同轴原子力显微镜镊子
Coaxial Atomic Force Microscope Tweezers
摘要：
我们展示了同轴原子力显微镜（AFM）镊子，可以捕获和放置小物体使用介电泳（DEP）。通过在中心导体和接地屏蔽之间施加射频电压，在同轴AFM探针的尖端处产生吸引力;通过测量拉脱力与施加的电压，发现力的起源是DEP。我们表明，同轴AFM镊子（CAT）可以通过拾取指定的二氧化硅微球，在针尖的末端与微球成像，并将其放置在目标目的地进行三维组装。
英文摘要：
We demonstrate coaxial atomic force microscope (AFM) tweezers that can trap and place small objects using dielectrophoresis (DEP). An attractive force is generated at the tip of a coaxial AFM probe by applying a radio frequency voltage between the center conductor and a grounded shield; the origin of the force is found to be DEP by measuring the pull-off force vs. applied voltage. We show that the coaxial AFM tweezers (CAT) can perform three dimensional assembly by picking up a specified silica microsphere, imaging with the microsphere at the end of the tip, and placing it at a target destination.
