Rapid measurement of hydrogen sulphide in human blood plasma using a microfluidic method.

Hydrogen sulfide (HS) is emerging as an important gasotransmitter in both physiological and pathological states. Rapid measurement of HS remains a challenge. We report a microfluidic method for rapid measurement of sulphide in blood plasma using Dansyl-Azide, a fluorescence (FL) based probe.

A microfluidic device with focusing and spacing control for resistance-based sorting of droplets and cells.

This paper reports a novel hydrodynamic technique for sorting of droplets and cells based on size and deformability. The device comprises two modules: a focusing and spacing control module and a sorting module. The focusing and spacing control module enables focusing of objects present in a sample onto one of the side walls of a channel with controlled spacing between them using a sheath fluid.

Hydrodynamic resistance and mobility of deformable objects in microfluidic channels.

This work reports experimental and theoretical studies of hydrodynamic behaviour of deformable objects such as droplets and cells in a microchannel. Effects of mechanical properties including size and viscosity of these objects on their deformability, mobility, and induced hydrodynamic resistance are investigated. The experimental results revealed that the deformability of droplets, which is quantified in terms of deformability index (D.
