A system for the treatment of microorganisms includes: a textile web having optical fibers in warp and/or weft woven with binding threads in warp and/or weft, each of the optical fibers having invasive alterations along the fiber and allowing the emission of light propagating in the fiber at these alterations; a light source arranged opposite one or both free ends of the optical fibers. The textile web includes metallic warp and/or weft threads woven with the binding threads, the metallic threads being based on a metal having a negative effect on the growth of microorganisms. The light source generates a light beam having at least one wavelength in the visible or ultraviolet spectrum.

An air decontamination device (100) comprising: an input unit (102); an output unit (103); and a decontamination unit (104) coupled at a first end (122) to the input unit (102) and coupled at a second end (124) to the output unit (103). The decontamination unit (104) comprises: pairs of conducting plates (108), where one conducting plate of each pair is for being positively charged and the other conducting plate of each pair is for being negatively charged. The positively charged plate and negatively charged plate are separated to form an airflow path (212) and a 3D material (110) that is capable of being potentiated by static electric field is coupled to each side of conducting plate (108). When the static electric filed is applied, the surface moieties of the 3D material (110) are realigned to a direction of the static electric field to potentiate the antimicrobial activity of the 3D material (110) for destroying the microbes present in the received air.

An anti-microbial metal coating may be applied to filter membranes for use in actively depressing microbial viability in filtration applications. The anti-microbial metal coating may be applied to substrates that are considered to be sensitive to damage by conventional metal coating techniques or resistant to metal bonding. The coating may be applied from a salt absorbed to the substrate in solution, converted to a reducible form with a conversion agent, and reduced to active metal format through a low temperature plasma treatment.
