Abstract
Methods and apparatus for sanitizing and/or sterilizing a material, including placing a material to be sanitized and/or sterilized into a reaction chamber, and simultaneously exposing the material to be sanitized and/or sterilized to an ultraviolet light selected to decrease a number of living or viable microorganisms in or on the material, and to a magnetic field having a field strength selected to prolong a lifetime of a free radical entity generated by the ultraviolet light exposure for a time sufficient to prolong the lifetime of the free radical entity.
Claims12
A method of sanitization, comprising:
- placing a material to be sanitized into a reaction chamber;
- simultaneously exposing the material to be sanitized to an ultraviolet light selected to decrease a number of living or viable microorganisms in or on the material, and to a magnetic field having a field strength selected to prolong a lifetime of a free radical entity generated by the ultraviolet light exposure for a time sufficient to prolong the lifetime of the free radical entity;
- removing the sanitized material from the reaction chamber.
An apparatus for sanitizing a material, comprising:
- a reaction chamber for receiving the material to be sanitized;
- wherein the reaction chamber is configured to irradiate the material to be sanitized with an ultraviolet light selected to decrease a number of living or viable microorganisms in or on the material;
- the reaction chamber is configured to expose the material to be sanitized to a magnetic field having a field strength selected to prolong a lifetime of a free radical entity generated by the ultraviolet light irradiation for a time sufficient to prolong the lifetime of the free radical entity;
- and
- the irradiation of the material with the ultraviolet light and the exposure of the material to the magnetic field is substantially simultaneous.
