Abstract
This proposal is directed towards establishing the conditions for immobilising components of the purple bacterial photosynthetic unit upon unmodified and modified substrates to permit their examination by atomic force microscopy and single molecule spectroscopy. Single molecule spectroscopy in combination with simultaneous atomic force microscopy will be used to reveal the effect of light-harvesting complex geometry upon spectral properties both in regular arrays and in isolated complexes. Immobilisation of LH complexes upon ultra small spots and narrow strips of gold will be used to examine unique combinations of complexes in isolation and to test the possibility of constructing high efficiency nanoscale light guides.
