Nanometer arrays of functional light harvesting antenna complexes by nanoimprint lithography and host-guest interactions

J Am Chem Soc. 2008 Jul 16;130(28):8892-3. doi: 10.1021/ja802843m. Epub 2008 Jun 21.

Abstract

We show an approach based on a combination of site-directed mutagenesis, NIL and multivalent host-guest interactions for the realization of engineered ordered functional arrays of purified components of the photosynthetic system, the membrane-bound LH2 complex. In addition to micrometer-scale patterned structures, we demonstrated the use of nanometer-scale hard NIL stamps to generate functional protein arrays approaching molecular dimensions.
