A sterilization method is provided for sterilizing a surgical instrument having an antimicrobial coating formed from applying a solution including a silane quaternary ammonium ion or salt thereof, the method comprising sterilizing the surgical instrument using a low temperature sterilization technique. The low temperature sterilization technique may include low temperature autoclave, exposure to ultraviolet light, exposure to gamma ray radiation, chemical sterilization, or any combination thereof. The chemical sterilization may include sterilization with ethylene oxide.

A method and device for treating contaminated or potentially contaminated items is provided. The method will include the steps of placing the items in a reactor. The reactor is then sealed and ozone or ozonated gas is sent into the reactor. The items are held in the reactor long enough to complete the decontamination process. The reactor is then opened. Next there is a period of passive reaction so that the ozone can be degraded from the pores and surfaces of the items. The device provided herein includes a reactor, an ozone generator, a rack for holding said items; and a monitor for determining the level of ozone in the reactor.

An autonomous drone operated remotely via wireless networks is instructed by its owner flying about in an unoccupied room to activate a system of selectable air and surface disinfection modules. An air purifier captures particles in ambient air and switches on an oscillating motion tubular shaped cage mounted with a plurality of Ultraviolet C spectrum, long range zoom and focusable lens LED projectors to disinfect virus and bacteria. A fan assisted forced air Ozone generator module speeds up disinfecting inconspicuous spots to destroy hidden viruses. Disinfection is completed after the half-life time of dispensed Ozone and an oxygen recovery module rapidly converts residual ozone still in air back to normal oxygen molecules enabling a shortened waiting time for occupants to return to the treated room. A negative ions module subsequently switches on to refresh the air.

Methods of the present invention comprise photoinactivation of catalase in combination with low-concentration peroxide solutions and/or ROS generating agents to provide antibacterial effects.

A method for reducing microbiological contamination in a closed chamber (6), formed by at least two interconnected components (1, 4), by introducing a germicidal medium into the chamber (6).

An apparatus for use in a method of decontaminating a device including a tray. A membrane permeable by a decontaminating fluid is positioned over the top of the tray to form an enclosed space. A lid is secured to the tray and the membrane is positioned between the tray and the lid. A hub assembly is positioned within the tray.

A water treatment system using ozone is disclosed. The system includes a container for holding water, an ozone supply configured to supply ozone, and a water treatment device secured at a lower portion of the container. The water treatment device is configured to disinfect the water using ozone in the container. The water treatment device includes a housing having a plurality of openings and a tortuous porous tube in the housing. The tortuous porous tube is configured to receive the ozone from the ozone supply and distribute the ozone into the water.

The sequential infiltration synthesis (SIS) and Atomic Layer Deposition (ALD) of metal and/or metal oxides on personal medical equipment (PPE). The deposited metal and/or metal oxides imbues antimicrobial properties to the PPE.

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.

Disclosed is a process and a device for sterilizing gas filtration unit, characterized in that the sterilization process includes at least: an application step consisting in circulating, through the gas filtration unit, a gas mixture including hot air and a determined amount of hydrogen peroxide vapor, in which the determined amount of hydrogen peroxide vapor is obtained by sequentially injecting, with a given time interval (t) between two successive injections, a given dose of hydrogen peroxide in the liquid state into the hot air; anda sterilization step consisting, during the time interval (t), in circulating hot air through the filtration unit in order to eliminate, by evaporation, all or some of the hydrogen peroxide deposited on the filtration unit during the application step.
