TEHRAN (INIC)- Researchers at Tarbiat Moallem University of Azarbaijan, Iran, presented a method for the measurement of uric acid in biological samples, which has a higher sensitivity and a lower detection point compared to the current methods.

“Inventing an electro-analysis method for the measurement of uric acid in biological liquids was one of the objectives of this research,” Biyouk Habibi, a member of the Scientific Board of Tarbiat Moallem University of Azarbaijan, told the news service of Iran Nanotechnology Initiative Council.

“The present research has a higher sensitivity and a lower detection point in comparison with the researches carried out recently in this regard, and it is applicable in the measurement of biological liquids,” he added.

According to Dr Habibi, the stages of this research include the synthesis of carbon-ceramic electrode and the study of its electrochemical properties, the modification of its surface with carbon nanotubes and the study of its electrochemical properties, the study of its stabilization and other characteristics, the electro-catalysis of uric acid on the surface of the electrode modified with carbon nanoparticles, the optimization of the parameters related to the catalysis process, the invention of electro-analysis methods for its measurement, and finally, the application of the invented methods in the measurement of uric acid in biological liquids such as urine.

Habibi succeeded in presenting a differential pulse voltammetric electro-analysis method in order to measure uric acid with a proper detection point. He could measure more accurately the amount of uric acid in urine and other samples with the help of this method.

The research has been published in Microchim Acta, vol. 169, pp. 313-320, 2010.
