Abstract:
Iranian chemists from the University of Tabriz produced a simple and cost-effective nanosensor by using gold/silver nano alloy in order to measure the melamine in the powder milk for infants.

Iranian Scientists Fabricate Melamine Nanosensor

Tehran, Iran | Posted on September 1st, 2012

"Among chemiluminescence systems, only a few possess the desirable emission intensity and the necessary sensitivity for carrying out the analyses. A chemical catalyst is usually used in order to increase the performance. According to the researches, most of metallic and metallic oxide nanoparticles have high catalytic activity and therefore, they strengthen chemiluminescence signal," Dr. Jamshid Manzouri Lashkar, one of the executors of this project, said.

"Permanganate chemiluminescence systems do not have enough intensity for analysis in normal conditions. We tried in this project to increase the intensity of the system by using an appropriate catalyst. Studies showed that nanoparticles, especially gold and silver nano alloys, have significant increasing effect on the intensity of chemiluminescence systems," he added.

Dr. Manzouri Lashkar talked about one of the most important objectives of this research, and stated, "Protein measurement method in nutritious materials is done according to their nitrogen percentage. Since melamine has high percentage of nitrogen in its structure, some producers add illegally melamine to the food of pets and to powder milk for infants so protein percentage increases in those materials. In this research, we tried to present a simple and sensitive method for the measurement of melamine in those materials. We achieved our goal by using melamine accumulation with the synthesized nanoparticles."

Results showed that gold/silver nano alloys have higher catalytic activity than nanoparticles made of pure gold or silver, and they can be used in the precise measurement of melamine at low concentrations in powder milk for infants.
