Bioinspired Materials for Nanotechnology

Raff, J.

Bacterial S-layers are highly ordered paracrystalline protein polymers on the surface of many bacteria. During a long evolutionary process of billions of years, S-layers have been optimized as simple system to form regular lattices with different functions by self-assembly. Solutions of S-layer proteins can be used for the simple coating of a broad spectrum of different materials e.g. glas, silicon and ceramics with a mono-molecular protein layer. The well defined arrangement of different functional groups effects the selective binding of several metals or can be used for the regular immobilization of bio-functional molecules. Furthermore S-layers or S-layer coatings can be used as template for the controlled formation and immobilization of nano-particles. S-layer proteins are therefore very prospective for different bio- and nanotechnological applications, like the selective removal of metals, the production of noble metal catalysts and photo-catalysts and the development of sensory layers.
