流体流动的控制对微流体装置的操作至关重要。传统的微流体泵往往是昂贵的,笨重的,复杂的,并不能在有限的资源设置。在这里,我们介绍了一个完全自给自足,稳健,重力辅助,低成本(节俭)的微流体泵。该泵由注射器、注射器支架和装载质量组成。该系统易于组装,价格低廉,便携,且无需电力。在注射器内,液体由装载质量的重量所产生的压力驱动。因此,在运行过程中,施加的压力是动态可控的,并且在数小时内保持稳定,这对微流体分析和动态时间研究的优化是有用的。我们演示了该系统在控制油包水液滴乳化液形成中的应用。得益于其简单性和多功能性,节约型微流控泵将使微流控技术在化学和生物医学应用中的全球采用,特别是在资源有限的环境中。一个节俭的微流体泵是一个流体驱动系统,是完全自给自足,稳健,重力辅助,低成本(节俭)。该泵可为多功能微流体应用产生压力。
Manipulation of fluid flow is paramount for microfluidic device operation. Conventional microfluidic pumps are often expensive, bulky, complicated, and not amenable in limited resource settings. Here, we introduce a Fully self-sufficient, RobUst, Gravity-Assisted, Low-cost (FRUGAL) microfluidic pump. The pump consists of a syringe, a syringe holder and loading masses. The system is easy to assemble, inexpensive, portable, and electrical power-free. Inside the syringe, the fluid is driven by the pressure from the weight of the loading masses. Therefore, during operation, the exerted pressure is dynamically controllable and stable for hours, features that are useful for optimization of microfluidics assays and dynamic temporal studies. We demonstrate the application of this system to control the formation of water-in-oil droplet emulsion. Benefitting from its simplicity and versatility, the frugal microfluidic pump will enable global adoption of microfluidic technology in chemistry and biomedical applications, especially in limited resource environments. A frugal microfluidic pump is a fluid actuation system that is Fully self-sufficient, RobUst, Gravity-Assisted, Low-cost (FRUGAL). The pump can generate pressure for versatile microfluidic applications.
