Graphene Electrode Used for Drug Measurement

Tehran, Iran | Posted on May 25th, 2011

"Considering the electronic characteristics of graphene such as very high conductivity, vast surface area, and very high rate of electron transfer, we used this material to produce a new generation of electrodes," Mohammad Hadi Parvin, one of the researchers of this project, said.

"My main objective was to produce a graphene paste electrode and to use it in drug measurement. Luckily, I reached my goal and the results were published in Electrochemistry Communications, vol. 13, pp. 366-369, 2011," Parvin said about the objectives of the research.

"The production of ultra-intelligent drug carriers and the production of graphene anodes to be used in steel industry were among the other objectives of this project. The sensor produced in this research is capable of being used in the both abovementioned fields."

Elaborating on the steps to produce this electrode, he continued, "I firstly converted graphite to graphene oxide through the methods mentioned in the paper, then I reduced the graphene oxide to graphene by using a reducer. In the end, I purified it through washing and extraction methods, and dried the obtained product. Next, the graphene was powdered and I produced the electrode from the graphene paste."

"This electrode has many applications in medical industries, pharmacology, petroleum industry (for studying the corrosion in reservoirs and pipelines), agricultural industry, and steel industry," Parvin concluded.
