Adsorption of IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 (P40), IL-12 (P70), IL-13, IL-17, Eotaxin, G-CSF, GM-CSF, IFN-γ, KC, MIP-lα, MIP-1β and RANTES cytokines by PCB5k polymer (white bars), PEG5k polymer (red bars), PCB5k-SCKs (black bars) and PEG5k-SCKs (blue bars). The values are presented as the ratio of concentration of the cytokines in the cytokines/nanoparticles mixture (500 µg/mL polymers or nanoparticles) to that in a solution that contains the same amount of the cytokines but without nanoparticles.
