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.

An applicator assembly may include an applicator member and a pump. The applicator member may include an applicator surface substantially matching a surface of a pipe or fitting. The pump may cause a fluid to flow via one or more channels onto the applicator surface. When the pipe or fitting is positioned within or around the applicator surface the pump causes the fluid to flow between the applicator surface and the surface of the pipe or fitting applying the fluid to the surface of the pipe or fitting.

A method for pre-treating a catheter prior to using the catheter in a medical procedure, and a related apparatus, are provided. The method comprises exposing, in a plasma chamber positioned in a medical care center, and under sterile conditions, intraluminal surfaces and extraluminal surfaces of the catheter to plasma. The plasma is electromagnetically-generated adjacently to the intraluminal surfaces and extraluminal surfaces, thereby rendering, at least temporarily, the intraluminal surfaces and extraluminal surfaces of the catheter hydrophilic.

Provided herein is a composition comprising a poly(alpha-hydroxycarboxylic acid) substantially free of acidic impurities wherein the poly(alpha-hydroxycarboxylic acid) is selected from poly(D,L-lactic-co-glycolic acid), poly(L-lactic acid), poly(D-lactic acid) and poly(D,L-lactic acid). Also provided is a device comprising: a substrate, and a coating wherein the coating comprises poly(D,L-lactic-co-glycolic acid) substantially free of acidic impurities.

The present invention relates to a production technique of a 3D glass candle lamp. Transparent glass is processed, the interior of the glass is formed by a laser method, and by conducting electroplating and color plating on the inner surface and the outer surface of the glass correspondingly, under the condition that a light source of the glass lamp is available, light is reflected by the inner electroplated layer and the outer electroplated layer, and thus clearly-layered 3D patterns are formed at the positions of laser patterns; in addition, the colors of the patterns can change along with plating colors and the color of the light source, and the scene illumination effect is additionally achieved.
