A fluid applicator device includes an applicator body having a surface that is generally planar. A plurality of aligned applicator teeth extend from said applicator body. Each applicator tooth extends longitudinally from said applicator body along a length from a base of the applicator tooth proximate to the applicator body to a tip of the applicator tooth distal to the applicator body. At least one applicator tooth of the plurality of aligned applicator teeth has a width that is greater at the base than at the tip. A method for depositing a liquid sample on a substrate using the fluid applicator device is also disclosed.
