Patent ID: 7690325

Claim:
An apparatus for depositing material onto a surface, the apparatus comprising: a base having a width; a substantially planar elongated beam having a proximal portion extending from the base and a distal portion located a distance from the proximal portion such that the substantially planar elongated beam forms a cantilever with respect to the base, the substantially planar elongated beam having a length of no greater than about 2 mm, the substantially planar elongated beam having a width and being smaller than the width of the base and a terminal end, the width of the substantially planar elongated beam adjacent the terminal end being tapered toward the terminal end; an elongated aperture defined in the substantially planar elongated beam, the elongated aperture at least partially defining an inner surface dimensioned to move liquid along the elongated aperture by passive adsorption, the elongated aperture having a distal portion from which material is deposited onto the surface; and a reservoir in fluid communication with a proximal portion of the elongated aperture, wherein the reservoir is configured to retain the material to be deposited, and wherein the reservoir is wider than the substantially planar elongated beam and is positioned in the base, wherein the substantially planar elongated beam is one of a plurality of substantially planar elongated beams extending from the base to facilitate simultaneous deposition of at least one material onto the surface.
