Abstract

The present disclosure provides apparatuses, systems, and methods involving a spotter apparatus for depositing a substance from a carrier fluid onto a deposition surface in an ordered array. The spotter apparatus includes a loading surface, including a first well and a second well, and a different outlet surface, including a first opening and a second opening, where a first microconduit fluidly couples the first well with the first opening and a second microconduit fluidly couples the second well with the second opening. An overlay is sealed to the outlet surface and penetrated by a deposition channel that is situated to communicate carrier fluid among the first opening, the second opening, and the deposition surface when the overlay is pressed against the deposition surface.
