Simultaneous binding of ruthenium(II) [(1,10-phenanthroline)(sub 2)dipyridophenazine](super 2+) and minor groove binder 4',6-diamidino-2-phenylindole to poly[d(A-T)(sub 2)] at high binding densities: observation of fluorescence resonance energy transfer across the DNA stem

Article Abstract:

The circular dichroism (CD) and the linear dichroism (LD) spectral properties of the enantiomers of [Ru(phen)(sub 2)DPPZ](super 2+) which is bound to poly[d(A-T)(sub 2)] in the presence or absence of an established minor groove binding drug is studied. It is suggested that the excitation energy of DAPI is transferred to the metal complex across the DNA stem.

Epitaxial growth of RuO2(100) on Ru(1010): surface structure and other properties

Article Abstract:

The techniques of low-energy electron diffraction (LEED) and density functional theory (DFT) calculations were used for determining the structure of RuO2(100) formed on Ru(1010). The growth of a RuO2(100) film may be caused due to the oxidation of the Ru(1010) surface.
