Publication number: 20140121132Abstract: The present invention relates to a system for producing a nucleic acid molecule imaging array for use in high resolution imaging of individual nucleic acid molecules. The system includes a micro/nanostructured capture array having a hydrophobic surface having topographical features effective to assist in capillary-based trapping and elongation of individual nucleic acid molecules. The system also includes a transfer platform having a support and a hydrophobic substrate layered on the support. The transfer platform is effective to receive and capture, through solvent mediation, the trapped and elongated individual nucleic acid molecules from the micro/nanostructured capture array. The present invention also relates to a nucleic acid molecule imaging array, a transfer platform for use in preparing a nucleic acid molecule array, and a kit for producing a nucleic acid molecule imaging array for use in high resolution imaging of individual nucleic acid molecules.Type: ApplicationFiled: March 12, 2012Publication date: May 1, 2014Applicant: CORNELL UNIVERSITYInventors: Aline Cerf, Harold G.

Publication number: 20140066333Abstract: The invention provides a method of printing, onto a substrate (12), an array (14) of spots of reagent compositions for use in a chemical and/or biochemical analysis. The method includes displacing an array of reagent composition containing capillary tubes (22) arranged alongside one another from an inoperative position to an operative position in which open ends of the capillary tubes (22) simultaneously impinge against a substrate and thereafter displacing the array of tubes (22) from the operative position back to the inoperative position. The invention extends to a printing apparatus (10), a method of printing a layered array of spots of reagent compositions, a method of introducing reagent compositions into the tubes, a reagent introducing device for introducing reagent compositions into the tubes and a printing installation which includes the printing apparatus (10) and the reagent introducing device.Type: ApplicationFiled: November 8, 2013Publication date: March 6, 2014Inventor: Neil Emans

Patent number: 8663397Abstract: The embodiments describe methods for controlling the particles generated when cleaning and drying a wafer in a spin rinse dryer (SRD) module. In some embodiments, the substrate surface is cooled by dispensing deionized (DI) water across the surface of the substrate, while the substrate rests on the SRD chuck. In addition, a method for controlling the particles generated when sleeves in a processing module or SRD contact a substrate surface during a clamping operation or when the sleeves are removed from the substrate surface is provided. A bottom edge or lip of the sleeves and/or the surface of the wafer contacting the sleeve is wetted during clamping/unclamping operations. Alternatively, the substrate may be wetted prior to clamping/unclamping operations.Type: GrantFiled: October 22, 2012Date of Patent: March 4, 2014Assignee: Intermolecular, Inc.Inventors: Satbir Kahlon, Jeffrey Chih-Hou Lowe, Frank C.

Publication number: 20140051604Abstract: A multi-port liquid bridge (1) adds aqueous phase droplets (10) in an enveloping oil phase carrier liquid (11) to a draft channel (4, 6). A chamber (3) links four ports, and it is permanently full of oil (11) when in use. Oil phase is fed in a draft flow from an inlet port (4) and exits through a draft exit port (6) and a compensating flow port (7). The oil carrier and the sample droplets (3) (“aqueous phase”) flow through the inlet port (5) with an equivalent fluid flow subtracted through the compensating port (7). The ports of the bridge (1) are formed by the ends of capillaries held in position in plastics housings. The phases are density matched to create an environment where gravitational forces are negligible. This results in droplets (10) adopting spherical forms when suspended from capillary tube tips. Furthermore, the equality of mass flow is equal to the equality of volume flow.Type: ApplicationFiled: October 18, 2013Publication date: February 20, 2014Applicant: STOKES BIO LIMITEDInventors: Mark Davies, Tara Dalton, Julie Garvey, Kieran Curran, Damian Curtin
