(A) Evaluation of the conjugation of 12F6 antibody at different concentrations on AuNPs at pH 7, 8 and 9 by means of the variation of absorbance (ΔAbs.) caused by the addition of NaCl and (B) the corresponding coefficient of variation (CV, %) of each point. (C) Evaluation of the linearity of the color decrease related to U(VI) concentration for LFs at different concentrations of DCP.
