Researchers at the University of Central Florida (UCF) in the US are combining nanoscience with the principle of Faraday rotation, a magnetic phenomenon discovered in 1845, in a new method for speedy medical tests.
The team applied the magneto-optical technique, called frequency-domain Faraday rotation spectroscopy—or fd-FRS, to characterize proteins, using antibody-functionalized magnetic nanoparticles (MNPs).
“Fd-FRS is a new way of looking at the interaction between light and magnetized material,” says Shawn Putnam, assistant professor UFC’s College of Engineering & Computer Science. “We covered the surfaces of magnetic nanoparticles with a layer of biological sensors and measured their movement after exposure to their corresponding biological targets for detection.”
