The Effect of Violet Device Dosed Ultra Violet-C Light (UV-C) Exposure on Healthy Hand Skin
Sponsor: University of Michigan
Summary
The purpose of this trial is to determine the safety of ultraviolet light (UV-C) irradiation as a method to sanitize hands instead of chemical-based sanitizers. Eligible participants will be enrolled and receive treatment with the Violet UV-C device or UV-B. Punch biopsies will be performed following UV exposure to quantify any changes in cellular and molecular properties of the tissue.

Ultraviolet Light (UV-B)
This control group will receive a UV-B exposure as a positive control. Participants will have punch biopsies after exposure.
Ultraviolet lights (UV-C) - 1 cycle
Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will be exposed to 1 cycle of the Violet. The subject will be exposed for no more than 5 minutes and 20 seconds in total. Participants will have punch biopsies after exposure.
Ultraviolet lights (UV-C) - 10 cycles
Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will be exposed to 10 cycles of the Violet. The subject will be exposed for no more than 5 minutes and 20 seconds in total. Participants will have punch biopsies after exposure.
Ultraviolet lights (UV-C) - 15 cycles
Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will be exposed to 15 cycles of the Violet. The subject will be exposed for no more than 5 minutes and 20 seconds in total. Participants will have punch biopsies after exposure.
Ultraviolet lights (UV-C) - 25 cycles
Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will be exposed to 25 cycles of the Violet. The subject will be exposed for no more than 5 minutes and 20 seconds in total. Participants will have punch biopsies after exposure.
