The device, which combines magnetic fluorescent nanoparticles, was designed at the Center for Development of functional materials, a research center supported by FAPESP and hosted by the Federal University of São Carlos.

The device was tested on water samples, showing good sensitivity and ease of handling

Researchers at the Center for Development of Functional Materials (CDMF) describe in the Journal of Molecular Liquids the development of a sensor that detects metronidazole in organisms and the environment. Metronidazole is an antibiotic used in human and veterinary medicine. Accumulation of this drug in the body can result in various health problems, and levels in blood, water, meat and milk, among others, need to be monitored.
The sensor combined magnetic fluorescent multi-functional molecularly imprinted polymers (MFMIP) with a non-imprinted reference composite. Tests on water samples showed good sensitivity and practical advantages such as the possibility of real-time analysis and ease of handling.
CDMF is one of FAPESP’s Research, Innovation and Diffusion Centers (RIDCs) and is hosted by the Federal University of São Carlos (UFSCar).
