A method of inactivating harmful microorganisms of a filtration medium including pathogenic bacteria and viruses is disclosed which includes placing a predetermined quantity of a hybridized fluorescent silk on to a filtration medium, applying light for a predetermined amount of time to the placed quantity of the hybridized fluorescent silk, and passing a fluid through the medium, wherein the fluid is one of substantially air or substantially water,

wherein the hybridized fluorescent silk is one of KillerRed, SuperNova, KillerOrange, Dronpa, TurboGFP, mCherry, or any combination thereof.

A system and method according to various embodiments combines three separate technologies to form a unique lighting system with enhanced antimicrobial properties and air cleaning capabilities. The combination of the three technologies also produces a lighting system that extends the required maintenance period for lighting fixtures. The first technology is based on anatase type TiO.sub.2. The second and third technologies are based on the use of micro-sized surface structures to generate light scattering effects and, at the same time, reduce bacterial colonization and inhibit bacterial migration even during the absence of light or in dark environments.

The invention relates to a medical apparatus for extracorporeal blood treatment, comprising an antimicrobial surface coating, wherein the antimicrobial surface coating is a powder coating. It further relates to a method for controlling microbes and microorganisms on a surface of a medical apparatus, wherein a powder coating contains components, in particular additives, with an antimicrobial effect.

A sanitizing photocatalytic reactor suitable for air liquid or liquid fluids includes a reaction region containing a photocatalyst selected from nanotechnological materials of natural light photocatalyst type, which is supported on an inert support or mixed with a plastic material, and an illumination region having white color LED lights, the reaction region further having one or more channels through which the fluids to be sanitized flow.

A shoe management apparatus including a cabinet including an inner space for storing shoes, an exhaust port disposed at a rear surface of the inner space and discharging air into the inner space, and a front discharge port disposed at an upper surface of the cabinet and discharging air from the inner space to outside of the shoe management apparatus.

A shoe management apparatus including a cabinet defining an inner space for storing shoes, an exhaust port disposed at a rear surface of the inner space and discharging air into the inner space, and a circulation filter disposed on an inner wall of the cabinet and for filtering air within the inner space of the cabinet, the circulation filter including an upper portion including a first opening and a lower portion including a second opening, the lower portion being disposed below the upper portion.

Provided are methods of reducing and killing bacteria and fungi, and photodynamic treatment methods and sterilization methods using the methods of reducing and killing bacteria and fungi. The method of reducing and killing bacteria and fungi includes bringing a composition including a Ligularia fischeri extract or a fraction thereof as an active ingredient into contact with cells or tissues of a subject and irradiating cells or tissues of a subject in contact with the composition with an absorbable wavelength of excitation light.

A dehaze and bacteriostatic film includes a substrate material layer and a composite surface plasmon layer formed on the substrate material layer. The composite surface plasmon layer includes a particle stacked film layer and a particle suspension layer located on the substrate material layer, and the particle stacked film layer and the particle suspension layer jointly generate a composite surface plasmon wave. Accordingly, the composite surface plasmon wave is excited by visible light, so that different types of surface plasmon waves generated by the structures resonate and multiply with each other. The different surface plasmon waves add up to generate electromagnetic field intensity capable of dissociating spatial materials at a certain distance, such as water vapor to be partially ionized which is rich in hydroxide ions with effects of dehazing and inhibiting growth of bacteria.

A point-of-use (POU) water filtration device has a container. A plurality of channels is formed within the container, water entering the container flowing through the plurality of channels. A plurality of Ultraviolet (UV) Light Emitting Diodes (LEDs) is provided. Each of the plurality of UV LEDs illuminating UV light down an associated channel of the plurality of channels.

This document describes self-cleaning devices. In one aspect, a self-cleaning device includes a fabric having a surface covered with a photocatalyst, one or more light sources embedded in the fabric, and a triggering mechanism that activates a cleaning cycle by activating the one or more light sources. The triggering mechanism can include a pressure sensor. The triggering mechanism can be configured to activate the cleaning cycle in response to detecting a decrease in pressure being applied to the pressure sensor.
