Abstract We developed a novel magnetometer that employs negatively charged nitrogen-vacancy (NV − ) centers in diamond, to detect the magnetic field generated by nanoparticles (MNPs) for biomedical applications. The compact probe system is integrated into fiber-optics platform allowing design. To signals from MNPs effectively, we demonstrated, first time, application of an alternating current (AC) excitation coil several hundred microteslas magnetization diamond quantum sensing. In lock-in...
We have developed the magnetic probe with a diamond quantum sensor and electromagnetic coils to detect sentinel lymph nodes (SLNs), as medical application of sensing. The magnetizes nanoparticles (MNPs) accumulated in SLNs fields magnetized MNPs. In this study, we designed ferromagnetic core that has unique shape optimized field generation system for improving detection performance such sensitivity detectable distance. proposed enhances an excitation strength at longer distance suppresses...
