本研究的重点是尿酸晶体的磁性行为，这是负责痛风。在亚特斯拉（T）级磁场下，观察到晶体的旋转运动，这是由抗磁扭矩引起的。我们使用由电磁铁产生的最大幅度为500 mT的水平磁场，通过显微镜观察尿酸微晶的磁取向。尿酸晶体显示出垂直磁场取向，最小阈值为130 mT。我们推测尿酸晶体中明显的抗磁各向异性导致了它们的转动响应。
The present study focuses on the magnetic behavior of uric acid crystals, which are responsible for gout. Under a sub-Tesla (T)-level magnetic field, rotational motion of the crystals, which were caused by diamagnetic torque, was observed. We used horizontal magnetic fields with a maximum magnitude of 500 mT generated by an electromagnet to observe the magnetic orientation of the uric acid microcrystals by a microscope. The uric acid crystals showed a perpendicular magnetic field orientation with a minimum threshold of 130 mT. We speculate that the distinct diamagnetic anisotropy in the uric acid crystals resulted in their rotational responses.
