Abstract

The present disclosure describes a chamber with an interior UV reflective surface, and a light source emitting an ultraviolet light that is used to kill microorganisms on one or more surfaces of an object, thereby sanitizing the object.

or

d) the reflective material is a surface coated with a UV reflective paint.

4. The chamber of claim 1, wherein

a) the one or more supports comprise quartz;

or

b) the one or more supports comprise a pocket in which the object can be placed.

5. The chamber of claim 1, wherein the emitted ultraviolet light is from about 100 nm to about 300 nm, from about 220 nm to about 280 nm, from about 240 nm to about 280 nm, from about 220 nm to about 320 nm, or from about 250 to 270 nm, or about 254 nm or about 265 nm.

6. A method of sanitizing an object or the surface of an object, comprising:
