We currently use Adobe Illustrator to design silicone gasket geometries for our microfluidic devices. Here is a quick way to do a similar thing from sketchup. The advantage of this procedure is that you can create a complete 3d model of your device and export different snapshots to the 3d printer for bulk fabrication and a…
Summary and Instructional video The simplest way to get something wet is to allow water to condense on the surface of the something. In our case, we have a number of nanocavities (~ 0.1 femtoliters) with porous tents over them. The easiest thing to do is simply chill the substrates down to allow condensation to form….
Background Previously, we have demonstrated multiplexed digital sensing on MCP1, KC and TNFα secreted by RAW 264.7 cells stimulated in conventional cell culturing well plates. We observed decent TNFα and strong MCP1 response but no KC secretion from RAW cells upon 100ng/ml of LPS stimulation overnight. The work verified our platform’s capability of multiplex cytokine…

Introduction When searching for a flow control system for microfluidic cell culture, we look to balance the ease of use, accessibility, and precision of fluidic control. For instance, researchers have explored different powered actuation methods for miniaturized precise proportional fluid control. These actuation methods include electromechanical, electrostatic, electromagnetic, piezoelectric, and thermal-based. The necessary power sources,…
Introduction My previous post focused on attempts to reproducibly generate collagen IV with human umbilical vein endothelial cells (HUVECs) so that we would be able to establish protocols for basement membrane protein detection and degradation measurement. Following my presentation on November 18 2020, there were some questions regarding whether or not the observed collagen IV…
