Core-shell Fe3O4@Ag magnetic nanoparticles detection using spin-valve GMR sensing element in the wheatstone bridge circuit

Core–shell Fe _3 O _4 @Ag magnetic nanoparticles (MNPs) integrated with a Wheatstone bridge-giant magnetoresistance (GMR) sensor provide access to GMR-based biosensors. The Fe _3 O _4 nanoparticles synthesized using the coprecipitation method demonstrated 77 emu g ^−1 of magnetization saturation ( M...
