In Situ Generation Of Agent Other Than Aldehyde Or Glycol Patents (Class 422/29)
  • Patent number: 11097029
    Abstract: Disclosed is a method of sterilizing an article by sequentially exposing the article under vacuum first to a gaseous conditioning agent for forming radicals and then to a sterilant. The preferred conditioning agent is hydrogen peroxide and the preferred sterilant is ozone. The chamber is initially evacuated to a first vacuum pressure and then sealed for the remainder of the sterilization process and during all sterilant injection cycles, without removal of any component of the sterilization atmosphere, which means without any measures to reduce the water vapor content. Keeping the chamber sealed and maintaining the conditioning agent and the radicals generated thereby in the chamber for the sterilization with sterilant results in a synergistic increase in the sterilization efficiency and allows for the use of much lower sterilant amounts and sterilization cycle times than would be expected from using the conditioning agent and the sterilant in combination.

  • Patent number: 9082700
    Abstract: An ultraviolet treatment method is provided for a metal oxide electrode. A metal oxide electrode is exposed to an ultraviolet (UV) light source in a humid environment. The metal oxide electrode is then treated with a moiety having at least one anchor group, where the anchor group is a chemical group capable of promoting communication between the moiety and the metal oxide electrode. As a result, the moiety is bound to the metal oxide electrode. In one aspect the metal oxide electrode is treated with a photoactive moiety. Exposing the metal oxide electrode to the UV light source in the humid environment induces surface defects in the metal oxide electrode in the form of oxygen vacancies. In response to the humidity, atmospheric water competes favorably with oxygen for dissociative adsorption on the metal oxide electrode surface, and hydroxylation of the metal oxide electrode surface is induced.

In various respects, the invention is directed to an insulated system that reduces heat loss from catalyzed neutralization of a disinfecting solution resulting in an increased temperature of the disinfection solution during the disinfection process and neutralization of the disinfection solution. The increased temperature increases the kill rate (i.e., better reduction) of microorganisms present on the lenses, and increases the neutralization rate of the disinfection solution. Increase of the kill rate allows better reduction of microorganisms resistant to elimination using previous systems and methods, (e.g., Acanthamoeba cysts), and decreases the amount of time as compared to previous systems and methods necessary to reduce microorganisms to acceptable levels.

  • Publication number: 20140334976
    Abstract: It is intended to provide a sterilizer, an oral cavity sterilizer, a sterilization method, a sterilization apparatus, and a sterilizer evaluation method capable of enhancing a sterilization effect. The sterilizer including hydrogen peroxide and a catalase activity inhibitor containing scutellaria or green tea is brought into contact with a sterilization target. Next, the sterilization target is irradiated with light having a wavelength of 350 nm to 500 nm using a light emitting device formed of a semiconductor laser. By the light irradiation, the hydrogen peroxide is photolyzed to generate hydroxy radicals, and sterilization is achieved by the thus-generated hydroxy radicals.

  • Patent number: 8871146
    Abstract: An object of the present invention is to efficiently sterilize microorganisms present in or on a surface of a liquid. Plasma is generated in a vicinity of or in a manner to make contact with a liquid whose pH value is adjusted to become 4.8 or lower, more preferably 4.5 or lower. The plasma is generated in an atmospheric gas containing nitrogen, e.g., in the air. Superoxide anion radicals (O2?.) that are generated by the plasma react with protons (H+) in the liquid to form hydroperoxy radicals (HOO.). Further, nitrogen and oxygen included in the air are combined together by the action of plasma to form nitrogen oxide such as nitric oxide (NO.). The nitric oxide (NO.) combines with the hydroperoxy radicals (HOO.) to become peroxynitrite (ONOOH(ONOO?)) having a high microbiocidal activity.
