General description

Graphene oxide (GO) is the solution processable precursor for bulk production of graphene based materials and devices. It is produced by the chemical exfoilation of graphite. GO is amphiphillic in nature, it also forms highly stable emulsions of organic solvents. Chemical modification of GO helps in improving the biocompatibility and solubility of graphene.

Application

Webinar: Graphene-Based Nanomaterials for Versatile Biosensors
Dielectric Materials for Field Effect Transistors (FET); Non-silicon-based materials for integrated circuits (IC). Some proposed applications of GO are:
  • water soluble/insoluble, targeted/untargeted drug and gene delivery applications
  • tissue engineering
  • electrochemical biosensors
  • optical biosensors
  • graphene oxide Langmuir Blodgett films as hole injection layers for organic light emitting diode.
