Coating compositions, coated articles including the coating compositions, and methods of making the coating compositions and coated articles are provided. In some aspects, the coating compositions are applied to a substrate having nitric oxide-releasing properties. The coating compositions can include copolymers having crosslinking agents that can be activated with mild UV light (about 345 nm to 365 nm) to avoid damaging the substrate while creating strong covalent bonds to the substrate. The copolymers can include hydrophilic repeat units, and in particular zwitterionic repeat units such as repeat units containing phosphorylcholine groups. In some aspects, the coating compositions are applied to a surface of a polymer substrate, wherein the polymer substrate had nitric oxide releasing properties. The coating compositions and the coated articles can have antifouling, antithrombotic, and/or antibacterial properties.

Surfaces and coating compositions having antifouling, antithrombotic, and antibacterial properties and methods of making

Nitric oxide-releasing materials, methods of making nitric oxide-releasing materials, and uses of nitric oxide-releasing materials are provided. The nitric oxide-releasing materials include a mesoporous silica core and an outer surface having a plurality of nitric oxide donors. In an exemplary aspects, the nitric oxide-releasing material includes a mesoporous diatomaceous earth core, and an outer surface having a plurality of S-nitroso-N-acetyl-penicillamine groups covalently attached thereto. Uses of the nitric oxide-releasing materials can include coatings for medical devices such as catheters, grafts, and stents; wound gauzes; acne medications; and antiseptic mouthwashes; among others.

Mesoporous nitric oxide-releasing silica particles, methods of making, and uses thereof

The present disclosure provides for modified antibiotic compounds, methods of making modified antibiotic compounds, methods of use, products including modified antibiotic compounds, and the like. The modified antibiotic compound comprises a nitric oxide release agent covalently attached to an antibiotic molecule, such as S-nitroso-N-acetylpenicillamine covalently attached to ampicillin.
