Abstract

The invention provides a photothermal microfluidic mixer based on a single-hole optical fiber. It is characterized in that the photothermal microfluidic mixer is composed of a section of micro-processed single-hole optical fiber and a light source. Multiple microholes are prepared on the outside of the air hole. When different liquids enter the air hole through the microhole, since the optical fiber core is tangent to the position of the air hole, heat energy radiation is generated on the microfluidic liquid after passing through the light energy, making the liquid molecules Accelerate the movement to achieve the purpose of mixing. The single-hole fiber optic photothermal microfluidic mixer that can be used in microfluidic chips is simple to prepare, has good consistency, is convenient to use with microfluidic chips, is convenient and quick to connect with a light source, and is suitable for large-scale mass production.

Description

(1) Technical field [0001] The invention relates to a photothermal microfluidic mixer based on a single-hole optical fiber, which is convenient to be used with a microfluidic chip, and can also replace a microfluidic channel structure unit with a mixing function in the chip in the operation of a micro-scale liquid in a micrometer scale. technical field. (2) Background technology [0002] Microfluidics (Microfluidics or Lab-on-a-chip) refers to systems that process or manipulate tiny fluids using microchannels of tens or hundreds of microns. After decades of development, microfluidic technology has become an emerging interdisciplinary subject involving chemistry, fluid physics, optics, microelectronics, new materials, biology and biomedical engineering. Due to the small size of the sample in the microfluidic chip, the short detection optical path, the optical detector with high sensitivity, fast response time, and low power consumption, and new detection methods are very imp...
