the biochemical substance, the polysiloxane is applied as a layer to a carrier and cross-linked by treatment with high-energy radiation. A biochemical substance is reacted with epoxy groups of the cross-linked polysiloxane. Any non-reacted epoxy groups are reacted with a compound containing an amino group, a carboxyl group or an amino group and a carboxyl group to stabilize. After cross-linking and before reacting of the biochemical substance, the cross-linked polysiloxane can be hydrophilized by reacting some of the epoxy groups with a hydrophilic compound containing a reactive group.
