Magneto-Optic Biosensing for Medical Diagnostics: Advances in Nanoparticles, Biomarkers, and Point-of-Care Applications

Magneto-optic biosensors are emerging as promising tools for sensitive medical diagnostics. These sensors exploit magneto-optic effects, particularly the Faraday effect, to convert magnetic changes in functionalized nanoparticles into measurable optical signals. The integration of magnetic and magnetoplasmonic nanoparticles enables the detection of important biomarkers associated with cancer and neurological diseases. This paper reviews the fundamental principles and biomedical applications of magneto-optic biosensors, with emphasis on biomarker detection, Alzheimer’s disease diagnosis, and point-of-care systems. The main advantages, challenges, and future prospects of this technology are also discussed.
