Determination of ruthenium on DNA by XRF [PDF]
Biological Trace Element Research, 1987 An X-ray fluorescence (XRF) technique is used to quantitate the binding of [H2O(NH3)5Ru(II)](2+) to DNA. This method is shown to be more sensitive, precise, and convenient than conventional optical absorption (OA) spectroscopy, differential pulse voltammetry (DPV), or atomic absorption (AA) techniques. X-ray fluorescence is insensitive to the oxidation
