Spin valve sensors for ultrasensitive detection of superparamagnetic nanoparticles for biological applications

We present giant magnetoresistance (GMR) spin valve sensors designed for detection of superparamagnetic nanoparticles as potential biomolecular labels in magnetic biodetection technology. We discuss the sensor design and experimentally demonstrate that as few as ∼23 monodisperse 16-nm superparamagne...
