- Advances in Giant Magnetoresistance Biosensors With Magnetic Nanoparticle Tags: Review and Outlook (2008, methodology): “Here, the peak-to-peak resistance change of SV sensors before and after capturing magnetic nanoparticle tags is defined as the signal [2], [18], [33], which is proportional to the signal voltage at a given sense current.”
- Magnetoresistive-based biosensors and biochips. (2004, methodology): “The majority of labels that have been used to date have been iron-oxide (magnetite or maghemite)-based, although transition metal containing nanoparticles (for example, NiFe or CoFe) offering higher magnetisation are now being studied [ 14 ].”
- Magnetic bead handling on-chip: new opportunities for analytical applications (2004, background): “Theoretical modeling showed that a GMR sensor can detect a single superparamagnetic bead of any size (Tondra et al. 2000; Li et al. 2003; Li and Wang 2003), as long as all system dimensions (bead size, sensor size, distance between bead and sensor) scale down proportionally.”
