Figure 2.
Effect of incubation time on the loading capacity of CaPS and CaPL nanoparticles for (a) bovine serum albumin (BSA); and (b) bradykinin (pH 7.4, particle concentration 500 μg/mL, BSA/bradykinin concentration 500 μg/mL). Both BSA and bradykinin rapidly adsorb on the nanoparticles’ surface during the first hour.
