S-layer

S-layers in general

Molecular nanotechnology, especially nanobiotechnology starts to use and modify functionalize surfaces. Especially the immobilization of self-assembling biomolecules draws an increasing attention. The advantages of using immobilized enzymes in well-defined positions on nano-structured surfaces may even be greater. Self-assembly is an organization of molecules into defined structures, lowering the free energy of the system. Interaction between the molecules is non-covalent (e.g. hydrophobic-hydrophobic, van der Waals forces, molecular stacking) ([http://onlinelibrary.wiley.com/doi/10.1002/smll.200700200/abstract Schäffer et al., 2007])
