    摘要: 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. The phase of the inlet flow (from the droplet inlet port (5) and the draft inlet port (4) is used to determine the outlet port (6) flow phase.

    摘要: A method of developing a new coating having a desired performance characteristic with regard to a property of a coating is provided. The method includes the steps of: a) providing an array of coating wells, each well configured for receiving a coating material having a known parameter; b) placing a coating material having the known parameter in each coating well, varying the parameter so as to provide a plurality of coating material having different parameter values in a plurality of coating wells; c) correlating the value of the parameter for the coatings deposited in each of the plurality of coating wells with the position of the coating well in the array, whereby a parameter value is associated with each coating well position in the array; d) applying a coating leveling force to the array of coating wells to level the coating material in the coating wells; e) testing the coatings in the array to analyze the relationship between the position in the array and performance with regard to the property of the coating material, whereby the value of the parameter can be correlated to the performance of the coating with regard to the property of the coating. Optionally, the coatings in the array may be dried while the leveling force is applied. The above combinatorial, high-throughput method of screening candidate coat materials results in a substantial increase in the discovery rate of new coating materials. The moisture barrier characteristics of a film may be determined by providing a vapor sensitive color changing layer, with the film to be measured overlying the vapor sensitive layer, exposing the film to the vapor, and subsequently measuring the color changes.

    摘要: The present invention is drawn to the generation of micropatterns of biomolecules and cells on standard laboratory materials through selective ablation of a physisorbed biomolecule with oxygen plasma. In certain embodiments, oxygen plasma is able to ablate selectively physisorbed layers of biomolecules (e.g., type-I collagen, fibronectin, laminin, and Matrigel) along complex non-linear paths which are difficult or impossible to pattern using alternative methods. In addition, certain embodiments of the present invention relate to the micropatterning of multiple cell types on curved surfaces, multiwell plates, and flat bottom flasks. The invention also features kits for use with the subject methods.
