270057 SE Chemical sensors and selforganisation (2007S)

In chemical sensors selforganized layers are favourably applied to different types of transducers, e.g. mass-sensitive devices or optical measurement principles. The strategies can range from hydrogen bond formation to gold-thiol interactions forming selfassembled monolayers and to the generation of highly cross-linked polymers. In this way selective inclusion of analytes can be performed in the bulk for small molecules. Even large bioanalytes can be recognized by surface patterning processes.
