In this work, a new modeling approach is presented to obtain a two-dimensional transport lattice of a biological cellular system for the calculation of the potential distribution throughout the system and investigation of the corresponding membrane electroporation. The presented model has been obtained by a modified bilayer model of the cell membrane. This modified membrane model allows for an effective inclusion of the shape of the cell membrane in the potential calculation. The results of the model have shown good agreement with the results of the well-known Schwan equation and COMSOL Multiphysics for the circular cell. The simulation results show that both membranes of a mitochondrion can be simultaneously electroporated by an alternating voltage source with frequencies between 1 MHz and 1 GHz.
在这项工作中,提出了一种新的建模方法,以获得生物细胞系统的二维传输晶格,用于计算整个系统中的电位分布以及研究相应的膜电穿孔。所提出的模型是通过对细胞膜的双层模型进行修改而获得的。这种修改后的膜模型允许在电位计算中有效地纳入细胞膜的形状。该模型的结果与圆形细胞的著名施万方程和COMSOL Multiphysics的结果显示出良好的一致性。模拟结果表明,线粒体的两层膜可以被频率在1 MHz至1 GHz之间的交流电压源同时电穿孔。
