Surface Analysis

Everywhere that biological structures encounter technical systems, biotechnological »interface problems« arise, that involve obtaining as much (analytical) information as possible from very little material. The solution to this is the modification of the respective surfaces.

By using defined (bio)chemical functionalization (branched linkers) or by applying thin films (biopolymer-based membranes or switchable hydrogel coatings), surfaces with new properties or so-called intelligent surfaces can be produced. The technological implementation involves the use of both geometric materials, such as fibers, and planar substrates, such as plates or chips. The actual surfaces range from glass and wafer materials to plastics.

The products are self-contained sensor elements (test strip-based PoNd) or analysis and database tools (cell and peptide chips) and can be employed for a range of different areas of inquiry in the fields of environmental analysis, food monitoring, herd management, process assurance or diagnostics.
