Manufacturing method for focusing devicenof micrometric scale fluid.n n n The object of the present invention is anmanufacturing procedure for a device intended forndispersion of a fluid, called focused, in another or others, callednfocusing, accurately and controlled on a micrometric scalenusing the technique known as "flow focusing" andndevices manufactured according to that procedure. The object methodnof the present invention allows the manufacture ofna device capable of producing coaxial fluid currentsn(three-dimensional encapsulation). The manufacturing process, based onnstandard techniques in microsystem technology (systemsnmicroelectromechanical or MEMS, Micro Electro Mechanical Systems),nallows mass production of dispersion devices withnmicrometric precision, at low cost, and with a very large sizenreduced.n n n The manufactured device can easily benintegrated in two-dimensional matrices, being able to create flowsncoaxial in the direction perpendicular to the matrix ofndispositives. |
