The unit addresses biotechnological questions involving the interface between biological structures and technical systems. Special focus is aimed at gaining as much analytical information as possible from very small quantities of material. The solution lies in the modification of the respective surfaces.
Surfaces with new characteristics or a so-called intelligent surface can be produced by using defined (bio)chemical functionalization (branched linkers) or by applying thin films (biopolymer-based membranes or switchable hydrogel layers). The technology is implemented both on geometric materials such as fibers as well as on planar media such as plates or chips. The surfaces themselves vary from glass and wafer materials to plastics.
The products developed by the unit are independent sensor elements (test strip based PoNd) or analyses and database tools (cell and peptide chips) and can be employed in various applications in the areas of environmental analysis, food industry monitoring, herd management, process control or diagnostics.
