The proposed project is to develop a method to directly measure the nanometer-scale fluid velocity in order to characterize the flow field in the vicinity of cell-surface mechanoreceptors. The method is based on use of the atomic force microscopy (AFM) to access the small scale regions on the cell surface. The AFM cantilever tip is modified by placing nanocarbon bundles with a single nanocarbon tube protruding into the flow field. The force on the nanocarbon tube will be correlated to the flow filed to extract the flow velocity information.

该项目旨在开发一种直接测量纳米级流体速度的方法，以表征细胞表面机械感受器附近的流场。 该方法是基于使用原子力显微镜（AFM）访问细胞表面上的小尺度区域。 通过将纳米碳束与突出到流场中的单个纳米碳管一起放置来修改AFM悬臂尖端。 将纳米碳管上的力与流场相关联，以提取流速信息。
