Abstract
We tried to evaluate whether blue light in a specific area has an antibacterial effect on S.aureus and S.epidermidis strains,
which are mainly skin flora, or contamination of the environment or equipment. A light source was constructed using
LEDs with wavelengths of 410 nm,450 nm,and 470 nm with a fixed irradiation distance of 15 mm.The irradiation time was
15,30,45,60,and 120 minutes.Under 410nm light source,in all three bacterial species,the PDT-treated samples showed a
significant decrease (p<0.05) in viability. In both bacterial species, the bacterial killing effect was more pronounced
when the irradiation time was increased.
