Abstract
In this study, we focused on using the properties of Psoralen to create antibacterial sheets. Most
antibacterial sheets contain alcohol. Also, alcohol can cause inflammation to the skin. Making
antibacterial sheets which are not harmful to the human body help alleviate these problems.
Antibacterial effect was the most found under the condition when concentration of Psoralen was 1/100
and irradiation time was 10 minutes. Also, Psoralen absorbed UV light and combined with DNA extract.
It was found that antibacterial sheets can be made by using Psoralen.

Keywords: Psoralen, antibacterial sheet, UV light, DNA extract
