Figure 5: Adsorption of serum proteins on different NPs: Specific enrichment (log Q > 1) or depletion (log Q < 1) of proteins expressed as logarithm of ratio Q (Q = mass fraction protein x on particle/ mass fraction protein x in serum). Only proteins which differ between the four NPs regarding their enrichment and depletion are plotted. (Abbreviations for the specific proteins are found in the SI.)
