摘要：
The electron transfer coupling element between gold nanoclusters and the photosynthetic reaction center protein from the bacterium Rhodobacter sphaeroides was calculated using the shortest-path algorithm. Changing the size of the metal cluster alters the rate of electron transfer between the protein and the metal by several orders of magnitude. The calculation also predicts the switching of electron transfer pathway within the protein depending on the size of the metal cluster. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
