Abstract

 A microfluidic system for creating custom density tracer particles with low polydispersity is described in which the particle density can be fine-tuned by varying the salt concentration in the core of a double-emulsion droplet. The droplets are generated in a glass-capillary, co-flow device and then solidified lithographically for use in a variety of flow experiments, including particle-image velocimetry and multi-phase flows. The novel use of solidified, double-emulsion droplets for flow tracers provides precise control of particle density, size, shape and fluorescent properties in a form that can be easily implemented in standard, macroscale laboratory settings.

通过微流体定制密度示踪剂制造

摘要

 描述了一种用于产生具有低多分散性的定制密度示踪剂颗粒的微流体系统,其中可以通过改变双乳液液滴核心中的盐浓度来微调颗粒密度。液滴在玻璃毛细管共流装置中产生,然后进行光刻固化,用于各种流动实验,包括颗粒图像测速和多相流动。固化的双乳化液滴在流动示踪剂中的新用途,以一种可以在标准的大型实验室环境中轻松实现的形式,可以精确控制颗粒的密度,大小,形状和荧光性质。
