Embodiment Construction

[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0025] to combine figure 1 , 2, 3, the present invention is based on the micro-stirrer driven by multi-core optical fiber and comprises the multi-core optical fiber of the taper shape 6 that a section of multi-core optical fiber 4 is made through fusion tapering and the tiny particle 8 that is made of composite material, and multi-core optical fiber has 3-4 fiber cores 5. The tiny particles are located at the cone end of the cone-shaped multi-core fiber. The non-taper end of the cone-shaped multi-core fiber is connected to the light source through the light source tail fiber. The multiple cores of the cone-shaped multi-core fiber act on the vertical suspension at the same time tiny particles in the liquid. Simultaneously combine Figure 6-1 to Figure 6-3 , the upper body of the tiny particle is a sphere and a rotating shaft made of a material with a lower dens...

Abstract

The invention provides a micro stirrer driven by a multi-core fiber, comprising a pyramidal multi-core fiber made of a section of multi-core fibers via fused biconical taper and small particles made from composite materials, wherein the small particles are located at the pyramidal end of the pyramidal multi-core fiber; the non-pyramidal end of the pyramidal multi-core fiber is connected with a light source; a plurality of fiber core emergent lights of the pyramidal multi-core fiber simultaneously act on the small particles in a vertical suspension liquid; the upper body of each small particle is a sphere and a rotating shaft which are made from materials with lower density; and the bottom of the each small particle is of a windmill-shaped structure with a plurality of wings made from materials with higher density. The micro stirrer provided by the invention has the characteristics of small volume, light weight, simple structure, low price, easiness in operation, high mixing efficiency, benefit of the reduction of reagents, and the like and can be widely applied to the fields of biology and chemistry.

Description

technical field [0001] The invention relates to a micro-stirrer, in particular to a micro-stirrer composed of multi-core optical fibers to drive tiny particles. Background technique [0002] In recent years, Micro Total Analysis System (μTAS), also known as a laboratory built on a single chip, has set off a huge wave of research in the fields of medical research, biological application analysis and chemistry. Among them, the micro-stirrer is one of the most important parts for the fastest and most complete mixing of various micro-fluidic samples. Therefore, it is becoming more and more important to design and manufacture micro-stirrers. In general, micro-stirrers can be divided into two categories: passive and active, also known as stationary and rotating. Relying on molecular diffusion and chaotic convection, the passive micro-stirrer has a simple structure, does not require external energy to drive stirring, and is stable. This is also the first reported type of microst...
