| 目的：以小鼠成骨细胞为材料，建立一套完整的用于成骨细胞的介电特性检测方法。方法：本研究首先是设计制作不同形状
和尺寸的细胞介电谱检测装置（测量池），其次进行测量池的生物相容性评价，包括浸提液毒性实验，HE 染色观察细胞形态。最后
将细胞培养在测量池中，连入阻抗分析仪在20Hz~10MHz 检测并联电导Gp 和电容Cp 并绘制介电谱图。结果：生物相容性检测
表明测量池对细胞无毒性，可使用。此外，介电特性检测结果表明随着频率的增大，细胞的电容减小，电导略微增大后减小；随着
培养时间的增长，电容值增大而电导值减小；经中强磁场处理后，细胞的电容和电导值都有下降。结论：该方法能够为其他贴壁细
胞的介电特性检测提供研究基础，并对于在此基础上展开的贴壁细胞介电特性解析提供参考。 |

| Objective:To establish a complete set of dielectric properties detective method for osteoblast by using mouse osteoblast.Methods:Different shape and size of cell dielectric spectroscopy detection device (dielectric cell) was designed and made, and
the biocompatibility, including the toxicity test of leach liquor, HE staining was measured to observe the cell morphology. The cell were
cultured in the measuring vessel, parallel conductance Gp and parallel capacitance Cp in 20Hz~10MHz was detected by impedance analyzer
and draw the dielectric spectra.Results:Biocompatibility testing showed that the dielectric cell had no toxicity to cell and it can be
used. Dielectric properties detection results showed that with the increase of frequency, the capacitance decreased, conductance slightly
increased and then decreased. With the growth of the culture time, the Cp and Gp values all decreased. Moderate intensity magnetic field
treated showed that the Cp and Gp values all declined.Conclusion:This method can provide a research bases for other dielectric property
detective of adherent cells, and it can also provide a reference for adherent cells analysis based on this method. |
