“…Given that NP-protein adsorption is highly selective and is influenced by their own physicochemical properties of both the proteins and the NPs [9,11,12,28,32,33], we first designed and synthesized a panel of zeolitebased NPs with different physicochemical characteristics, including M086 (NaY, Si/Al = 2.6), M158 (CHA, Si/ Al = 2.0) and M909 (FAU, Si/Al = 2.0) (Additional file 6: Table S1). We then evaluated the adsorption capacity of these NPs and relationship between concentration of NPs for plasma proteins (Additional file 1: Fig S1A ) by SDS-PAGE [37]. Our results showed that all three NPs reduced the dynamic range of plasma proteins and different concentration of NPs hardly changed the pattern of absorbed protein, especially above 0.5 mg ~ 200 mL.…”
