Abstract: A connection apparatus and an integrated assembly are provided. The connection apparatus comprises a base portion and a flow passage portion which are limited and/or fixedly provided. The connection apparatus comprises a plurality of element connection portions and a plurality of external interfaces that can be used for connecting to a system. The base portion comprises at least two accommodating portions. The flow passage portion comprises at least two modules and a connection part, and the modules are partially located in the accommodating portions. The base portion is provided with a limiting structure that limits the movement of the modules and a notch portion that is at least arranged between two adjacent accommodating portions. The connection apparatus is provided with the connection part that connects at least one group of two adjacent modules, and the connection part is partially located at the notch portion.

Abstract: The present application discloses a method of forming a hydrogel-coated substrate, wherein the hydrogel has antifouling and antimicrobial properties. The method comprises applying an aqueous pre-hydrogel solution to a substrate, polymerizing the aqueous pre-hydrogel solution, thereby forming a coated substrate having a conformal hydrogel coating and a non-conformal hydrogel coating, contacting the coated substrate with a swelling agent, and removing the non-conformal hydrogel coating from the coated substrate, thereby leaving the conformal hydrogel coating on the substrate to form the hydrogel-coated substrate. The aqueous pre-hydrogel solution comprises a monomer with antimicrobial activity, a monomer with antifouling activity, and either a polymer, oligomer, or macromer which, when polymerized together, form a hydrogel. Also disclosed is a coated substrate and a hydrogel coating.

Abstract: Microorganisms can contaminate a number of surfaces, such as those of consumer products. The present disclosure describes compositions and methods of manufacturing and using the same for providing biocidal activity on such surfaces. The compounds of the present invention can comprise a sample of a polymer. The polymer can comprise a repeating unit having a side chain that comprises a nitrogen-containing heterocycle. The nitrogen-containing heterocycle can form an N-halamine and exhibit the biocidal activity.

Abstract: The present application relates to copolymers of N-halamine (HA) and dopamine (DMA) and their method of formation. The HA and DMA are present in the copolymer in a ratio of 0.4:9.6 to 9.6:0.4 (HA: DMA). The copolymers can be used in novel antimicrobial compositions that can be coated, and covalently bonded to surfaces such as metal, plastic, glass, or paint surfaces. The coating provides a rechargeable antimicrobial surface with the treatment of a halogen. The coating thickness and halogen content can be tuned by adjusting the formulation and crosslinking the coating.
