The current techniques for cell cutting always use a diamond knife with an edge angle larger than 20°. The compression caused by the edge angle may destroy the sample. In this paper, a nano knife with a small edge angle 5° was fabricated from a commercial AFM cantilever by FIB etching. The mechanical character of the nano knife was calibrated by theoretical calculation, numerical simulation and nanorobotic...
This paper presets the assembly of a nanowire probe pH sensor and evaluation inside acid and alkali. An AFM cantilever was used for electrodes of the device and etched by FIB. Two carbon nanotubes (CNT) were assembled to the separated electrodes of AFM cantilever. A tungsten probe is etched by focused ion beam (FIB) into 300 nm in diameter and 25 in length. Then the probe is coated by parylene and...
Cell-cell adhesion force is important for cell activities. In this paper, a novel cell-cell adhesion force measurement method using nano picker was proposed based on the nanorobotic manipulation system inside an environmental scanning electron microscopy (ESEM). The nano picker was fabricated from atomic force microscopy(AFM) cantilever by focused ion beam(FIB) etching. The spring constant of the...
This paper presets the assembly of a nanowire probe pH sensor. An AFM cantilever was used for electrodes of the device and etched by FIB. Two carbon nanotubes (CNT) were assembled to the separated electrodes of AFM cantilever. A tungsten probe is etched by focused ion beam (FIB) into 300 nm in diameter and 25.4 μm in length. Then the probe is coated by parylene and cut the tip to open the tungsten...
This paper presets the assembly of a functional device with double metal nanowire. A PZT cantilever was used for electrodes of the device and etched by FIB. Two carbon nanotubes (CNT) were assembled to the separated electrodes of PZT cantilever. A tungsten probe is etched by focused ion beam (FIB) into 300 nm in diameter and 25.4 ??m in length. Then the probe is coated by parylene and cut the tip...
