Iran designs nano-sensor to measure food colorings in foodstuff

TEHRAN (ISNA)-Iranian researchers at Tabriz University, northwestern Iran, have designed and built a nano-sensor capable of measuring food colorings in a selective, sensitive and simultaneous way.
Reza Fadakar, a PhD student in Analysis Chemistry in the university and lead author of the project, said the nano-sensor is made of Carbon ceramic and has been modified by multi-walled Carbon nano-pipes. The modified sensor is of high selection capability and sensitivity comparing to the intended samples.

He also expressed the hope that the method could be used in laboratories to control the exact level of the colorings in foodstuff.

The results of the study have been published in Food Analytical Methods Journal.
