Abstract: A microfluidic device may, in an example, include at least one microfluidic channel, a dielectrophoresis separator to separate a plurality of cells passing within the at least one microfluidic channel, and a thermal resistor to eject at least one cell from the microfluidic device. A cassette may, in an example, include a die coupled to a substrate of the cassette, the die including at least one microfluidic channel, a dielectrophoresis separator along the microfluidic channel to separate a plurality of cells passing within the microfluidic channel, and an ejection device to eject at least one of the plurality of cells into an assay well.

Abstract: Optical readers are disclosed in examples herein. An example optical reader including a light source to emit a light beam; and a spot pattern generator to receive the light beam and to generate a two-dimensional spot array from the light beam, the two-dimensional spot array to be directed toward a substrate having nanostructures, the two-dimensional spot array to be sensed to detect a presence or an absence of a substance of interest on the substrate.

Abstract: According to an example, a microfluidic apparatus may include a fluid slot, a foyer in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer, a sensor to detect a presence of a particle of interest in a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to receive information from the sensor, determine, from the received information, whether a particle of interest has passed through the channel, and control the actuator to expel fluid in the foyer through the nozzle based upon the determination.
