Figure 2.

Typical turbidimetric titration curve for bindings between β-lactoglobulin (BLG) and positive charged magnetic nanoparticles at I = 5 mM. Grey, blue, and pink areas indicate the absence of interaction, selective complexation, and coacervation stages, respectively. Inset image is the enlarged local version for identification of the second stage, as well as pH_c. The data was taken from the work of [40] and the figure was replotted.
