Publication number: 20230160808Abstract: A microfluidic chip configuration wherein injection occurs in an upwards vertical direction, and fluid vessels are located below the chip in order to minimize particle settling before and at the analysis portion of the chip's channels. The input and fluid flow up through the bottom of the chip, in one aspect using a manifold, which avoids orthogonal re-orientation of fluid dynamics. The contents of the vial are located below the chip and pumped upwards and vertically directly into the first channel of the chip. A long channel extends from the bottom of the chip to near the top of the chip. Then the channel takes a short horizontal turn that nearly negates any influence of cell settling due to gravity and zero flow velocity at the walls. The fluid is pumped up to a horizontal analysis portion that is the highest channel/fluidic point in the chip and thus close to the top of the chip, which results in clearer imaging.Type: ApplicationFiled: January 23, 2023Publication date: May 25, 2023Inventors: Sean Hart, Colin Hebert, Christopher Field, Shweta Krishnan
