Measurement of electrostatic potentials above oriented single photosynthetic reaction centers
Article Abstract:
It has been possible to make direct measurements of photovoltages produced by a single photosystem I (PS I). This research used the technique of Kelvin force probe microscopy in the heterostructure made up of PS I, 2-mercaptoethanol and atomically flat gold.

Molecular photovoltaics and surface potentials at the air-water interface
Article Abstract:
The quantitative light-induced electrostatic measurements of photosystem I (PSI) reaction centers using atomic force microscope (AFM) and the scanning surface-potential microscope (SSPM) is reported. The results indicate that the surface dipole forces and orientation of water molecules causes a net interfacial orientation of PSI molecules and light-induced surface potential that is related to the PSI concentration and photoactivity.

Imaging nanometer metallocatalysts formed by photosynthetic deposition of water-soluble transition-metal compounds
Article Abstract:
A method of imaging nanometer metallocatalysts formed by photosynthetic precipitation of the water-soluble transition-metal compounds [PtCl(sub 6)](super 2-) and [RuCl(sub 6)](super 2-) is reported. The use of this method can potentially create nanometer-sized Pt and/or bimetallic catalysts on biomembranes and molecules at pH 7 and room temperature with preservation of the biological function of the molecules.
