Compositions and articles comprising a non-woven matrix for use as anti-microbial filters are provided. In some embodiments, the non-woven matrix comprises nanofibers suitable for capturing a droplet comprising a microbe (e.g. a virus particle). In some embodiments, the non-woven matrix comprises a biocide suitable for reducing propagation and/or inactivating a microbe.

Multipurpose product with prolonged antimicrobial action comprising at least one quaternary ammonium and copper nanoparticles in non-oxidized metallic state (Cu.sup.0), where copper nanoparticles in non-oxidized metallic state (Cu.sup.0) are found nucleated in at least one quaternary ammonium. A method for producing a multipurpose product with prolonged antimicrobial action.

Disclosed are alcohol-free personal care compositions, e.g., hand sanitizers, that effectively deposit topically active natural antibacterial compounds (e.g., carvone and thymol) on the skin. In one aspect the disclosure relates to personal care compositions comprising, essential oils (e.g., thymol and carvone), in combination with a carboxylic acid, (e.g., lactic acid), into an alcohol-free product that leads to unexpected benefits with respect to bacterial reduction, e.g., with respect to reduction of S. aureus and E. coli bacteria.

Disclosed herein are methods of making pure chalcogenide (e.g., selenium, tellurium, or selenium/tellurium) nanoparticles by irradiating chalcogenide pellets by nano-second laser ablation using chitosan as a capping agent to form chitosan chalcogenide nanoparticles (CS-CgNPs). CS-CgNPs and methods of using such particles are also disclosed herein, such as antimicrobials and antimicrobial coatings effective against biofilms.

An antibacterial and deodorizing leather includes a leather body and an antibacterial and deodorizing layer. The antibacterial and deodorizing layer includes a water-based foaming material and an antibacterial deodorant. The water-based foaming material and the antibacterial deodorant are mixed and arranged on the leather body and then bonded with the leather body by hot pressing. By uniformly mixing the antibacterial deodorant and a bactericide through the water-based foaming material to become gelatinous, the antibacterial and deodorizing layer is arranged on the leather body according to the size of the leather body. Then, the antibacterial and deodorizing layer is tightly bonded with the leather body by hot pressing, achieving the effects of saving costs, simplifying the manufacturing process, and environmental protection.

The invention relates to treated cellulosic fibers comprising internally dispersed cuprous oxide (Cu.sub.2O) nanoparticles, methods of preparing such treated cellulosic fibers, and uses of such treated cellulosic fibers.

An aqueous disinfectant solution having a stable ionic form of metals like silver, copper, and zinc in combination having significant ability to kill or disabling microorganisms and acts as antifungal as well with an extended useful shelf-life characterized by its noncorrosive nature and possesses better residual efficacy.

A system for handling used packaging film in a food processing facility is provided. The system stores the used film in a refrigerated truck trailer at the food processing facility to prevent rotting, prior to transporting the film to a treatment facility where the film may be recycled.
