Microfluidic approach for rapid interfacial tension measurement.

A novel microfluidic approach to measure interfacial tension of immiscible fluids rapidly is reported. This method rests upon quantitative force balance analysis of drop formation dynamics in a coaxial microfluidic device. The values of interfacial tension for several two liquids without/with surfactants are measured. These measurements compare well with those measured by the commercial interfa...

Measurement of ultralow interfacial tension with ADSA using an entropic edge-detector

The ultralow interfacial tension of the two-liquid phase of a ternary system 1-propanol–n-heptane–water was determined with a pendant drop method using the axisymmetric drop shape analysis (ADSA) methodology. Because the two liquid phases of the ternary system are practically miscible at temperatures near the critical solution temperature, the drops are small and difficult to distinguish from t...

Analysis of an Optofluidic Biochemical Sensor

We introduce a novel optofuidic biochemical sensor in which detection is based on the contrast between the refractive index of a target biomaterial and ambient carrier fluid. The sensor consists of parallel vertical micochannels embedded in a planar substrate. The central microchannel is illuminated by a focused beam of light and the periodic spacing of the channels combined with the contrast i...

Measurement of small molecule diffusion with an optofluidic silicon chip.

In this work we explore the micro-ring resonator platform to study the diffusion-driven mass transport of small molecules within microfluidic channels. The micro-ring resonators are integrated on a silicon-on-insulator photonic chip and combined with microfluidics in poly(dimethylsiloxane) (PDMS). We apply a strong initial gradient in the solute concentration and use the micro-ring resonators t...

Microfluidic sensor for dynamic surface tension measurement.

A novel microfluidic sensor for measuring dynamic gas-liquid interfacial tension is reported. The device consists of a microfluidic chip with a microchannel network and an optical detection system. The sample is introduced into a main channel, while air is injected through a T-junction. Owing to the fixed flow rate ratio used for the sensor, surface tension is the only parameter determining bub...
