    Abstract: The present disclosure is drawn to microfluidic chips. The microfluidic chips can include an inflexible material having an elastic modulus of 0.1 gigapascals (GPa) to 450 GPa. A microfluidic channel can be formed within the inflexible material and can connect an inlet and an outlet. A working electrode can be associated with the microfluidic channel and can have a surface area of 1 μm2 to 60,000 μm2 within the microfluidic channel. A bubble support structure can also be formed within the microfluidic channel such that the working electrode is positioned to electrolytically generate a bubble that becomes associated with the bubble support structure.

    Abstract: In one example in accordance with the present disclosure, a fluid analysis device is described. The device includes a substrate, a die adhered to the substrate, and at least one fluid analysis element disposed on the die. A lid is adhered to the substrate and includes a channel formed thereinto be seated over the die. The device also includes an inlet port to the channel and an outlet from the channel. The inlet port and the outlet port are formed on at least one of the substrate and the lid. A number of electrical traces couple the die to a controller.

    Abstract: In one example in accordance with the present disclosure, a fluid analysis device is described. The fluid analysis device includes a chamber to receive a number of fluids. At least one fluid includes an electrochemical label with a unique electrochemical response to an applied electrical potential. A multi-electrode sensor of the fluid analysis device is disposed within the chamber and detects electrical signals within the chamber. The fluid analysis device also includes a controller coupled to the multi-electrode sensor. The controller applies an electrical potential across multiple electrodes of the multi-electrode sensor and identifies, from the electrical signal detected by the multi-electrode sensor, fluids currently in the chamber based on the unique electrochemical responses of associated electrochemical labels.

    Abstract: According to an example, a microfluidic apparatus may include a fluid slot and a foyer that is in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer. The microfluidic apparatus may also include an electrical sensor to measure a change in an electrical field caused by a particle of interest in a fluid passing through the channel from the fluid slot to the foyer, an actuator to apply pressure onto fluid contained in the foyer, and a controller to receive the measured change in the electrical field from the electrical sensor, determine, from the received change in the electrical field, an electrical signature of the particle of interest, and control the actuator to control movement of the particle of interest based upon the determined electrical signature of the particle of interest.

    Abstract: An example device includes a processor to connect to an electrode disposed within a microfluidic volume and to connect a second electrode that includes a surface of silver metal disposed within the microfluidic volume. The processor is to apply an electrical potential between the electrode and the second electrode when the microfluidic volume contains a fluid that contains chloride ions to form a layer of silver chloride on the surface of the second electrode. The processor is further to cease application of the electrical potential and operate the second electrode as a reference electrode in a measurement process performed within the microfluidic volume.
