    摘要： The invention relates to and provides a microfluidic mixer, formed by two parts, a first part being a substrate 30 having formations defining fluid channels on an outer surface that is directed towards a second part, which is a flexible layer 20, wherein the flexile layer has formations defining fluid channel which, when the flexible layer is positioned over the substrate so as to cover the fluid channels of the substrate to provide a fluid communication path, wherein a section of said communication path comprises at least a first and a second fluid channel 1, 2 for providing a first and a second fluid, wherein first and second fluid channel merge before an inlet 9 of a mixing chamber 10 into a merged fluid channel 5, wherein the mixing chamber comprises perturbation formations 12, and an outlet 11 of the mixing chamber is connected to an outlet fluid channel 13, wherein the flexible layer comprises points for compression at the inlet and outlet of the mixing chamber for closing the merged fluid channel and the outlet fluid channel connected to inlet and outlet of the mixing chamber, characterised in that the perturbation formations of the mixing chamber are vertically arranged walls, pillars, or tubes with respect to an inner surface.

    摘要： A method for printing one or more desired features on a polymeric substrate. In an example embodiment, the method includes receiving an ink that includes a bio-reactive indicator material, and employing a piezoelectric printhead to deposit the ink on a polymeric substrate. The polymer substrate with the ink deposited thereon represents a diagnostic testing device for performing a test on a material sample. The method further includes employing UltraViolet (UV) light to cure the ink. The ink may include an electrically conductive material. A UV light source may be coupled to a piezoelectric printhead and actuated in response to a control signal from a controller to facilitate curing materials deposited on the polymeric substrate.

    IPC分类号： B01L3/00

    摘要： The invention relates to a method and a system for providing fluids, comprising two components, wherein a first component is a container with at least one first reservoir for taking up a fluid and a second reservoir for ventilation of the system, wherein said first and second reservoir are sealed with a seal, and a second component which is a dock for taking up the container, wherein the dock comprises an inner bottom surface comprising first formations for fluid piercing of the container's at least one first reservoir for taking up a fluid and second formations for piercing of the container's second reservoir for ventilation, and wherein said inner bottom surface is a drain plate comprising a drain, wherein the container has fins on its outer edge which engage into two parallel arranged recesses at the inner side surface of the dock for fixing the container within the dock in a first position when the fins of the container engage in a first recess which is a storage snap fit or a second position when the fins of the container engage in second recess at the inner side surface which is a retain snap fit

    摘要： The invention relates to structures for supporting the filling of wells, in particular in microfluidic devices and provides a microfluidic device, comprising a substrate with at least a first horizontal channel which continues as a first vertical chimney channel into a first well having a greater depth than the first horizontal channel with respect to an upper surface of the substrate, wherein the first vertical channel is half open to the volume of the first well. A method for filling a well of a microfluidic device using the device is also an object of the disclosure.
