Magnetospirillum gryphiswaldense 是一种具有永久磁矩的趋磁细菌,能够使用两个双极定位的鞭毛游泳。在自然环境中,这些细菌以典型的运行和反转模式沿着均匀地磁场的磁力线游动,从而产生具有尖锐边缘的不可微分轨迹。尽管如此,在当前的工作中,我们通过使用石榴石薄膜的异质磁场,实现了沿着机械不稳定性曲线的稳定引导。细菌的成功引导取决于磁小体链的运动性和磁矩之间的正确平衡。
Magnetospirillum gryphiswaldense is a magnetotactic bacterium with a permanent magnetic moment capable of swimming using two bipolarly located flagella. In their natural environment these bacteria swim along the field lines of the homogeneous geomagnetic field in a typical run and reversal pattern and thereby create non-differentiable trajectories with sharp edges. In the current work we nevertheless achieve stable guidance along curved lines of mechanical instability by using a heterogeneous magnetic field of a garnet film. The successful guidance of the bacteria depends on the right balance between motility and the magnetic moment of the magnetosome chain.
