摘要： A method and apparatus for fabricating an array of biopolymers on a substrate using a biopolymer or biomonomer fluid, and using a dispensing head. The head has a reservoir chamber and at least one jet which can dispense droplets onto a substrate. The jet includes a capillary delivery chamber communicating with the reservoir chamber, which delivery chamber has an orifice. The jet further includes an ejector which, when activated, causes a droplet to be ejected from the orifice. The method includes loading the head by positioning the head with the orifice adjacent and facing a biomonomer or biopolymer fluid, and providing a load pressure to the reservoir chamber. The load pressure is sufficiently negative such that the fluid is drawn into the reservoir chamber through the orifice and delivery chamber, while simultaneously being insufficient to result in ambient atmosphere entering the delivery chamber through the orifice once the head has been loaded and no further fluid is facing and adjacent the orifice. The head is positioned with the orifice facing the substrate and multiple droplets are dispensed from the head orifice so as to form an array of droplets on the substrate.

摘要： A method and apparatus for fabricating an array of biopolymers on a substrate using a biopolymer or biomonomer fluid, and using a fluid dispensing head. The head has at least one jet which can dispense droplets onto a substrate, the jet including a chamber with an orifice, and including an ejector which, when activated, causes a droplet to be ejected from the orifice. The method includes positioning the head with the orifice facing the substrate. Multiple droplets of the biopolymer or biomonomer fluid are dispensed from the head orifice so as to form an array of droplets on the substrate. A gas flow is directed through a venturi which has a throat opening communicating with the dispensing head chamber. A venturi control valve which particularly communicate with an outlet of the venturi, is adjusted to alter the chamber pressure. The venturi may be driven by a source of inert anhydrous compressed gas which assists in maintaining fluid in the head isolated from moisture.

摘要： Methods and devices for depositing a nucleic acid on a substrate surface are provided. In the subject methods, a thermal inkjet head loaded with nucleic acid fluid composition is positioned in opposing relationship to, e.g. over, a substrate surface. Actuation of the thermal inkjet results in the expulsion of volume of the nucleic acid composition onto the substrate surface. The subject methods and devices find use in a variety of applications, particularly in the preparation of nucleic acid arrays, and more particular arrays of oligonucleotides or polynucleotides, e.g. cDNAs.

摘要： An apparatus for mixing fluids comprises a housing having at least a portion of its interior, for example, a channel, with capillary dimensions and at least one structural member in the interior adjacent an end of the channel. The dimensions of and placement of the structural member are sufficient such that intermittent application of centrifugal force to the interior of the housing causes movement of the fluid therein. The housing may comprise a mixing chamber or area that is in fluid communication with the interior. The apparatus may comprise a mechanism adapted to generate centrifugal force within the housing to cause movement of fluid in the interior of the housing without exit of fluid therefrom.
