The disclosure is directed at a large-area monolayer of solvent dispersed nanomaterials and method of producing same. The method of the disclosure includes dripping a nanomaterial solvent into a container filled with water whereby the nanomaterial being dripped collects at the air-water interface to produce the large-area monolayer. In one embodiment, different nanomaterial solvents can be dripped, at predetermined intervals such that the resulting large-area monolayer includes at least two different nanomaterials.

A method for manufacturing an electronic device is disclosed. In the method, a first shell and a second shell are formed. The first shell and the second shell are assembled with each other to form a casing for receiving an electronic module. The two opposite ends of the casing respectively have a first opening and a second opening. The first opening and the second opening are aligned with each other along an extending direction. A seam is located at an outer surface of the casing and between the first shell and the second shell. A paint level is formed on the outer surface of the casing to cover the seam. The casing is moved toward a water transferring film along the extending direction which is vertical to the water transferring film for connecting the water transferring film with the paint level.

A method for producing an assembly of particles bound by a substrate, including: making a compact film of solid particles floating on a carrier liquid, the solid particles potentially holding objects between them; spraying particles onto a face of the compact film opposite to the one immersed in a carrier liquid, to create a substrate-forming-skin adhering to the solid particles; and extracting an obtained assembly outside the carrier liquid.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates on demand for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

In an example, a method including dispensing a liquid onto a first portion of a surface of a substrate and dispensing a solution comprising colloidal spheres onto a second portion of the surface of the substrate. The method additionally includes agitating the colloidal spheres to disperse the colloidal spheres along the first portion and the second portion of the surface of the substrate and directing air flow above the colloidal spheres inducing rotation of the colloidal spheres. In another example, a method includes positioning a retaining ring on a surface of a liquid above a substrate below the surface of the liquid and dispensing a solution comprising colloidal spheres onto the surface of the liquid within a surface area of the retaining ring. The method further includes agitating the surface of the liquid and the colloidal spheres to disperse the colloidal spheres along the surface area of the retaining ring.
