Protein Assemblies on Gold using Polyelectrolytes for the Construction of Analytical Signal Chains

In biological signal transfer redox proteins play a key role. Often in a biological system they are arranged in a productive orientation allowing charge transfer from one molecule to the other. The transfer reaction can occur via mediators or by a direct interaction of the partners. These natural systems can be considered as an example for the development of artificial, biomimetic systems. The construction of such protein assemblies on electrodes has a great potential for the development of sensors but also for the design of electrodes for bioenergetic application.
