AbstractWe have demonstrated the use of highly sensitive spin valve sensors for the detection of micron magnetic beads. By using a ring type, cross type, and meander line type sensors, we were able to detect the presence of 2.8 μm size magnetic beads in real time by direct measurement of magnetic dipole fields from magnetic beads. The sensitivity of the ring, cross and meander line sensors were obtained about 50 μV/Oe, 7 μV/Oe, 30 μV/Oe and sensor output signals of 50 μV , 30 μV, 90 μV were obtained in an external applied field of 10 Oe and 1 mA sense current. Our results shows that ring, cross, and meander line shape spin valve sensors are very promising candidates for the detection of biomolecules with magnetic labels.

Theranostic Applications

Magnetic Nanoparticles (MNPs) with theranostic applications have engrossed innumerable attention in breast cancer therapies. Breast cancer is a malignancy that affects numerous women globally and has a bad prognosis. These novel MNP formulations have ultra-small particle sizes, high intrinsic magnetic field characteristic, effective imaging, drug targeting, and drug delivery characteristics. MNP also has anticancer properties as well as imaging and magnetic targeting abilities. Theranostic application of MNP can be used in preclinical and clinical settings, and it could be beneficial in cancer treatment and imaging. Furthermore, if these nanoparticles can be functionalized with antibodies or ligands, they can be used as new platforms in a variety of biological applications. In a nutshell, theranostic application of MNP is a small step in the long fight against breast cancer.
