A method of applying a blocking composition (116) on a substrate for an assay (20) comprises: providing a substrate for an assay (20), wherein the substrate for an assay comprises a solid substrate provided with a plurality of discrete spots of a biological material on a surface thereof; and spraying the blocking composition (116) onto the substrate (20) as particles or droplets having a diameter being less than the diameter of the printed spots of biological material.

Systems and methods for preparing covalent organic framework (COF) thin films is disclosed herein. The systems and method utilize COF colloidal inks, having a diameter of 10-1000 nm, expelled through a nozzle onto a substrate to prepare the COF thin film. The plurality of COF colloidal ink droplets have an effective deposition diameter from the nozzle onto a masked or unmasked substrate, where the substrate may be heated to an effective COF deposition temperature.

Provided is a pattern forming apparatus which may form a pattern on a substrate with high precision by using a material including an organic material, the pattern forming apparatus including: a capillary facing a grounded substrate and capable of storing a solution including a sample; a power source applying a voltage to the capillary; a stencil mask disposed between the capillary and the substrate, and including an opening through which the sample passes; and a cross-direction actuator moving the stencil mask in a cross direction crossing a direction in which the sample passes.

Embodiments of the present disclosure provide a main mask, a mating mask, and a mask assembly. The mask assembly includes a main mask having an evaporation area and a mating mask having a mating area. An effective evaporation area of the main mask corresponds to a display area of a display panel. A first mating area of the mating mask is provided with a first mating opening, and an orthographic projection of the first mating opening on the mating mask completely covers an orthographic projection of the effective evaporation opening on the mating mask. A second mating area of the mating mask shields an ineffective evaporation opening in an ineffective evaporation area of the main mask.
