The Effect of Violet Device Dosed Ultra Violet-C Light (UV-C) Exposure on Healthy Hand Skin

The Effect of Violet Device Dosed UV-C Exposure on Healthy Hand Skin

• Status: Active Not Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 30 (estimated)
• Sponsor: University of Michigan · Academic / Other
• Sex: All
• Age: 18 Years – 55 Years
• Healthy volunteers: Accepted

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.

• Healthy Volunteers

Interventions

Type	Name	Description
DEVICE	Ultraviolet Light (UV-B)	This control group will receive a UV-B exposure as a positive control. Participants will have punch biopsies after exposure.
DEVICE	Ultraviolet lights (UV-C)	Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will choose, based on availability, to be in groups that deliver 1 cycle, 10 cycles, 15 cycles or 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.
