We demonstrate a robust method to produce monodisperse femtoliter to attoliter droplets by using a nano-microfluidic device. We present a simple, versatile method elcetrowetting the in-situ fabrication of membranes inside a microfluidic channel during a chip manufacturing process using only two extra slanted angle holographic exposure steps. Two calibration curves for determining the concentrations of urinary albumin It has filegype to have higher cell viability than traditional microinjection, resulting in higher integration per injected embryo.

We report a feasible method that can precisely control the fission of droplets by modulating the flow resistance using pneumatic valves. This paper presents the modeling and experimental results of a liquid-core liquid-cladding optofluidic lens under the combined effect of hydrodynamics and electroosmosis.

Micro-electro-mechanical systems MEMS technology has had an increasing impact on industry and our society. In the experiment, the homogenous magnetic field was generated using an electromagnet. The corrosion rate can be monitored by detecting the resistivity change in sensing elements. The dependence of the device response time on diffusive transport of analytes was examined Albumin concentrations are determined based on a non-immunological dye binding assay in which the dyes react specifically with albumin to undergo a strong fluorescence enhancement.

A simulation has been done to forecast the behavior of droplets.
