摘要

本文介绍了用直流静电力显微镜测定单个红细胞及其膜的静态介电常数的结果。该方法是基于对实验静电图像横截面的定量分析。提出了悬臂顶端与圆盘状生物细胞之间静电相互作用的模型。所得的单个红细胞的介电常数与已发表的数据吻合得很好。通过有效介质近似计算红细胞的介电常数，并与我们模型的红细胞介电常数平均值进行比较。

Determination of the Static Permittivity of Individual Red Blood Cells and Their Membranes by Electrostatic Force Microscopy

The results of determination of the static permittivity of individual red blood cells (RBCs) and their membranes by dc-electrostatic force microscopy are presented. This method is based on a quantitative analysis of the cross-sectional profiles of experimental electrostatic images. A model of electrostatic interaction between the cantilever tip and a biological cell of disk shape is proposed. The obtained permittivity of individual RBCs agrees well with published data. Calculation of the permittivity by the effective medium approximation for RBCs is performed for comparison with the mean value of the RBC permittivity of our model.
