Development of a Technique for Nanoscale Resolution of Fluid Velocity Fields with Emphasis on Flows Over Cell-Surface Nanostructures

本项目的目的是开发一种直接测量纳米尺度流体速度的方法，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)来获取细胞表面的小范围区域。对AFM悬臂尖端进行了改进，将纳米碳束与单个纳米碳管突出到流场中。将纳米碳管所受的力与流场进行关联，提取流速信息。

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.
