    Abstract: A microfluidic diagnostic chip may comprise a main fluid channel comprising a main pump, a secondary fluid channel branching off from the main fluid channel, and a secondary pump within the secondary fluid channel wherein the secondary pump is to pull a particle of analyte of a first size from a fluid passing through the main channel, the fluid comprising particles of analyte of the first size and of a number of larger sizes. A method of analyzing an analyte on a microfluidic chip may comprise pumping, with a main microfluidic pump, a fluid comprising an analyte particle through a main microfluidic channel fluidly coupled to a fluid slot and sorting the analyte particle within the fluid through a secondary microfluidic channel by pulling the analyte particle into the secondary microfluidic channel with a secondary microfluidic pump.

    Abstract: A device including a substrate and a channel formed in a layer disposed on the substrate. The layer includes a cavitation layer and a passivation layer to mitigate the effects of hydrodynamic cavitation on a surface of the channel. The passivation and cavitation material and thickness are optimized thermally to nucleate and eject a bubble at low voltages. A resistive heating element is disposed within the channel that is activated to create a micro-fluidic pump to advance a fluid through the channel. A sensor is disposed within the channel to measure a characteristic of the fluid passing through the channel.
