Coating compositions that may be used in combination with UV light for sterilization include a polyurethane component and nanoparticles having an average particle size of from about 30 nm to about 400 nm. The nanoparticles absorb light having a wavelength of from about 100 nm to about 290 nm, and are present in an amount of less than about 25 weight percent of total solids in the coating composition.

System and methods for dispensing a residual surface sanitization or disinfection formulation on a surface. The system may include a formulation and a device. The device includes a sprayer configured to spray the formulation onto a surface as a coating. The spray has a Dv.sub.50 particle size distribution of less than about 150 m and the coating has a residual coating coverage efficiency of at least 30 cm.sup.2/mm.sup.2. Additionally, the coating covers a majority of the surface and provides a durable coating on the surface for a time period therefore providing residual sanitization or disinfection to the surface over the time period.

Described herein are nitric oxide-releasing compositions. In one aspect, the nitric oxide releasing polysiloxane comprises a polysiloxane backbone with one or more nitric oxide releasing moieties pendant to the polysiloxane backbone. The nitric oxide-releasing compositions possess antibacterial properties with respect to both Gram-positive and Gram-negative bacteria. The ease of synthesis and excellent antibacterial effects against both Gram-positive and Gram-negative bacteria without resistance and serious leaching concerns makes the nitric oxide-releasing compositions useful as lubricants for medical devices and other articles where it is desirable to reduce or prevent bacterial infection.

Provided are compositions and methods related to modified lubricins, methods of making the modified lubricins, and methods of using the modified lubricins for coating a variety of inanimate objects, and for prophylaxis and/or therapy of disorders where enhanced lubrication of one or more parts of a human or non-human mammal is desirable.

A device for purifying drinking water in multiple stages by combining orthogonal purification technologies in one module is described, where the device comprises a housing, a water inlet opening, a water outlet opening, a hollow cylinder which is filled with activated carbon, and a hollow cylinder with a semipermeable wall, wherein the hollow cylinder contains a chelating bactericidal gel or a chelating and bactericidal gel for removing heavy metals or bacteria or for removing heavy metals and bacteria.

Provided herein is a solid article for sustained release of one or more hydrophobic materials, comprising at least 5 wt. % of one or more hydrophobic materials embedded in a gel matrix, wherein said gel matrix is formed from a chemically cross-linked polyester material.

Process for the preparation of particles with antibacterial coating, which comprises the following steps: (a) providing an aqueous suspension containing a polyamine, a crosslinker and a porous organic or inorganic carrier material in particle form at a temperature lower than or equal to 10 C. in a mixer for coating the inorganic carrier material with the polyamine; (b) crosslinking the organic polymer in the pores of the inorganic carrier material and simultaneously removing water.

A polyester coacervate capable of disrupting biofilms formed on substrates and methods of treating contaminated substrates to disrupt and remove biofilms using polyester coacervates without the need for antibiotic therapies or mechanical disruption. The polyester coacervate exhibits tunable viscosity, hydrophobic/hydrophilic, and interfacial properties to disrupt and remove a broad range of biofilms formed on a broad range of substrates.

A reusable urinary catheter assembly comprises a storage container defining a cavity, a hydration liquid and a reusable urinary catheter. The hydration liquid includes a disinfection medium and a hydrophilic polymer. The viscosity of the hydration liquid is 40 cP or lower. The reusable urinary catheter includes a shaft, and at least a part of the shaft is provided with a hydrophilic surface. During storage, the shaft is enclosed within the cavity in a storage position. The hydration fluid hydrates and regenerates the hydrophilic surface and disinfects the catheter. The catheter is configured to be repeatedly inserted into and removed from the storage container.
