Within the last decades, more and more industrial processes use enzymes as catalysts for the production of fine chemicals and drugs. However, the low stability of the enzyme under non-physiological conditions often hinders a broad application. The immobilization of enzymes on solid supports is one possibility to overcome this limitation and to increase the enzyme stability. Therefore, a current challenge is to design tailor-made support materials, which can be adapted for the immobilization of various enzymes and possess a high loading capacity.

A new type of material called „metal organic frameworks“ (MOF) consists of metal ions and organic linkers. MOFs form a micro porous crystalline 3D structure with a well-defined pore size and a high surface area. Recent publications show that enzymes embedded in the micropores of the MOF are protected against denaturation even in non-physiological conditions.

This thesis investigates the synthesis of MOFs and their application as support material for enzyme immobilization. The thesis includes:

  • Synthesis of MOFs with high enzyme loading
  • Activity tests to determine the enzyme activity after immobilization
  • Establishment of a new fabrication method for enzyme/MOF membranes
  • Characterization of the resulting enzyme/MOF membrane
