Abstract: A method of fixating a tissue sample including: treating the tissue sample with a nano-tissue fixative solution to form a fixated tissue sample. A composition of nucleic acids in the fixated tissue sample is not altered. The nano-tissue fixative solution includes acetic acid, at least one alcohol, chloroform, titanium dioxide nanoparticles, zinc oxide nanoparticles, and silver nanoparticles.

Abstract: A health care and/or entertainment device protective film may be configured to contact human skin, e.g., to limit the transmission of infection by bacteria, fungi, protozoa, prions, and/or viruses. The film may be formed as a nanocomposite film including at least 75 wt. %, relative to total organic matrix weight, of polyethylene, silver particles, and TiO2 particles, wherein the silver particles and TiO2 particles are distributed within and/or on an outer surface of the polyethylene, wherein the silver particles have a size of 1 to 1,000 nm, and wherein the TiO2 particles have a size of 1 to 50 nm. Such films may be applied to health care and/or entertainment devices, including virtual reality googles.

Abstract: A filter may remove PM2.5 and/or other airborne pollutants, which filter has fibers of an average diameter of no more than 500 nm, the fibers of at least 90 wt. % polyacrylonitrile, relative to all fibers in the filter; and a catalyst of at least 90 wt. % TiO2, relative to all catalytic metals in the filter, dispersed onto the fibers. The fibers need not be charged. The TiO2 may be condensed or precipitated onto the fibers out of a liquid containing the TiO2 and the fibers by simple methods. The catalyst may be activated by UV irradiation to decompose particulate matter having an average particle size of 2.5 ?m or less, i.e., PM2.5, and/or other airborne pollutants from air. Such filters may be implemented around areas of vehicle traffic, e.g., as elements of traffic lights, and may be used to controllably purify polluted air.

Abstract: A method of reducing contaminants in air, including applying titanium dioxide-containing growth media to at least one of a Myrtus communis plant root, stem, and leaf, and growing the plant. The growth media is a liquid growth media, a gel growth media, or both. The plant is then exposed to contaminant-containing air. The contaminant is CO2, SO2, formaldehyde, CO, benzene, toluene, xylene, ethyl benzene, or a combination thereof. The contaminant concentration in the air is reduced relative to a contaminant concentration in the air prior to the exposing. A plant portion having a portion of a Myrtus communis plant comprising an infused titanium dioxide is also described. The portion is at least one of a root, stem, or leaf. In a closed environment, the plant portion reduces the concentration of a contaminant in the air in the closed environment.
