Abstract

This research uses the facile transferral of graphene onto gold interdigitated electrodes (IDEs) such that the adjacent digits of the electrode array form contacts to graphene flakes. Successful transferral is measured using environmental scanning electron microscopy (ESEM) and Raman spectroscopy. Following successful transferral the graphene has been employed as a sensing material in regard to its electrical characteristics. The presence of pyrene butyric acid (PBA) between 5 μM and 50 nM can be measured as a function of graphene electrical resistance. The initial results presented indicate a resistance change of 770 mΩ at saturation. Measurement variability is attributed to the reproducibility of the graphene which is currently being assessed.
