Problems solved by technology

However, this method can only make the trapped particles rotate around the optical axis, and the two poles of the rotation axis cannot be observed through the microscope.
In addition, the method of rotating cells by rotating a ceramic ferrule requires extremely high mechanical precision and is very difficult

Embodiment 1

[0049] Example 1: Rotation control of human red blood cells based on an angle-deviation seven-core optical fiber cell optical motor system:

[0050] figure 1 It is a differential torque optical motor system based on dual seven-core terminals. In the system, the laser is led from the laser 1 to the fiber beam splitter 2 through a fiber jumper, so that one beam of laser light is divided into 14 beams of laser light. The 14 light beams are respectively connected to the attenuators 3-1 to 3-14. The seven optical paths drawn from the attenuators 3-1~3-7 are connected to the seven-core optical fiber combiner 4-1, and the other seven optical paths drawn from the attenuators 3-8~3-14 are connected to the multi-core optical fiber combiner 4-2. The multi-core fiber arms 5-1 and 5-2 for capturing and rotating cells are respectively connected to the seven-core fiber combiners 4-1 and 4-2.

[0051] The number of each core of the seven-core optical fiber is as follows: Figure 5 shown. ...

Abstract

The invention provides an angular deviation type double-multi-core optical fiber cell optical motor system with cell capturing and rotating functions. The optical motor system includes a laser 1 generating a desired light source, an optical fiber beam splitter 2, an attenuator 3, multi-core optical fiber beam combiners 4-1 and 4-2, multi-core optical fiber arms 5-1 and 5-2, an experiment operationpool 6, and a microscopic imaging system 7 for observing the experiment operation process; and the multi-core optical fiber arms 5-1 and 5-2 are respectively connected with the two multi-core opticalfiber beam combiners and are used for capturing and rotating cells. The angular deviation type double-multi-core optical fiber cell optical motor system can be used for capturing single cells or multiple cells, rotating the single cells or multiple cells in the opposite direction, capturing and arranging micro-particles, and providing power for a micro-robot or a micron-sized instrument. The angular deviation type double-multi-core optical fiber cell optical motor system can be widely applied to the fields of cell analysis, drug development and microscopic manufacturing.

Description

[0001] (1) Technical field [0002] The invention relates to an angle-deviation double-multicore optical fiber cell optical motor system. The invention can be used for the capture of single cells or multi-cells and their multi-directional rotation operations, as well as the capture and arrangement of tiny particles. It can also be a micro Powered by robots or micron-scale instruments. It can be widely used in the fields of cell analysis, drug development, and micromanufacturing. [0003] (2) Background technology [0004] Angle-deviation dual multi-core fiber optic cell optical motor system is a development and application of fiber optic tweezers. [0005] In the field of optical tweezers, the Ashkin experimental group at Bell Laboratories has done pioneering work. In 1970, Ashkin estimated that a focused laser could propel micron-sized particles. He placed latex microspheres with a diameter of 0.6-2.5um in water, and focused two argon ion lasers with a power of 1w in the wa...
