内容記述 |
Diamond quantum magnetometers (DQMs) based on negatively charged nitrogen–vacancy (NV) centers in diamond are promising tools for biomedical applications. Their high sensitivity under ambient conditions at room temperature enables a reduced standoff distance from the measurement object such as the brain in magnetoencephalography (MEG). We developed a sensitive DQM with a sensitivity of 6 pT Hz-1/2, aiming at MEG applications in living rats and humans. The sensor is compatible with MEG measurements and allows a minimum standoff distance of about 1 mm. We evaluated its performance in practical MEG measurements using a phantom. In addition, we attempted measurements of an evoked field in rats. We will discuss recent progress in improving the sensitivity of our DQM and in applying it to biomagnetic sensing. |
