Dynamics of Microvalve Operations in Integrated Microfluidics

Pneumatic microvalves are widely used key components for automating liquid manipulation and flow control in microfluidics for more than one decade. Due to their robust operations and the ease of fabrication, tremendous microfluidic systems have been developed with the multiple microvalves for higher throughput and extended functionalities. Therefore, operation performance of the microvalves in ...

Micromachined Amperometric Nitrate Sensor with Integrated Microfluidics

Nitrate-sensing system that consists of a micromachined sensor substrate, nitrate-permeable membrane, integrated microfluidic channels, and standard fluidic connectors has been designed, fabricated, assembled, and tested. Our microsensor was designed for in-situ monitoring of nitrate concentrations in ground water. A silver electrode was patterned for amperometric nitrate detection. An electroc...

Graphene-Integrated Microfluidics for Advanced Crystallography

Stem cell niche engineering through droplet microfluidics.

Stem cells reside in complex niches in which their behaviour is tightly regulated by various biochemical and biophysical signals. In order to unveil some of the crucial stem cell-niche interactions and expedite the implementation of stem cells in clinical and pharmaceutical applications, in vitro methodologies are being developed to reconstruct key features of stem cell niches. Recently, drople...

Application of Microfluidics in Chemical Engineering

Microfluidics is the science and technology that involve the study of behaviors of fluids, controlled fluid manipulations, and the design of such devices or systems that can reliably perform such tasks in microchannels with typical dimensions of tens to hundreds of micrometers. For over two decades, applications of microfluidics haven been extensively explored at the interface of biology, chemi...
