Enzymatic modification of surfaces
Poly(ethersulfone) [PES] is a very popular material for the construction of membranes because of its sturdiness and chemical inertness. It is also a hydrophobic material and therefore prone to fouling by biopolymers like proteins, polysaccharides and polyphenols. Modification to make PES antifouling is difficult because of its inertness. We have found a very mild method to covalently modify PES, thereby strongly reducing its tendency to attract biopolymers. Our method involves oxidation of phenolic acids to radicals by the fungal enzyme laccase; the radicals subsequently couple to the PES and form brushes or layers. See the scheme and figure below. Further details can be found in the references.

Enzymes for detection
We also use enzymes for detection purposes, e.g. of masked mycotoxins and lactate (see Figure below and Alonso et al., 2016).
