FESEM readily dispersed and aggregated states of GNP and GNR. a The scanned image showing the peaks of respective molecules in dispersion condition. Figure inset displays FESEM image. b The scanned image showing the peaks of respective molecules in aggregated condition. Na and Cl could be seen only with the aggregated state. Figure inset displays FESEM image. c Image showing GNR in dispersion. d Image showing GNR in aggregation. One optical density of GNP has been used
