SW-4-2-1: Micro-Nano Manipulation and Control for Biological Analysis

Prof. Toshio Fukuda, Nagoya University, Japan

Abstract

Micro-nanomanipulation and control techniques have been widely used for various academic and industrial applications. Recently, we proposed single cell nanosurgery system based on the single cell analysis techniques with local manipulation and control using various micro-nano tools. The proposed techniques can realize the single cell diagnosis, extraction, cutting, injection and embedding of micro-nano devices. For example, we developed a novel oscillating nano knife for single cell cutting. The nano knife with a small edge angle 5ยบ was fabricated at the end of cantilever. The spring constant of the nano knife was calibrated by theoretical calculation and nanorobotic manipulation methods respectively. A piezo actuator was employed to generate the vibration of the nano knife. The oscillating amplitude response to the applied voltage was calculated based on the real-time image observation. Single yeast cell cutting using oscillating nano knife was performed based on the nanorobotic manipulation system inside an Environment-SEM (E-SEM). The maximum cutting forces and the slices angle were measured from the deformation of the nano knife beam and the single cell. The result showed the oscillating nano knife was capable and effective for single cell cutting task.
