An apparatus for generating an effective concentration of ozone for killing bacteria, viruses and other harmful microorganisms includes a housing having an ozone chamber defining an enclosed space for containing elevated concentrations of ozone. The ozone chamber includes ports providing access to the interior of the ozone chamber. A second chamber of the apparatus houses an ozone reactor. A programmable control circuit operates both the ozone reactor and a pump for directing ambient air to the ozone reactor. The control circuit includes a motion detector mounted in the ozone chamber for activating the ozone generator of the invention and initiating the generation of ozone directed into the ozone chamber of the apparatus of the invention.

The present invention is directed to compositions and methods of treating bacterial, viral, fungal diseases; inflammation or inflammatory-related disorders; pain; and skin conditions. The composition comprises an organic solvent extract, which is prepared by the method comprising the steps of: (a) mixing methionine with water, (b) adding an aqueous hypochlorite solution to the methionine solution and mixing, (c) adding a water-immiscible organic solvent to (b) and mixing, and (d) separating the organic solvent phase from the water phase to obtain the organic solvent extract.

An integrated, self-contained hand sanitizer station is provided by this invention. The enclosure of the station may be located in a public venue, and conveniently dispenses wet wipe towelettes for people to clean their hands with a trash receptacle contained within the station for ready disposal of the towelettes by the patrons after their use. By making a good hand hygiene available to customers, a merchant or public authority can help to reduce germs, viruses, and bacteria that can otherwise cause the spread of infectious illnesses.

The invention relates to nanoliposome human papillomavirus (HPV) resistant and gynecological inflammation pathogen resistant specific complex IgY and a combined preparation for the same. Laying poultry is preferred to respectively prepare laying poultry for immunity of tumor somatic cells, viral protein complex antigens, gene recombination protein antigens and bacterial virus complex antigens; and human papillomavirus resistant special IgY and gynecological inflammation pathogen resistant specific IgY undergo affinity chromatography and purification and are converted into nanoliposomes, and then the nanoliposome special complex IgY is prepared. The nanoliposome human papillomavirus (HPV) resistant and gynecological inflammation pathogen resistant specific complex IgY and the combined preparation for the same have the advantages that: the nanoliposome technology is applied to increase the infiltration capacity and the prolongation effect and improve the curative effect. The nanoliposome human papillomavirus (HPV) resistant and gynecological inflammation pathogen resistant specific complex IgY and the combined preparation for the same can be prepared into various vaginal spraying agents, other spraying agents, lotion, gel, capsules, suppository, vaginal membranes, tablets, effervescent tablets, ointment, cream and so on. The nanoliposome complex IgY can infiltrate into a vagina mucosa to effectively remove HPV viruses and gynecological inflammation pathogens which are absorbed on the vaginal surface layer and in the vagina mucosa, is absorbed through the vagina mucosa and enters into the body to give play to the functions of prevention and treatment, and also can effectively prevent recrudescence.

The present invention discloses a composition and method of providing ionic forms or compounds of any combination of three metals to produce a product that can be used as a antimicrobial as defined by the U.S. Environmental Protection Agency (EPA) such as a hard surface disinfectant and as a foliar spray or water treatment for the control of various diseases in garden row, field and tree crops, on hard surface areas such as equipment from infected fields or in hospitals, homes, etc. as well as against a wide range of human, plant and animal diseases. Additionally, the composition of the present invention is able to be used to coat and otherwise treat and disinfect food products such as but not limited to fish and shellfish, meat, milk, poultry, eggs and irrigated crops (both food and nonfood crops) as well as non food products as defined in the EPA exemption from tolerance for copper and copper products. The composition may include inerts such as surfactants, detergents and buffers to adjust the pH. The composition remains soluble in water and is useful efficacious against the spread of bacteria, viruses and fungi and other pathogens within a source of water such as a reservoir or pool. Alternatively, the composition may be in aerosolized, misted, vaporized, fogged, humidified forms to produce micronized particles which are able to remain in suspension in the air for long periods of time in order to act on air-borne fungal spores and / or pathogens.

Herein disclosed are rapid real-time isothermal multiplex methods of detecting, identifying and quantifying bacterial, viral, and protozoan nucleic acids in a sample. These include contacting the sample with two or more sets of pathogen-specific reverse transcription loop-mediated isothermal amplification primers and novel oligofluorophores specific for the target bacterial, viral, and parasitic nucleic acids of interest such as human immunodeficiency virus, Ebola virus, Marburg virus, Yellow fever virus, hepatitis-B virus, Lassa fever virus, Plasmodium, hepatitis-C virus, hepatitis-E virus, dengue virus, Chikungunya virus, Japanese Encephalitis virus, Middle Eastern Respiratory Syndrome Corona virus, Mycobacterium, West Nile virus, Cytomegalovirus, Parvovirus, Leishmania, Trypanosoma, and Zika virus nucleic acids, under conditions sufficient to produce detectable real-time amplification signals in about 10 to 40 minutes. The amplification signals are produced by pathogen-specific fluorogenic labels included in one or more of the primers. Also, novel reaction and sample lysis buffers, primers, and kits for rapid multiplex detection, quantification, and identification of bacterial, viral, and protozoan nucleic acids by real-time isothermal amplification are herein disclosed.

This invention discloses a nanometer immune magnetic particle process and its application. Its nanometer particle is to cover dextran in the surface of the nanometer degree of Fe#-[3] O#-[4]. The dextran is connected with the characteristics antibody.

The nanometer immune magnetic particle can be used in isolation bacteria, virus, parasite, and cell and biological molecule.

The invention discloses an air purifier through a photocatalyst ultraviolet hydroxyl radical generator and a multiple-filtration system. Firstly, indoor air enters the photocatalyst ultraviolet hydroxyl radical generator through a coarse filtering film; water vapor in the air is made to rapidly generate a large quantity of hydroxyl radicals with extremely strong oxidation through ultraviolet rays with specific wavelength under the catalyzing action of nano-TiO2; the hydroxyl radicals can rapidly kill bacteria, viruses and mould in the air to achieve oxidation decomposition of volatile organic compounds in the air and can also achieve oxidation decomposition of other pollutants generated by natural and human factors, such as methane, nitrogen monoxide, hydrogen sulfide, ozone and other toxic and harmful gases (SO2, O3 and NH3); then the air treated in the former step is subjected to deep filtering through a nanometer cellulose acetate membrane, and residual bodies of pathogens such as tiny bacteria, viruses, mould and dust mite and particulate matter of PM2.5 and the like are adsorbed and filtered out.
