A High Aspect Ratio Bifurcated 128-Microchannel Microfluidic Device for Environmental Monitoring of Explosives

The Application of Surface Mount Processes for the Economical Production of High-aspect-ratio Microchannel Arrays

This paper reports on the feasibility of using surface mount technology (SMT) assembly processes and materials to produce highly parallel, high-aspect ratio microchannel arrays. Experimental results show that the fabrication of high-aspect-ratio (> 40:1) microchannel arrays is possible using solder paste, screen printing, and reflow bonding. A simple model and empirical examination verifies tha...

Effects of rectangular microchannel aspect ratio on laminar friction constant

In this paper, the effects of rectangular microchannel aspect ratio on laminar friction constant are described. The behavior of fluids was studied using surface micromachined rectangular metallic pipette arrays. Each array consisted of 5 or 7 pipettes with widths varying from 150 μm to 600 μm and heights ranging from 22.71 μm to 26.35 μm. A downstream port for static pressure measurement was us...

Fabrication of Vertical and High-aspect-ratio Glass Microfluidic Device by Borosilicate Glass Molding to Silicon Structure

We propose a fabrication method of vertical and high-aspect-ratio microfluidic device which is made of borosilicate glass. Glass microfluidic devices have high demand because of its chemical stability, good bio compatibility, and high optical transparency. We realized vertical glass microwells of 25 μm in diameter and 50 μm in depth(aspect ratio: 2), and micropillars of 3 μm in diameter and 25 ...

High-aspect ratio through-silicon vias for the integration of microfluidic cooling with 3D microsystems

Modulation of rotation-induced lift force for cell filtration in a low aspect ratio microchannel.

Cell filtration is a critical step in sample preparation in many bioapplications. Herein, we report on a simple, filter-free, microfluidic platform based on hydrodynamic inertial migration. Our approach builds on the concept of two-stage inertial migration which permits precise prediction of microparticle position within the microchannel. Our design manipulates equilibrium positions of larger m...
