TEHRAN- Iranian Researchers in University of Mohaqeq Ardeabili have designed a biosensor using nanoparticles for detecting food spoilage, ISNA reported on Monday. 

According to Dr. Mandana Amiri, a member of the research team, the sensitive superoxide biosensor is based on silicon carbide nanoparticles and can detect bacteria in food.

The nanobiosensor can spot harmful bacteria in food both quickly and precisely, while it would have a low price as a fast, cost-effective method was used for its development, she explained.

In this method, uropathogenic E. coli cells were entrapped into ultra-thin sol-gel matrices on gold thin films, she added.
