摘要

生物阻抗谱是一种潜在的技术，可以根据生物材料在频率可变电场作用下的电学特性变化来区分健康组织和患病组织。本文应用该技术测量了健康小鼠的五种不同组织和两种肿瘤细胞系UT-SCC-5(舌鳞状细胞癌)和UM-SCC-10A(喉鳞状细胞癌)的阻抗。结果表明，不同组织类型的阻抗值存在显著差异。更有趣的是，这两个癌性肿瘤的电导率值最高，或者说阻抗值最低。

Bioimpedance Spectroscopy for Characterization of Healthy and Cancerous Tissues

Bioimpedance spectroscopy is a technique that can potentially be used to differentiate healthy from sick tissues based on the variation of electrical properties of biological material when submitted to frequency variable electric fields. In this paper, the technique was applied to measure the impedance of five different tissues of a healthy mice and two cancerous infected with the tumor lines UT-SCC-5 (tongue squamous cell carcinoma) and UM-SCC-10A (laryngeal squamous cell carcinoma). Results show that the different tissue types show a significant variation in their impedance values. More interestingly is that the two cancerous tumors have the highest conductivity values, or equivalently the lowest impedance values.
