Abstract:
1. A microarray system, comprising: a microarray formed on a planar substrate; an incubation chamber comprising an enclosed space formed around said microarray, wherein said incubation chamber is connected to one inlet and one outlet channel; a one-way valve for loading a liquid sample into said incubation chamber, wherein said one-way valve is connected to said incubation chamber through said inlet channel; and a waste chamber in fluid communication with said incubation chamber through said outlet channel, wherein said incubation chamber comprises a plurality of interior surfaces including a bottom surface on which said microarray is formed and a top surface that faces said microarray, wherein said top surface is a hydrophilic surface and said bottom surface is a hydrophilic surface and wherein said top and bottom hydrophilic surfaces overcome the surface tension of a water-based liquid and allows complete filling of said incubation chamber with said water-based liquid, wherein said outlet channel comprises an inlet section, a funnel shape connecting section, and an outlet section, wherein said inlet section has a diameter that is larger than a diameter of said outlet section, and wherein said waste chamber has a volume that is larger than a volume of said incubation chamber and comprises an absorbent capable of wicking liquid from said incubation chamber, wherein said incubation chamber is formed by placing a gasket around said microarray and covering said gasket with a hydrophilic tape or a hydrophilic film, wherein said top surface consists of the hydrophilic tape or the hydrophilic film.
