Cell stimulation using direct vibration with magnetic beads and development of a measurement system

为了研究细胞功能在振动刺激下的表达，建立了一种将直径为几微米的磁珠附着在细胞壁上直接振动的细胞刺激系统。磁珠在交变磁场作用下振动，振动幅值由新研制的光学系统测量。磁珠的最大振动幅值为451nm，激励频率为80hz。

Cell stimulation system using direct viblation with magnetic beads, which has a diameter of several micro meters, attached on the cell wall has been developed to investigate the expression of cell function with the vibration stimuli. The attaced magnetic beads are vibrated with an alternating magnetic field and the vibration amplitude is measured by newly developed optical system. The magnetic beads were vibrated with maximum oscilation amplitude of 451 nm with a excitation frequency of 80 Hz.
