Highly Synergistic Sensor of Graphene Electrode Functionalized with Rutile TiO Microstructures to Detect L-Tryptophan Compound.

Electrochemical processes are an effective method for detecting dangerous food ingredients. The synergistic between the reduction-oxidation (redox) processes inspired several papers and spurred research towards studying the new materials that can further adapt to optimize the rapid detection of chemical compounds. In this study, we report the eco-synthesis using graphene/TiO rutile (G/TiO) electrode microstructures easily prepared through the physical method by mixing graphene and TiO powder and its application for sensing L-tryptophan (Trp) compound.
