Rapid mixing using two-phase hydraulic focusing in microchannels
Rapid mixing is important in biomedical analysis. In this study, rapid mixing is obtained through two-phase hydraulic focusing in microchannels. Two mixing streams are focused by two sheath streams. Assuming a laminar flow ...
Convective-diffusive transport in parallel lamination micromixers
Effective mixing and controllable concentration gradient are important in microfluidic applications. From the scaling law, decreasing the mixing length can shorten the mixing time and enhance the mixing quality. The small ...
Development of a polymeric micro fuel cell containing laser-micromachined flow channels
This paper presents the development of a micro fuel cell (μFC) by polymeric micromachining technique. The membrane electrode assembly (MEA) is embedded in a gold-coated polymethyl methacrylate (PMMA) substrate, on which ...
Investigation of active interface control of pressure driven two-fluid flow in microchannels
We report a novel concept to control the interface location of a pressure-driven multi-phase flow in a microchannel by using electroosmotic flow effects. This concept has potential applications in flow switching and cell ...
Nonlinear diffusive mixing in microchannels : theory and experiments
Effective mixing is an important task in microfluidics for chemical and biochemical applications. Due to the small size and consequently the low Reynolds number, mixing in microchannels relies on diffusive transport. This ...
Hydrodynamic focusing in microchannels under consideration of diffusive dispersion : theories and experiments
This paper investigates hydrodynamic focusing inside a microchannel. Hydrodynamic focusing has a number of applications in microfluidics such as micromixer, microcytometer, fluidic switch, and cell infection. In contrast ...
