Supplementary Material

Figure A shows the AA and BSA solutions. The spectra at different concentrations for water (pH adjusted to 7) with aliquot of 40 μL of AA at pH 3 are showed in Figure B. This experiment has been performed in order to rule out the effect of AA. The difference between the spectra of BSA (Figure 1 in the manuscript) and water (Figure B) reveals the behavior of BSA regarding to AA (Figure C).
