生成单个小液滴为需要精确体积和浓度控制的各种应用提供了独特的可能性。本文提出了一种基于可控弯月面破碎过程的超小液滴生成方法。该方法利用通过三通接头连接到计算机控制的注射器的两个喷嘴。使用注射器从两个孔挤出液体,直到它们通过液体弯月面连接。接下来,将液体排出弯液面并返回喷嘴将导致弯液面变薄,这将最终导致其破裂并形成一个小液滴。实验和理论研究证明了所提出的方法的有效性。结果表明,可以产生体积从毫微微升到纳升的液滴。
Generating individual, small droplets offers unique possibilities for various applications where precise volume and concentration control are necessary. This paper presents a systematic method for generating ultra-small droplets based on a controllable meniscus break-up procedure. The method utilizes two nozzles that are connected to a computer-controlled syringe through a three-way junction. A syringe is used to extrude the liquid from both orifices until they are connected by a liquid meniscus. Next, draining the liquid out of the meniscus and back into the nozzle will cause the meniscus to thin, which will ultimately result in its break-up and the formation of one small droplet. Both experimental and theoretical studies are presented to demonstrate the validity of the proposed method. It is shown that droplets with volumes from femtoliters to nanoliters can be generated.
