液滴撞击干燥倾斜壁面铺展实验研究

通过高速摄影技术及像素分析方法对液滴撞击干燥倾斜壁面进行实验研究，分析了不同倾斜角及韦伯数（We）对液滴飞溅及铺展的影响，结果表明，倾斜角的增加有利于抑制飞溅的产生；We一定时，液滴的前铺展因子随着倾斜角的增加而增加，后铺展因子随着倾斜角的增加而减小；液滴的前后初始铺展速度均大于液滴的撞击速度，且随着倾斜角的增加而减小。      

Digital Microfluidics for Manipulation and Analysis of a Single Cell

The basic structural and functional unit of a living organism is a single cell. To understand the variability and to improve the biomedical requirement of a single cell, its analysis has become a key technique in biological and biomedical research. With a physical boundary of microchannels and microstructures, single cells are efficiently captured and analyzed, whereas electric forces sort and position single cells. Various microfluidic techniques have been exploited to manipulate single cells through hydrodynamic and electric forces. Digital microfluidics (DMF), the manipulation of individual droplets holding minute reagents and cells of interest by electric forces, has received more attention recently. Because of ease of fabrication, compactness and prospective automation, DMF has become a powerful approach for biological application. We review recent developments of various microfluidic chips for analysis of a single cell and for efficient genetic screening. In addition, perspectives to develop analysis of single cells based on DMF and emerging functionality with high throughput are discussed.
