Figure 1From: Facile and green reduction of covalently PEGylated nanographene oxide via a ‘water-only’ route for high-efficiency photothermal therapyAFM characterization. (A) AFM images of GO, nGO, nGO-PEG, and nrGO-PEG. AFM histograms of (B) diameter and (C) thickness for GO, nGO, nGO-PEG, and nrGO-PEG. The diameter was assumed to be in round shape.Back to article page
