Problems solved by technology

[0008] Many universities around the world have done a lot of research on the design of the rotor shape based on the principle of "windmill-like rotation", and have made great progress and good research results. However, there are still problems such as the rotor cannot rotate stably, and the optical drive device and other restrictions make the scope of application limited

Embodiment Construction

[0031] The present invention will be described in more detail below in conjunction with the accompanying drawings by taking a three-core optical fiber as an example:

[0032] combine figure 1 , 3, it is mainly composed of the optical tweezers 4 formed by the finely processed multi-core optical fiber 1 at the front end, which automatically captures the sphere of the micro-rotor 5 in the solution to form an optical power drill system; Figure 7-9 , the micro-rotor structure includes a top sphere, a rotating shaft, a "windmill-like" rotor structure that connects multiple wings with slopes and semi-cylinders, and the bottom end is a cone tip; after the front end of the multi-core optical fiber captures the sphere, it plays a role While the axis is fixed, the outgoing light is irradiated vertically to the wing with the slope to realize the rotation, and at the same time, it drives the bottom cone to rotate to play the role of a photodynamic drill. The multi-core optical fiber whos...

Abstract

The invention provides an automatic assembly type photodynamic drill based on multi-core fiber. The automatic assembly type photodynamic drill comprises front optical tweezers and a micro rotor formed by processed multi-core fiber. In solution the optical tweezers automatically captures the micro rotor to form a photodynamic drill. The micro rotor structure comprises a ball, a rotating shaft, a windmill like rotor structure composed of a plurality of wings and a cone tip, wherein the ball is at the top of the rotating shaft, the windmill like rotor structure composed of a plurality of wings is at the middle of the rotating shaft, and the cone tip is at the bottom of the rotating shaft. According to the invention, the micro rotor ball can automatically form a photodynamic drill once captured. The photodynamic drill has the advantages of convenient operation, simple structure, and easy control. The dimension of the photodynamic drill is micron-sized, and the rotating speed is easy to control from outside. The photodynamic drill can be applied to microbe punching such as cell wall punching. Accordingly, the automatic assembly type photodynamic drill based on multi-core fiber providesa strong tool for micro life science and biomedical researches.

Description

technical field [0001] The invention relates to an optical power drill, in particular to a self-assembled optical power drill based on multi-core optical fibers. Background technique [0002] Photoinduced rotation is an effective means to realize micro-mechanical motors. With the development of science and technology, as well as the development of processing technology and computer technology, the application prospect of photoinduced rotation will become more and more extensive. The method of photoinduced rotation can not only be applied to micro total analysis It acts as an agitator in the system, and can also be applied to micropumps, and can also be used to study rotating motor proteins, microscopic properties of fluids, cell membrane shear force, microdrilling, etc. Medicine provides a powerful tool. [0003] In 1936, R.A.Beth experimentally let a beam of circularly polarized light pass through a half-wave plate suspended by a filament, and for the first time used the a...
