Magnetic nanoparticle biosensors
WIREs Nanomedicine and Nanobiotechnology, 2010AbstractOne of the major challenges in medicine is the rapid and accurate measurement of protein biomarkers, cells, and pathogens in biological samples. A number of new diagnostic platforms have recently been developed to measure biomolecules and cells with high sensitivity that could enable early disease detection or provide valuable insights into ...

Magnetic impedance biosensor: A review
Biosensors and Bioelectronics, 2017Though the magnetoimpedance effect was discovered two decades ago, the biomedical applications of the magnetoimpedance sensor are still in their infancy. In this review, the authors summarized the magnetoimpedance effect in soft ferromagnetic wires, ribbons and thin films for biosensing applications.

Magnetic Biosensors—From Molecule to System
AIP Conference Proceedings, 2008Biosensors research combines molecular-level with system-level challenges. The molecular challenge is to rapidly and reliably detect very low concentrations of molecules in a complex biological sample. The system challenge is to find principles that enable the integration of a series of process steps in a disposable cartridge.

External-field-free magnetic biosensor
Applied Physics Letters, 2014In this paper, we report a magnetic nanoparticle (MNP) detection scheme without the presence of any external magnetic field. The proposed magnetic sensor uses a patterned groove structure within the sensor so that no external magnetic field is needed to magnetize the MNPs. An example is given based on a giant magnetoresistance (GMR) sensing device with
