A method for making a colorant film providing eye care includes following steps of providing a plurality of microcapsules containing hydrogen peroxide aqueous solution; mixing a hydrophilic monomer, a cross-linking agent, and an initiator to form a mixture; mixing the microcapsules, the mixture, a pigment, and a solvent to form a colorant material; printing the colorant material into a mold; and heating or irradiating the colorant material in the mold to copolymerize the hydrophilic monomer, the initiator, and the cross-linking agent. A colorant film, and the manufacture of an ophthalmic lens are also provided.

Provided are articles having a substrate and a polymer matrix. The polymer matrix includes a hydrogen peroxide releasing compound dispersed within the polymer matrix. The polymer matrix is provided on a surface of the substrate. Also provided are methods of forming the articles of the disclosure and kits for preparing the articles of the disclosure.

A contact lens for the human eye includes a matrix and polymer nanocapsules mixed in the matrix. The polymer nanocapsule is calculated to decompose by chemical reaction and thereby release oxygen, to prevent corneal hypoxia. A material for making a contact lens is also provided.

Fibers for generating antimicrobial activity are described. The fibers comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance that includes a substrate for the enzyme, wherein the enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the unrefined natural substance. In the presence of sufficient free water, the enzyme converts the substrate to release hydrogen peroxide, which is effective against a wide range of microbes. Wound dressings and compositions comprising the fibers are also described, as is use of the fibers, wound dressings and compositions, particularly for wound healing.

This invention pertains to a polymeric composition and an antimicrobial composition, each comprising a superabsorbent polymer (SAP), such as used in diapers and sanitary napkins, and peroxide. The superabsorbent material can be made by the process of treating a preformed SAP, such as a crosslinked polyacrylate salt, with a treatment solution comprising hydrogen peroxide dissolved in water, followed by drying. The resulting superabsorbent material has strong antimicrobial activity. Optionally, the treatment solution may also contain a metal salt, including those of zinc, zirconium, and magnesium.

The present disclosure relates to a novel oxygen-generating biodegradable mesh material, and to methods of making and using the novel oxygen-generating biodegradable mesh material. More specifically, a novel surgical mesh has been developed, wherein the surgical mesh has a flexible basic structure and comprises a plurality of pores, wherein the surgical mesh has a first face and a second opposite face, wherein the surgical mesh is made of a substantially homogeneous material comprising a biodegradable polymeric material and an oxygen-generating material.

Cellulosic pulp structures integrating unreacted quantities of an inorganic peroxide and a destabilizing acid, as binary components of an odor control system, absorbent articles incorporating such structures, and various methods of forming the same, are disclosed herein. The components are adapted to react in the presence of an aqueous fluid to produce hydrogen peroxide, thereby providing an antimicrobial and odor mitigating effect.

The present invention comprises methods and compositions for delivery devices More particularly, the present invention comprises methods and compositions for devices comprising a matrix comprising a polymer network and a non-gellable polysaccharide having oxygen and optionally active agents incorporated therein. The matrix may be formed into any desired shape for treatment of compromised tissue or for delivery of oxygen to a localized environment.

The present disclosure provides biophotonic compositions containing halogen ions and/or halogen salts and methods useful in phototherapy.
