Applications and Nanotoxicity of Carbon Nanotubes and Graphene in Biomedicine
Figure 4
(a) Schematic of graphene as a SERS substrate. Graphene as a SERS substrate for Rhodamine 6G detection using (b) 514.4 nm laser and (c) 632.8 nm laser. The blue line is a SiO2/Si substrate and the red line is graphene. Note that (a–c) reproduced with permission from [187]; (d) a quasi-linear arrangement of Au nanoparticles on vertical graphene nanosheets (VGNs); SERS spectra of 10−2 m 4-aminothiophenol on (e) Au-VGNs array, (f) VGNs only, and (g) Au nanoparticles only. Note that (d–g) reproduced with permission from [188].
