An ethylene oxide sterilization sensor, and method of use, wherein the sensor includes: a heat-shrinkable film; an acid-functional porous sorbent in thermal contact with the heat-shrinkable film; and an acid having a boiling point above 120° C. and a pKa of no greater than 2.5, wherein the acid is impregnated in or covalently attached to the porous sorbent.

A method of lamellar corneal graft implantation is disclosed herein. The method includes the steps of: (i) forming one or more intrastromal incisions in a cornea of an eye of a patient; (ii) removing a cut portion of the cornea defined by the one or more intrastromal incisions from the eye of the patient; (iii) applying laser energy to a lamellar corneal graft using an excimer laser so as to modify the refractive power of the lamellar corneal graft, the lamellar corneal graft being in the form of a autologous corneal graft or a homologous corneal graft; and (iv) implanting the lamellar corneal graft into the eye of the patient in a location previously occupied by the cut portion of the cornea so as to correct the refractive power of the eye of the patient.

The invention concerns coating compositions for medical devices or medical implants comprising a polymer which is soluble in water or water-alcohol solutions, the polymer made from monomers comprising: (a) at least one monomer that is a photo radical generator, and (b) at least one monomer comprising one or both of (i) ethylenic monomers comprising at least one acidic group and (ii) one or more of acrylates or acrylamides; wherein the molar ratio of one or both of (i) ethylenic monomers comprising at least one acidic group and (ii) one or more of acrylates or acrylamides to photo radical generator group is 20:1 to 500:1.

This invention discloses novel particulate compositions made by modifying Superabsorbent Polymer (SAP) and other high surface area substrates to create granules that exhibit broad-spectrum antimicrobial and enzyme-inactivating properties, and that can directly neutralize certain malodorants and other undesirable chemical entities, such as toxins. This is accomplished by the direct interaction of the modifying moieties with: (1) vital components of bacteria, fungi, yeasts, and viruses; (2) enzymes, such as those that are responsible for the generation of malodorants and other toxic volatile compounds; and (3) certain malodorants and other undesirable compounds that are susceptible to oxidative or halogenation reactions that can neutralize their odors or toxicities. Chemical modifications of granular materials are accomplished by exposure to organic solvents containing soluble or dispersible N-halamine.

Described is method for the sanitizing treatment of a textile product comprising a step of providing a textile product, a step of washing said textile product and a subsequent sanitizing treatment step, said sanitizing treatment step comprising the application on said textile product of a mixture based on methylisothiazolinone (MIT) and methylchloroisothiazolinone (CIT) and water.
