Abstract
A biosensor is described. The biosensor includes a fixed multilayer stack providing a magnetization oscillation, a voltage source electrically coupled to the fixed multilayer stack, and a binding molecule covalently bonded to the biosensor. The voltage source provides a direct current through the fixed multilayer stack to generate the magnetization oscillation and a target molecule including a magnetic nanoparticle forms a complex with the binding molecule and alters the magnetization oscillation.
