Abstract: A microfluidic diagnostic chip may comprise a substrate, a plurality of fluidic slots extending through the substrate, a plurality of microfluidic channels each coupled to a respective one of the plurality of fluidic slots to receive a plurality of fluids from the plurality of fluidic slots, and a mixing region in fluid communication with the plurality of fluidic slots to receive the plurality of fluids such that the plurality of fluids are to mix. A diagnostic chip may comprise a number of fluid slots defined through a substrate and a plurality of microfluidic channels coupled to the fluid slots to receive from the fluid slots a plurality of different fluids wherein the microfluidic channels combine and mix the plurality of different fluids.

Abstract: A printhead includes a plurality of firing chambers, a plurality of fluid ejectors, and at least one field generating member. Each one of the firing chambers includes a nozzle region to receive printing fluid. The printing fluid includes an ink vehicle having pigments disposed therein. At least one field generating member generates a non-uniform electric field to apply forces to maintain respective pigments in the ink vehicle of the printing fluid in the nozzle region.
