My research interest lies in chemical sensing and the challenges in creating a sensitive, selective, and stable sensor. My initial project investigated the use of gold nanoparticle-decorated graphene for the electrochemical detection of sulfide ions in aqueous media. Single-layer graphene is grown via chemical vapor deposition on copper foil and decorated with gold through galvanic displacement. The gold-decorated graphene is transferred to an inert substrate for electrochemical testing. Characterization is done with Raman spectroscopy, SEM, AFM, and XPS.
