Fig. 5 (A) Sensogram, at y ¼ 63.3 , showing the reflectance changes obtained upon to the analysis of
RDX on the Kemp's acid-imprinted bis-aniline-cross-linked Au NPs matrix. RDX concentrations
analyzed: a ¼ 0Mandb-f:12fM-2pM.The inset presents the derived calibration curve for the
different RDX concentrations. (B) Comparison between the calibration curves obtained for the analysis
of variable concentrations of RDX on: ( a ) The Kemp's acid-imprinted Au NPs composite, and ( b )the
cyclohexane tricarboxylic acid-imprinted Au NPs composite. The inset shows the lower concentration
region of the calibration curves. All measurements were performed in a 0.1 M HEPES buffer solution
