Abstract
A device for generating singlet oxygen is provided. The device has elongated posts extending from a surface, the lateral sides of which have particles with a sensitizer that converts triplet oxygen to single oxygen upon exposure to light. An optical fiber conveys light to the sensitizer and a gas supply tube conveys oxygen to the sensitizer. The device is configured to keep the sensitizer from contacting external fluids, such as saliva.
