Patent number: 8208138Abstract: A spiral microchannel particle separator includes an inlet for receiving a solution containing particles, at least two outlets, and a microchannel arranged in a plurality of loops. Particles within a solution flowing through the spiral microchannel experience a lift force FL and a Dean drag force FD. The spiral radius of curvature R and the hydraulic diameter Dh of the spiral microchannel are such that for a flow rate U of the solution, the lift force FL and a Dean drag force FD are approximately equal and act in opposite directions for particles of a first size. The particles of the first size are focused in a single stream located at an equilibrium position near an inner wall of the microchannel. In another embodiment, a straight microchannel particle separator separates particles by modulating shear rates via high aspect ratios that focuses particles of a first size along two first walls.Type: GrantFiled: September 24, 2010Date of Patent: June 26, 2012Assignee: University of CincinnatiInventors: Ian Papautsky, Ali Asgar S.

Publication number: 20070003209Abstract: A method is provided for fabricating microelectrodes and microelectrode arrays by etching in an acid solution. Glass wafers are diced into a desired shape to form narrow probes, which are immersed in the acid solution. An organic layer on top of the acid solution forms a meniscus at the point of contact with the probes, and the taper angle on the etched probes will depend on this meniscus angle. After etching, the tapered probes are coated with a conductive layer, followed by an insulating layer over most of their length so as to leave a small conductive area exposed at the tip. The glass wafer containing the probes is then mounted on a printed circuit board carrier.Type: ApplicationFiled: October 24, 2005Publication date: January 4, 2007Inventors: Ian Papautsky, Jin Lee, Paul Bishop, Fred Beyette, Prashant Bhadri, Am Jang, William Timmons
