In this paper, we present a technology for the batch-fabrication of fluidic devices which combines polymer and metal layers. The structures are fabricated by means of two-layer lithography and SU-8-based wafer bonding technique. The combination of SU-8 and metal layers allows the fabrication of “2(1/2)”-dimensional fluidic structures. We realized different types of micromixers for the investiga...

Fig. 1. An integrated microflow reactor system consisting of four micromixers and four microtube reactors. Driven by remarkable improvements in our understanding of factors governing organic reactions, the role of organic synthesis has been expanded to various fields of science and technology, such as new materials and new medicinal agents. Because of rapid progress in such fields, demands for ...

Three-dimensional (3D) multi-microchannel mixers can meet the requirements of different combinations according to actual needs. Rapid and simple creation of 3D multi-microchannel mixers in a “lab-on-a-chip” platform is a significant challenge in micromachining. In order to realize the complex mixing functions of microfluidic chips, we fabricated two kinds of complex structure micromixers for mu...

Electrokinetic techniques continue to play a leading role in technologies ranging from nanoparticle characterization and directed electronics assembly to micropumps and micromixers to biosensors and DNA sequencing. In this session, we invite submissions related to the development of new technologies in any of these areas, from both the fundamental and applied perspectives. Suitable topics inclu...

Four designs of ultrasonic microcages are presented together with force field simulations and experimental verification. The microcages enable three-dimensional ultrasonic manipulation of individual microparticles combined with on-line monitoring using high-resolution optical microscopy. The microcages can also be employed as acoustic-streaming-based micromixers. We investigate and compare the ...

In this work, we examine fluid mixing in a full three-stream mixing channel with longitudinal vortex generators (LVGs) built on the channel bottom by numerical simulation and experiment. The effects of the asymmetrical arrangement and the attack angle of the LVGs on fluid mixing are investigated. The results show that the micromixer with LVGs at a small asymmetry index (defined by the ratio of ...
