    摘要: A polymer synthesis apparatus (20) for building a polymer chain including a head assembly (21) having an array of nozzles (22) with each nozzle coupled to a reservoir (23) of liquid reagent (24), and a base assembly (25) having an array of reaction wells (26). A transport mechanism (27) aligns the reaction wells (26) and selected nozzles (22) for deposition of the liquid reagent (24) into selected reaction wells (26). A sliding seal (30) is positioned between the head assembly (21) and the base assembly (25) to form a common chamber (31) enclosing both the reaction well (26) and the nozzles (22) therein. A gas inlet (70) into the common chamber (31), upstream from the nozzles (22), and a gas outlet (71) out of the common chamber (31), downstream from the nozzles (22), sweeps the common chamber (31) of toxic fumes emitted by the reagents. Each reaction well (26) includes an orifice (74) extending into the well (26) which is of a size and dimension to form a capillary liquid seal to retain the reagent solution (76) in the well (26) for polymer chain growth therein. A pressure regulating device (82) is provided for controlling a pressure differential, between a first gas pressure exerted on the reaction well (26) and a second gas pressure exerted on an exit (80) of the orifice, such that upon the pressure differential exceeding a predetermined amount, the reagent solution (76) is expelled from the well (26) through the orifice (74). A method of synthesis of a polymer chain in a synthesis apparatus (20) is also included.

    摘要: Disclosed are systems and methods involved in extreme high throughput screening of compounds which have an affinity for a biological target. The system is based on a capillary bundle with two distinguishable ends wherein capillaries on one end are connected to compounds stored in discrete reservoirs and capillaries on the other end are bound and processed to form a two dimensional microarray. A capillary bundle having reaction wells for hybridization and compound reaction in one end of the capillaries is disclosed. The capillaries may be light-conducting. Also disclosed are various methods of identifying a target compound in a liquid using this capillary bundle as well as methods of fabricating the bundle. A novel surface tension guided reaction chamber is also provided. Methods and chemistry for fabrication and use of a surface tension guided reaction chamber in binding and hybridization assays are also disclosed. Methods and systems for precise metering of fluids within the capillaries and at the reaction chambers, including the surface tension guided nullvirtualnull reaction well is provided. Methods for performing high throughput screens using optical fiber lined capillaries of the invention are also provided. The capillary arrays are used with both liquid probes as well as probes immobilized on the walls of the capillary.

    摘要: A method and system to deposit rapidly, accurately and efficiently liquid droplets onto a sample plate. A liquid from which the droplet is formed contains sample molecules, matrix molecules or a mixture of both sample and matrix molecules. A sample plate is positioned with respect to a position below a portion of the liquid, such as a droplet. A power supply forms an electric field between the sample plate and the liquid, which pulls the droplet to a target location on the sample plate. A plurality of capillary columns is provided for simultaneous or successive multiple depositions via application of one or more high voltage pulses between the liquid sample array and a sample plate.
