Abstract: A microfluidic diagnostic chip may comprise a microfluidic channel, a functionalizable enzymatic sensor in the microfluidic channel, the functionalizable enzymatic sensor comprising a binding surface to bind with a biomarker in a fluid, and a microfluidic pump to pass the fluid over the binding surface. A microfluidic device may comprise a number of pumps to pump a fluid though the number of microfluidic channels and a number of microfluidic channels comprising at least one sensor to detect a change in a chemical characteristic of the fluid in response to presence of the fluid on the sensor

Abstract: A system may comprise a voltage upconverter, a universal serial bus (USB) connector to receive an input voltage from a USB port on a computing device, and a microfluidic diagnostic chip communication link to electrically couple the voltage upconverter to a microfluidic diagnostic chip wherein the voltage upconverter is to convert the input voltage to be received by the USB connector to an output voltage sufficient to drive a pump on the microfluidic diagnostic chip. A diagnostic system may comprise a microfluidic diagnostic chip comprising a pump and a voltage upconverter to receive an input voltage from a universal serial bus (USB) port of a computing device and to convert the input voltage into an output voltage that powers activation of the pump.

Abstract: A fluid testing system comprises controlling hardware that serves to control an electric sensor on a fluid testing cassette. In one implementation, the controlling hardware is part of a cassette interface. In another implementation, the controlling hardware is part of the portable electronic device. In one implementation, the fluid testing system applies two different frequencies of alternating current are applied to two different electric sensors.

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.
