Abstract
The present disclosure provides apparatuses, systems, and methods involving a spotter for depositing a substance on a submerged surface. The spotter comprises an outlet cavity defined at least in part by a spotting orifice, a first opening, and a second opening. The spotter also comprises a first conduit fluidly coupled to the first opening and a second conduit fluidly coupled to the second opening. The spotter is adapted so that fluid flowing through the first conduit and the second conduit is communicated among the first opening, the second opening, and a submerged deposition surface when the sealing orifice is sealed against the submerged deposition surface to form a deposition spot on the submerged deposition surface. The submerged deposition surface is within a liquid such that the liquid covers the deposition spot upon removal of the orifice from the deposition surface.
