|Title:||Microfluidic interfacial tensiometry|
|Published:||August 17, 2005|
|Abstract:||A microfluidic approach to measure interfacial tension of immiscible fluids rapidly is reported. This method rests upon quantitative real-time analysis of two-phase flow and drop-shape dynamics. Drops of prescribed dimension and spacing are produced, accelerated, and deformed under extensional flow. These measurements compare well with existing published data and demonstrate a wide range of accessible interfacial tension e.g., from (2.5 to 60) mN/m.|
