Intensity-weighted average hydrodynamic diameter for core-shell nanoparticles with different adsorbed macromolecules in PBS. (a) Extensive aggregation is evident with PEG 6k, PEG10k, and PEG100k, while (b) bovine serum albumin (BSA), dextran, Pluronic F127, and Pluronic F68 provided stable hydrodynamic diameters over the course of 5 days. ‘Day 0’ corresponds to the start of the overnight adsorption of macromolecules to the MNPs.
