In order to investigate the changes observed in the steric stability of
AgNP-GAL, the Wh/2 evolution was determined over time (Fig. S6c). At
[NaCl] b 153 mM, the Wh/2 values were lower than those observed in
the absence of salt. Moreover, a decrease over time was observed for
[NaCl] b 60 mM during the first 10 s of the experiment.
