ナノ秒レーザー誘起爆発で導くマイクロポンプの駆動

抄録

Recently micro-fluidic devices have attracted much attention especially for applications in the biotechnology and chemical engineering. The advantage of microfluidic devices is that fewer biological materials and chemicals are needed for experiments. To achieve high functions in these devices, it is indispensable to equip robust and compact micropump elements. In this work, we produced the propeller used for micro-pump driven by nanosecond laser-induced bubbling. When intense laser pulses are focused on a liquid in the microfluidic device, a jet flow is induced with shockwave and stress generation, which is a source of the bubbling. The focused laser pulse was utilized as an ignitor to rotate propeller in the device i.e., this micro-pump is not required to equip ignitor in the device.
