Figure 3: Dynamic light scattering in human serum: ACF and fits of (a) PS-LUT-NH2, (b) PS-LUT and (c) PS-SDS in serum (NP/SPiv) (Table 4). Sample PS-LUT-COOH did not show aggregation in diluted serum (cs,iv = 6 mg•mL-1) (d) but aggregates occurred in undiluted serum (cs,conc = 60 mg•mL-1 and NP/SPconc) (e). Red lines, fit by eq. 1 and the resulting residues; blue lines, fits with eq. 2 and the resulting residues, ■ data points of the ACF. Scattering angle 60°.
