Abstract

The present invention provides a device and method for moving and rotating a microsphere object. A glass needle placed in water is driven by the vibration of a vibration mechanism to rotate at a highspeed to cause eddy current in the water, and finally the purpose of moving and rotating the microsphere object is achieved. Compared with an existing system which operates a microsphere object by a micromanipulator, the device has the advantages that the mechanical contact with the microsphere object is not needed, the direct or indirect damage to the microsphere object is avoided, an end of theglass needle can continuously rotate the microsphere object in an original place, the microsphere object is easily controlled within the field of view, and the observation is convenient. Compared withan existing system for operating a microsphere body in a micro-fluidic chip, the device has the advantages that the device is not limited by an operation task and the size of the microsphere object,and the operational flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of micro-nano operation, and in particular relates to a device and method for moving and rotating tiny spherical objects. Background technique [0002] With the rapid development of micro-nano technology, micromanipulation technology plays an increasingly important role in the manufacture of complex mechanisms and single-cell manipulation. The rotation of tiny spherical objects is the most basic and important operation technique in micromanipulation. Both the microinjection of cells and the assembly of microstructures require multi-degree-of-freedom rotation and orientation of the target to adjust the posture to adapt to the corresponding operation. Therefore, it is crucial to find a simple, efficient, and continuous rotation method in the microscale range. [0003] The existing micro-manipulation technology for rotation is mainly the rotation operation of micro-spherical objects by micro-manipulators with ...
