(1) Background: Microfluidic chips have found extensive applications in multiple fields due to their excellent analytical performance. As an important platform for micro-mixing, the performance of micromixers has a significant impact on analysis accuracy and rate. However, existing with high mixing efficiency are accompanied by pressure drop, which is not conducive integration micro-reaction sy...

Microfluidic devices have become important part of technology nowadays in numerous fields application, such as chemical reactions, biosensors, synthesis nanomaterials, diagnostic device for detection biological samples, etc. In this work, a new fabrication approach, poly(dimethyl-siloxane) (PDMS) microstructures were integrated into PDMS microdevices by combining proton beam lithography and con...

We report on our investigation of a low Reynolds number non-equilibrium electrokinetic flow in a micro/nanochannel platform. Non-equilibrium electrokinetic phenomena include so-called concentration polarization in a moderate electric field and vortex formation in a high electric field. We conducted a spectral analysis of non-equilibrium electrokinetic vortices at a micro/nanochannel interface. ...

In this paper, we present a novel, simple and low-cost micromixer that is based on the manipulation of self-assembled structures by an alternating magnetic field of magnetic microbeads over the section of a microfluidic channel. The principle is demonstrated using a microfluidic chip of polymethylmetacrylate (PMMA) that contains a 200 pm wide Y-shaped microchannel and is integrated with soft fe...
