In this paper, a passive planar micromixer with ellipse-like micropillars is proposed to operate in the laminar flow regime for high mixing efficiency. With a splitting and recombination (SAR) concept, the diffusion distance of the fluids in a micromixer with ellipse-like micropillars was decreased. Thus, space usage for micromixer of an automatic sample(More)
In the present work, the microfabricated impedance sensing array (MISA) unit, based on interdigitated microelectrodes (IDMEs) coated with nickel hexacyanoferrate (NiHCF) film, is presented as an alternative solution to detect pathogens. The NiHCF film, which provide a [Fe(CN)<inf>6</inf>]<sup>3-/4-</sup> probe-free redox reaction, was functionalized with(More)
Clogging failure is common for microfilter utilizing the flat membrane structure. To reduce clogging failure in microfilters, the turbine blade-like micropillar is introduced in microfilter design. Two improved cross-flow microfilter designs employing the blade-like micropillar barrier are presented, one with varied cross-section channels, and the other(More)
