Abstract: A process for reacting a target molecule with at least two different enzymes involving the steps of: (a) providing at least one target molecule; (b) providing at least one reaction zone; (c) providing at least two different enzymes, present in the reaction zone, wherein at least one of the enzymes is immobilized therein; (d) introducing the target molecule into the reaction zone; and (e) reacting the target molecule, with the enzymes, in the reaction zone.

Abstract: Biomolecules such as enzymes can be immobilized on a surface by a process which comprises the steps of: (1) fixing a compound having a functional group selected from the group consisting of a carboxyl group, an amino group, a hydroxy group, a thio group and a combination thereof to a surface by plasmachemical modification of the surface to form a fixed surface; (2) binding a biomolecule to the fixed surface by reaction of the biomolecule with one or more of the functional groups.
