Abstract: The present disclosure is drawn to microfluidic devices. In one example, a microfluidic device can include a first covered fluid feed slot in fluid communication with a first microfluidic channel and a second covered fluid feed slot in fluid communication with a second microfluidic channel. The first microfluidic channel can be formed adjacent to the second microfluidic channel but not in fluid communication with the second microfluidic channel. The first covered fluid feed slot can include a first fluid feed hole for filling a fluid into the first covered fluid feed slot. The second covered fluid feed slot can also include a second fluid feed hole for filling a fluid into the second covered fluid feed slot.

Abstract: Examples include microfluidic devices. Example microfluidic devices comprise a first microfluidic channel, a second microfluidic channel, and microfluidic output channel fluidly coupled to the first microfluidic channel and the second microfluidic channel via a fluid junction. The example device comprises a first fluid actuator disposed in the first microfluidic channel to actuate to thereby pump a first fluid into the microfluidic output channel, and the example device comprises a second fluid actuator disposed in the second microfluidic channel to actuate to pump a second fluid into the microfluidic output channel. The first fluid actuator and the second fluid actuator are to actuate to thereby pump a fluid mixture of the first fluid and the second fluid into the microfluidic output channel.

Abstract: A microfluidic filtering system may include a first microfluidic channel, a first pump to move fluid along the first microfluidic channel in a first direction, a second microfluidic channel, a second pump to move fluid along the second microfluidic channel in a second direction opposite to the first direction and a filter channel extending between and interconnecting the first microfluidic channel and the second microfluidic channel.
