Prospects for Photodynamic Therapy in Dentistry
Photodynamic therapy (PDT) involves the use of a photosensitizer that is activated by illumination in the presence of oxygen. The exposure of the photosensitizer to light results in the formation of toxic oxygen species, thereby causing localized photodamage and cell death. Applications of the technique in dentistry may include photodynamic diagnosis of malignant transformation of oral lesions, treatment of premalignant and malignant oral lesions, and chemotherapy (PACT) of bacterial and fungal...

Light Creates Tiny Patterns
The old trick, practiced by schoolboys everywhere, of concentrating a beam of sunlight through a magnifying lens to ignite paper -- or an unfortunate ant -- has been given a new twist. By using a microscopic plastic bead in place of the lens and...
