Fig. 7From: Synthesis, characterization, and biological studies of some biometal complexesa Fluorescence quenching curves of ethidium bromide bound to DNA in presence of Ni (II) complex. b Stern-Volmer plots of the fluorescence titration for Ni (II) complex. Representation of slope and Intercept values. Kb = slope/Intercept value i.e. 1.94 × 102M-1 F0 = Highest emission of DNA+Etbr, F = Highest emission of DNA+Etbr after addition of complexesBack to article page
