Studies from Kyoto University Further Understanding of Biological Pigments

February 25, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Biological Factors have been published. According to news reporting originating from Kyoto, Japan, by NewsRx correspondents, research stated, "Electron transfer at metal oxide-organic dye interface on ZnO nanorod (ZnOr) templates was studied by femtosecond absorption spectroscopy method. Further confirmation of the electron transfer was obtained from photoelectrical studies."

Our news editors obtained a quote from the research from Kyoto University, "The fastest electron transfer from zinc porphyrin (ZnP) to semiconductor was observed for ZnOr modified by a 5 nm layer of TiO2 (

According to the news editors, the research concluded: "This indicates that the charge recombination depends mainly on semiconductor bulk properties whereas the charge separation is determined by the organic-semiconductor interface."
