在这项研究中，我们提出了一种使用振动气泡的微粒精细聚焦的方法。2.01 μ m和6.60 μm的荧光聚苯乙烯颗粒被显示为沿着50 μ m宽的通道的边缘聚焦。该机制被确定为剪切应力引起的振动的气体/液体弯月面上的边界层。实验结果表明，聚焦区宽度随激励幅值的增大而减小，聚焦对流量的敏感性不如激励频率，且存在一个最佳气泡半径。最后，我们证明了红细胞和6.60 μm的颗粒可以聚焦成有效的单线。
In this study, we present a method for fine focusing of microparticles using a vibrating air bubble. Fluorescent polystyrene particles of 2.01 and 6.60 μm are shown to be focused along the edge of a 50-μm-wide channel. The mechanism is determined to be shear stresses caused by the boundary layer on the vibrating gas/liquid meniscus. Experiments show that the focussing region width reduces with higher excitation amplitude, focusing is not as sensitive towards the flow rate as the excitation frequency, and there is an optimal bubble radius. Finally, we show that red blood cells and 6.60 μm particles can be focused into what is effectively a single line.
