我们介绍了一种磁力浮力变化（MFBV）技术，采用强烈的不均匀磁场来改变溶液中的细胞和其他抗磁性系统的有效浮力。非游泳的Paramatrium已经暂停，被迫沉积和驱动上升的解决方案，使用MFBV。它们对MFBV的反应的细节已被用于确定单个草履虫的磁化率。还描述了使用MFBV作为无限期悬浮细胞培养物的手段。(C)2004年，美国物理学会。
We introduce a magnetic force buoyancy variation (MFBV) technique that employs intense inhomogeneous magnetic fields to vary the effective buoyancy of cells and other diamagnetic systems in solution. Nonswimming Paramecia have been suspended, forced to sediment and driven to rise in solution using MFBV. Details of their response to MFBV have been used to determine the magnetic susceptibility of a single Paramecium. The use of MFBV as a means by which to suspend cell cultures indefinitely is also described. (C) 2004 American Institute of Physics.
