Antibody array analysis of human cell membrane receptor (original drafts) in U87 glioma cells (a1–a4) and Hs5 fibroblast cells (b1–b4), with or without 24 h treatment (C: control, a1,b1), with graphene flakes (GN/ExF: a2,b2) and two types of reduced graphene oxides (rGO/ATS: a3,b3; rGO/TUD: a4,b4). The full array map and uncropped images are available in the supplement material. Results were normalized and compared to a dots control sample. The dots with the location (C3, C4) indicate the expression of endoglin (CD105), (F7, F8) indicate uPar (CD87), and (I5, I6) indicate MICA. Abbreviations: rGO, reduced graphene oxide; GN, graphene; C, control group (untreated group); ExF, exfoliation; Term, thermal; ATS, ammonium thiosulphate; TUD, thiourea dioxide; CD105, endoglin; uPar, urokinase plasminogen activator surface receptor; MICA, major histocompatibility complex class I chain-related protein A.
