#$%^&*AU2020100689A420200625.pdf#####ABSTRACT The invention provides a photothermal microfluidic mixer based on single hole optical fiber. Its characteristics are: the photothermal microfluidic mixer consists of a section of a micromachined single hole optical fiber and an optical source. A plurality of microholes are prepared on the outside of the air hole. When different types of liquid enter the air hole through the microholes, as the optical fiber core is tangent to the air hole, after the optical energy is injected, the thermal energy radiation is generated to the microfluid, making the liquid molecules speed up the movement to achieve the purpose of mixing. The single hole optical fiber photothermal microfluidic mixer which can be used for microfluidic chips is easy to prepare, has good consistency, is easy to use with microfluidic chips, is convenient and fast to connect with an optical source, and is suitable for large-scale mass production.2/3 Microfluidic 3-1 .......... ---------. ......................... . 3--3 3-2 ------------------------------- -FIG. 3
