    Abstract: The present disclosure is drawn to microfluidic devices. In one example, a microfluidic device can include a driver chip and a fluid chamber located over the driver chip. First and second microfluidic loops can have fluid driving ends and fluid outlet ends connected to the fluid chamber. The first and second microfluidic loops can include a portion thereof located outside a boundary of the driver chip. A first fluid actuator can be on the driver chip associated with the fluid driving end of the first microfluidic loop to circulate fluid through the first microfluidic loop. A second fluid actuator can be on the driver chip associated with the fluid driving end of the second microfluidic loop to circulate fluid through the second microfluidic loop.

    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: The present disclosure is drawn to temperature-cycling microfluidic devices. In one example, a temperature-cycling microfluidic device can include a driver chip having a top surface and a heat exchange substrate having a top surface coplanar with the top surface of the driver chip. A fluid chamber can be located on the top surface of the driver chip. A first and second microfluidic loop can have fluid driving ends and fluid outlet ends connected to the fluid chamber and can include portions thereof located on the top surface of the heat exchange substrate. A first and second fluid actuator can be on the driver chip. The first and second fluid actuators can be associated with the fluid driving ends of the first and second microfluidic loops, respectively, to circulate fluid through the first and second microfluidic loops.
