Abstract
A microfluidic cartridge may have a microfluidic channel that is configured to reduce or eliminate bubble formation in liquids disposed within or flowing through the microfluidic channel. In some cases, the microfluidic channel may be considered as having a channel surface, and a polymeric coating or film may be disposed on the channel surface to help reduce or eliminate bubble formation in liquids disposed within or flowing through the channel. In some cases, the polymer coating or film may be formed from a block copolymer having a hydrophobic portion that bonds to the channel surface and a hydrophilic portion that reduces surface tension of the channel surface.
