Abstract
We describe hopping mode scanning ion conductance microscopy that allows noncontact imaging of the complex three-dimensional surfaces of live cells with resolution better than 20 nm. We tested the effectiveness of this technique by imaging networks of cultured rat hippocampal neurons and mechanosensory stereocilia of mouse cochlear hair cells. The technique allowed examination of nanoscale phenomena on the surface of live cells under physiological conditions.
摘要
我们描述了跳变模式扫描离子电导显微镜，它能够对活细胞复杂的三维表面进行非接触成像，分辨率优于20纳米。我们通过对培养的大鼠海马神经元网络和小鼠耳蜗毛细胞的机械感觉静纤毛进行成像，测试了该技术的有效性。该技术能够在生理条件下检测活细胞表面的纳米级现象。
