A device for connection to a female medical connector is disclosed, the device includes a cap, a scrubbing foam, an elastic sealing lip, and an absorbent material. The cap is configured to define a chamber to contain an absorbent material and disinfectant or antimicrobial agent. The cap may include one or more threads adapted to engage with a female luer connector. The device may also include a peelable seal to maintain sterility prior to use and to prevent the disinfectant or the antimicrobial agent from exiting the chamber prior to use. Also described are methods of disinfecting a medical connector.

An air sterilizing device, comprising: a housing (100), forming an air flow path thereon; an ozone generating unit (200), generating ozone particles to be supplied to the air flow path; a filter cartridge (300), receiving ozone generated by the ozone generating unit (200) to discharge bubbles comprising ozone and hydroxyl radicals; an ultrasonic generating unit (400), connected to the filter cartridge (300) to generate ultrasonic waves; an air supply fan (500), configured to supply air to the air flow path of the housing (100); and a power supply unit, configured to supply power for driving the ozone generating unit (200), the ultrasonic generating unit (400), and the air supply fan (500).

Provided herein are portable biocontainment devices for safe and reliable collection of biological samples, including liquid and gas samples. A sample inlet for collecting fluids and/or gases, including oral fluids and expired breath samples, is connected to a container having a climate-controlled container reservoir. One or more sample containers are connected to the sample inlet for collection of samples. The devices are configured for safe transport and handling of samples, while maintaining sample viability, including for relatively long transport periods. Safety components integrated within the device facilitates safe and effective decontamination of contagious samples. In this manner, aborting the sample preservation by decontamination prior to a hazardous release is achieved within the same apparatus.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.

A chemical disinfection process for vehicles using chlorine dioxide and titanium dioxide with calculated re-treatment formulas and schedules based on bacterial infestation data. Systems and methods that include client devices and servers that monitor and control a chemical disinfection process. The system generates a surety arrangement that facilitates re-treatment and electronic notification alerts to chemical solution vendors, dealers and vehicle owners.

A photocatalytic filter includes a filter substrate, the filter substrate being a porous metal, and a photocatalyst fixed to the filter substrate. When a thickness of the porous metal is t (mm) and an average cell number per inch of the porous metal is C (ppi), a product (t×C) of the thickness t and the average cell number C is from 100 or more to 400 or less.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting removably coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.

Described herein are antimicrobial nanoclay comprising two or more cationic antimicrobials. The nanoclay is a phyllosilicate clay and the two or more cationic antimicrobials are individually selected from the group consisting of a quaternary ammonium compound, a metal ion-containing, a cationic chelating agent, a cationic amino acid-based surfactant, a cationic antibiotic, and a cationic compound having a guanidine moiety. The two or more different antimicrobials are incorporated into the nanoclay by a cationic exchange process. Also described are methods for preparing such antimicrobial nanoclays. The antimicrobial nanoclays may be used for conferring antimicrobial activity to an article of manufacture and/or for providing antimicrobial activity to a surface.

A method for preparing a bactericidal film on fiber cloth, comprising cleansing a reel of fiber cloth; placing the reel of fiber cloth into a vacuum chamber; supplying a DC power and a mid-frequency power; introducing argon gas to increase the chamber pressure to 0.3 Pa; position sputtering targets in the following order: silicon target, silicon carbide target, silver target, silicon carbide target, silver target, silicon carbide target and silver target, and then sputtering the targets simultaneously; wherein the silicon targets act as a bonding layer between the bactericidal film and the substrate; stopping the silicon targets, the silicon carbide targets and the silver targets first, and then turning off the argon gas; injecting air into the chamber until the pressure in the chamber and the atmospheric pressure are balanced.

Aspects disclosed herein include a system for generating singlet oxygen in a gas, the system comprising: a substrate; and hexanuclear clusters operably immobilized on at least a portion of the substrate; wherein each hexanuclear cluster comprises a photosensitive octahedral core complex characterized by formula FX1a: M.sub.6X.sub.8 (FX1a); wherein each M is independently Mo, W, or Re; wherein each X is independently a halide anion ligand; wherein the clusters are exposed to the gas and the gas comprises O.sub.2 gas; wherein the clusters are exposed to a light; and wherein each hexanuclear cluster is a photosensitizer configured to generate the gaseous singlet oxygen when irradiated by the light in the presence of the O.sub.2 gas.
