摘要： In some examples, a fluid dispensing device includes a fluid chamber, a heating element adjacent the fluid chamber, and an orifice adjacent the fluid chamber. A ratio of an area of a surface of the heating element to an orifice area of the orifice is greater than or equal to 3, where the surface of the heating element faces the fluid chamber.

摘要： An example microfluidic structure can include a first microfluidic channel segment in a first elevation plane, a second microfluidic channel segment in a second elevation plane, and a transverse microfluidic channel segment connecting the first microfluidic channel segment to the second microfluidic channel segment. An angled exterior wall segment can be at the transverse microfluidic channel segment. The angled exterior wall segment can be angled in the first or second elevation plane at an acute angle with respect to a direction of fluid flow through the first or second microfluidic channel segment. A fluid cross-sectional area can increase in the fluid flow direction along the angled exterior wall segment.

摘要： A microfluidic immunoassay platform may include a substrate, a microfluidic channel in the substrate, a first set of functionalized structures along the channel, a second set of functionalized structures along the channel and an electrically driven fluid actuator contained on the substrate to move fluid containing at least one analyte along the channel through the first set of functionalized structures and through the second set of functionalized structures.

摘要： The present disclosure is drawn to microfluidic devices. A microfluidic device can include a substrate, a lid mounted to the substrate, and a microchip mounted to the substrate. The lid mounted to the substrate can form a discrete microfluidic chamber between structures including an interior surface of the lid and a portion of the substrate. The lid can include an inlet and a vent positioned relative to one another to facilitate loading of fluid to the discrete microfluidic chamber via capillary action. A portion of the microchip can be positioned within the discrete microfluidic chamber.

摘要： Examples include polymerase chain reaction (PCR) devices. Example PCR devices comprise a fluid input, ejection nozzles, and a set of microfluidic channels that fluidly connect the fluid input and the ejection nozzles. Each microfluidic channel comprises a reaction chamber, and examples further comprise at least one heating element, where the at least one heating element is positioned in the reaction chamber of each microfluidic channel. The at least one heating element is to heat fluid in the reaction chamber of each fluid channel. The device may eject fluid via the ejection nozzles.
