Abstract Scope Glycine is a simple amino acid that crystallizes in three polymorphs- alpha (α), beta (β), and gamma (γ). Among them, stable γ-polymorphs show piezoelectricity when subjected to limited mechanical force. However, the dipoles become scattered when exposed to large mechanical stress leading to no net polarization and hence no piezoelectricity. Our aim was to stabilize the glycine dipoles by attaching them to the surface of graphene oxide. First, we carboxylated the graphene oxide to increase the carboxyl groups i.e., the reaction sites for attaching glycine molecules. Then to activate the carboxyl groups of graphene oxide and attach the glycine molecules to the carboxylated graphene oxide, we employed EDC-NHS Coupling Reaction. FTIR spectroscopy of the samples is required to examine whether the functionalization was successful whereas SEM of the samples would enable us to observe surface morphology and to distinguish the morphological changes due to all the reactions.
