Surface morphology of carbon nanomaterials and blood plasma proteins. Representative AFM images of (a) CNT-COOH, (b) GNP, (c) PGO, (d) Albumin, (e) Globulin and (f) Fibrinogen, where: (i) Amplitude images of the nanomaterials and plasma proteins. (ii) 2D height images of the nanomaterials and plasma proteins with (iii) their respective sectional profiles (that is, S1 and S2 in Figure ii). (iv) 3D height images of the nanomaterials and plasma proteins. Scale bars represent 500 nm. AFM, atomic force microscope; CNT-COOH, COOH-functionalized carbon nanotube; GNP, graphene nanoplatelet; PGO, porous graphene oxide.
