Disclosed is a method and apparatus for using iodinated polymer as an antimicrobial agent to manage the suppression and disinfection of pathogens.

A method for sterilizing viruses comprises generating a beam having radiating energy therein at a predetermined frequency for generating mechanical eigen-vibrations in a spherical virus to destroy the spherical virus and a predetermined cartesian beam intensity for imparting transverse shear forces to an icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus using beam generation circuitry. A resonance frequency of the spherical virus for inducing the mechanical eigen-vibrations in the spherical virus is determined based upon a size, geometry, and protein material of the spherical virus using a predetermined three-dimensional acoustical model of mechanical vibrations within the spherical virus. The beam generation at the predetermined frequency and the predetermined cartesian beam intensity is controlled using a controller responsive to the determined resonance frequency. The predetermined frequency equals the resonance frequency of the spherical virus. The beam on is radiated a predetermined area to destroy the spherical virus at the predetermined area using radiating circuitry. The mechanical eigen-vibrations at the resonance frequency of the spherical virus determined by the predetermined three-dimensional acoustical model are induced within the spherical virus to destroy the spherical virus responsive to the predetermined frequency. The transverse shear forces are imparted to the icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus.

The disclosure relates to a microbicidal composition with excellent action of limiting a decrease in durability of synthetic adhesives as well as high microbicidal action. The microbicidal composition contains 0.03 to less than 1.0 mass % of peracetic acid, 0.045 to less than 1.5 mass % of hydrogen peroxide, and 0.036 mass % or more of glycine.

A UV light medium can be enhanced to provide specific optical properties that assist in distributing UV light from a UV source to achieve a defined UV light pattern and effective UV disinfection. The properties of the UV light medium can be selected and enhanced by loading the medium with additives, applying a UV blocking pattern, varying the UV light medium material type, thickness, shape, layering, or surface texture. The medium can be any material subject to UV light during a UV treatment or disinfection process. The UV light medium can create a generally uniform UV light pattern that reduces UV hot spots. The UV light medium can diffuse UV light at a target area to enables more robust disinfection with the same or lower UV source intensity.

A method for validating a method for sterilizing an item, making it possible to validate the sterility assurance level achieved with this sterilization method. The method includes carrying out a first step of contaminating a container receiving the item with more than 10.sup.5 living microorganism cells, then carrying out a first sterilization cycle with the chosen method, then opening the container in order to contaminate it again with more than 10.sup.5 living microorganism cells, then carrying out a second sterilization cycle with the same method, and finally checking the sterility of the container after the first sterilization cycle and after the second sterilization cycle. The method is applicable in particular for products and devices intended for health use.
