Inside Front Cover: A Photosynthetic Reaction Center Covalently Bound to Carbon Nanotubes (Adv. Mater. 22/2007)



On p. 3901, Shachar Richter, Alexander Holleitner, and co-workers report on a novel hybrid system, fabricated by covalent binding of photosynthetic reaction center protein photosystem I (PS I) to carbon nanotubes (CNTs) by using carbodiimide chemistry. The versatile chemical modification schemes allow contacting of single PS I protein to two carbon nanotubes, the formation of CNT–PS I–CNT junctions, and electrical contact of carbon nanotubes to gold electrodes via covalent binding to the photosystem. Such nanostructures can pave the way for the construction of electronic circuits for nano-optoelectronic applications.
