The facility for Development of Functional Materials, a research facility financed by FAPESP and housed within the Federal University of São Carlos, designed the gadget that combines magnetic fluorescent nanoparticles.

In the Journal of Molecular Liquids, researchers from the Center for Development of Functional Materials (CDMF) report on the creation of a sensor that can identify metronidazole in both the environment and living things. An antibiotic called metronidazole is used in both human and veterinary medicine. This medication can build up in the body and cause a number of health issues, so it’s important to keep an eye on its levels in milk, meat, water, and blood, among other places.

The sensor was designed to combine a non-imprinted reference composite with magnetic fluorescent multi-functional molecularly imprinted polymers (MFMIP). Water sample tests revealed strong sensitivity as well as useful benefits including ease of handling and the potential for real-time analysis.

The Federal University of São Carlos (UFSCar) serves as the site of CDMF, one of FAPESP’s Research, Innovation, and Diffusion Centers (RIDCs).

The São Paulo Research Foundation (FAPESP) is a public organization whose goal is to promote scientific research in all domains of knowledge by giving grants, scholarships, and fellowships to researchers associated with São Paulo State’s higher education and research institutions. FAPESP is aware that collaborating with the world’s top experts is the only way to do the greatest research possible. Consequently, it has formed alliances with funding agencies, universities, businesses, and research groups in other nations renowned for the caliber of their work, and it has been motivating scientists supported by its funds to expand their global cooperation.
