当磁粒子包裹相应的外层物质时,可以与细胞产生选择性黏附,该特性可用于细胞分离、分选、药物运输等。在硅片上制做导线阵列,通过对相应导线阵列的通断电控制,可以控制微磁粒子运动,也就控制了与其相联的细胞运动。细胞运动到指定位置,借助工具对细胞进行操作,研究细胞特性。讨论导线阵列的MEMS工艺,对通电导线产生的磁场、温度场进行了仿真,了解电磁力大小的影响因素。The magnetic particle according to the outside layer material wrap up,can produce the selectivity with cell to stick to attach,this characteristic can be used for the cell separation,choose separately,the medicine conveyance etc.The electric order of different wires is changed to form a moving micro electromagnetic field,and then the particle movement can be manipulated,and also the cell movement can be manipulated.When the cell reaches the destination,use the tool to manipulate the cell and research the characteristic of the cell.And discussing the MEMS technique of wire array,simulate the magnetic field and temperature field,and know the influence factors on electromagnetic force
