Properties of coronas that form around NP-Ab in HS. (a) DLS of NP-Ab in water (black), PBS (blue), BSA (pink), and HS (orange). (b) DLS of NP-Ab with preformed coronas in water (black), PBS (blue), BSA (pink), and human serum (orange). (c) Zeta potential measurements of NP-Ab in PBS, BSA, and HS (gray) and NP-Ab with preformed coronas in PBS, BSA, and HS (black). (d) DLS of NP-Ab exposed to HS as a function of time. (e) Zeta potential of NP-Ab exposed to HS as a function of time.
