Abstract: One example provides a fluidic die including a nozzle layer disposed on a substrate, the nozzle layer having an upper surface opposite the substrate and including a plurality of nozzles formed therein, each nozzle including a fluid chamber and a nozzle orifice extending through the nozzle layer from the upper surface to the fluid chamber. A conductive trace is exposed to the upper surface of the nozzle layer and extends proximate to a portion of the nozzle orifices, an impedance of the conductive trace indicative of a surface condition of the upper surface of the nozzle layer.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a channel, an energy source, and a transfection chamber. The channel includes an indentation to hold a cell. The energy source is to apply a shockwave to the cell in the channel to porate the cell. The transfection chamber is to store a reagent to be inserted into the cell after the cell is porated.

Abstract: A reagent module may include a first reagent dispensing device to dispense a first range of volumes of a first reagent, and a second reagent dispensing device to dispense a second range of volumes of a second reagent where the second range of volumes is more voluminous relative to the first range of volumes. The reagent dispensing system may further include a third reagent dispensing device to dispense a third range of volumes of a third reagent where the third range of volumes is more voluminous relative to the second range of volumes.

Abstract: A cleansing device can trigger a user action to commit the cleansing device to one of a subscription plan or trade use plan. The cleansing device can consume the cleansing material in in accordance with the subscription plan or the trade use plan based on the user action. The controller can commit the cleansing device to one of the subscription plan or trade use plan by persistently implementing a corresponding configuration for the committed subscription plan or trade use plan respectively. When the configuration is implemented for at least the subscription plan, the controller controls the container dispenser in using the cleansing material to be in accordance with a set of rules of the subscription plan, without an ability of a user to manually bypass or override control of the container dispenser in using the cleansing material.

Abstract: Provided in one example is an apparatus, including a substrate supporting a microfluidic channel, a bubble jet inertial pump supported by the substrate adjacent the microfluidic channel to pump fluid through the microfluidic channel and an optical sensor on a first side of the microfluidic channel. A light emitter on a second side of the microfluidic channel is to pass light across the microfluidic channel to the optical sensor.

Abstract: In one example in accordance with the present disclosure, a particle dispensing system is described. The particle dispensing system includes a port to receive a number of fluid cartridges. Each fluid cartridge is to hold an amount of fluid to be ejected. The particle dispensing system also includes an optical verification system to determine, following ejection, a count of a number of particles ejected during an ejection event. The particle dispensing system also includes a controller to selectively activate a number of fluid ejectors to eject the amount of fluid.

Abstract: An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.
