A comprehensive understanding of the transportation of Zn -diamsar in blood will be beneficial for the investigations in drug design and toxicology. Hence we hereby investigated thebinding interaction of Zn -diamsar with serum albumin in physiological buffer solution (pH 7.4) at 298 K by fluorescence spectra. It was proved that Zn -diamsar quenched the intrinsic fluorescence of Serum albumins by forming a complex between them. The binding constant (K) were calculated using the modified SterneVolmer equation
