Chemically modified graphene (CMG) nanostructures with their microscale area, sensitive electrical properties, and modifiable chemical functionality are excellent candidates for biodevices at both biocellular and biomolecular scale.
"Chemically modified graphene" is a tad ambiguous, but adding "nanostructure" is a pleonasm. And calling their area "microscale" is not only wrong, but misleading. Leaving the electrical properties part alone, I can only laugh at "modifiable chemical functionality". "Biodevice" is a somewhat clear concept and yes, graphene has potential applications in the field. But what does "bio" have to do in "biocellular and biomolecular scale"?
Fancy words but not much meaning.
