    摘要： A fluidic device for performing assays can include control components such as vacuum pumps, gas pumps, “broken open valves,” and “self-close valves” for controlling the flow of fluids in the fluidic device. The vacuum pump can be used to pull a fluid in a specific direction in a channel, and the gas pump can be used to push a fluid in a specific direction in a channel. The broken open valve can be used to connect two separate regions at the control of a user, and the self-close valve can be used to automatically seal off a channel after passage of a fluid. The vacuum pumps, gas pumps, broken open valves, and self close valves can be made small in volume so that the fluidic device can be made as a small and portable device.

    摘要： A fluidic device includes a first reservoir to receive a first fluid, a second reservoir to receive a second fluid, and a main channel coupled to the first and second reservoirs through one or more branch channels. A first one-use pump generates a pressure difference to move one or both of the first and second fluids when a container in the first one-use pump is broken. A second one-use pump generates a pressure difference to move one or both of the first and second fluids when a container in the second one-use pump is broken.

    摘要： A method for manufacturing a micro nozzle is disclosed. The method includes the following steps: providing a substrate having a channel for fluids, wherein the thickness of the substrate is D1 and the depth of the bottom of the channel is D3; forming a protrusion having an acute angle θ on the edge of the substrate through the cutting operation; and further forming a nozzle with a thickness D2 of on the tip of the protrusion. The outlet of the channel is located on the tip of the protrusion. Moreover, the thickness of the nozzle on the tip of the protrusion is less than the depth of the channel or than the thickness of the substrate. The micro nozzle made by the method illustrated above can provide a reliable and stable interface for electro-spraying.

    摘要： A binder composition for use in making metal parts via a metal powder injection molding process containing the following components: (a) a first polymer with a relatively low solubility parameter such as polyethylene and polypropylene; (b) a second polymer with a relatively high solubility parameter such as polystyrene and poly(methyl methacrylate); and (c) a block copolymer containing blocks of the first and second, or other structurally similar, constituting monomeric units. Examples of the block copolymers include ethylene/styrene copolymer, propylene/styrene copolymer, and isoprene/styrene copolymer, etc. The binder composition is dispersed in an appropriate dispersant, such as an oil or wax, then blended with a metal powder to form a metal powder injection composition. The metal powder injection composition forms a green compact with a predetermined shape and dimension using an injection molding machine. Finally the green compact is sintered to form the final product. The present binder composition eliminates the incompatibility problem which is often encountered when using multi-component binders; this allows the green compact to maintain excellent dimensional and physical integrities both before and during the sintering step and thus ensures the precise dimension of the final products.

    摘要： A fluidic device includes a first material defining a first region, a second material defining a second region that is separated from the first region, and a connector coupled between the first region and the second region. The connector includes a brittle material and has an open end and a closed end, the open end being disposed in the second region, the closed end being disposed in the first region. The first region is closed off from the second region by the closed end of the connector. The connector is configured such that when the closed end of the connector is broken, the connector defines a passage from the first region to the second region.
