| Outline of Final Research Achievements |
To detect cell healthies, mass and radical density of cell is an important role to monitor cell’s states. To measure the radical density in cell, the force measurement system is useful by detecting electron magnetic resonances. For higher sensitivity in air, vacuum packaged magnetic sensors and diamond nitrogen vacancy (NV) center on Si probes have been developed. The magnetic sensor showed the detectable magnetic field of 2.4×10-10 T. The probe with NV center is usable for magnetic detection using optical methods based electron magnetic resonance. To measure the mass changes of cell, an assembled micro-tube resonator for mass sensing in liquid is fabricated and evaluated. Flowing liquid is injected as the evaluation of mass change detection performance of the device. Self-oscillation experiment has been used for recording actual mass change based on the resonance frequency shift with flowing liquid. Minimum mass resolution of the device is in the value of 1.04 pg.
