Figure 4. Micrographs of functionalized and immobilized graphene nano sheets.

Figure 4

(A) Transmission Electron Micrograph (TEM) images of functionalized (a) and coupled (b) graphene showing fine transparent sheets with inset showing the characteristic Selected Area electron Diffraction pattern (SAD). Functionalized graphene sheets appear transparent whereas islands of immobilized enzyme can be seen in coupled graphene (B) Scanning Electron Micrograph (SEM) images of functionalized (a) and coupled (b) graphene.
