Design and application of microfluidic chips

Ren Chunyan;Ma Yuanyuan;Wang Jingran;Shi Jinsheng;College of Chemistry and Pharmacy,Qingdao Agricultural University;  
Ten kinds of glass microfluidic chips with different structures have been designed and fabricated.A sodium hydroxide aqueous solution and a phenolphthalein ethanol solution are introduced into the micromixer and the color changes of the two fluids in the microchannel are photographed with the help of a stereomicroscope(CCD).The width of the red liquid flow is measured,and the mixing degree of various micromixers is calculated.Finally,three kinds of micro-mixers with the continuous semi-circular structure,cylindrical structure and sector structure are selected,and the mixing degree is 100%.This experiment greatly improves the students' innovative ability and lays a good foundation for their future research work.
