Due to the adverse effects of Florfenicol on humans, researchers at the Institute developed a novel method to detect and measure it in milk using optical sensors.
"The easiest way to identify antibiotic residues in milk is to use diagnostic kits, which are qualitative methods," said Dr. Moslem Jahani, the research project supervisor. He also added “Quantitative measurement requires the use of instrumental methods such as chromatographic techniques, which are time-consuming and expensive.
Regarding the results of this research-applied project, Dr. Jahani said: "In this research, a new sensor for measuring Florfenicol in milk samples was presented. Carbon dots are used to make this sensor, which are characterized by strong and stable fluorescence emission. Also, to improve the selective performance of the sensor, the surface of carbon nanoparticles is modified with a layer of molecularly imprinted polymer, which causes the Florfenicol molecules to be selectively adsorbed, reducing the potentially interfering effect of other species.
