Carbon Nanotubes Detect Cysteamine in Biological Compounds

Iran | Posted on December 31st, 2009

Nanotechnology has opened new horizons for the use of nanoparticles and carbon nanotubes in analytical chemistry and detection of some biological and chemical compounds. One of the interesting applications of nanoparticles and carbon nanotubes is to facilitate electron transfer reactions.

"Since some of amino acids are sulfuric compounds, their electrochemical oxidation on the surface of common electrodes are very slow. As a consequence, we can't detect them on the current electrodes surfaces and measure," Fereshteh Chekin, one of researchers, said to Iran Nanotechnology Initiative Council (INIC).

To overcome this limitation, different mediums were utilized and modified chemical electrodes were made. In this regard, the researchers fabricated modified glassy carbon electrode by means of functionalized carbon nanotube to electrochemically measure cysteamine.

The stabilization of electron transfer mediums like carbon nanotubes and naphthoquinone compounds on electrode beds was characterized by SEM images. This naphthoquinone functionalized modified electrode was used as an electrochemical sensor in voltammetric measurement of cysteamine.

"The present study is a fundamental research which could be used in the measurement of cysteamine present in biological specimens at clinical laboratories and research centers", Chekin added.
