| Research Abstract |
We developed an Indocyanine-green conjugated micelles (Lac-ICG) as a novel DDS (drug delivery system)-type photosensitizer that can selectively accumulate in cancer tissues.We examined the usefulness of Lac-ICG in photodynamic diagnosis (PDD) and photodynamic therapy (PDT). 48-72h after administration of Lac-ICG into tumor-bearing mouse models, tumors were clearly distinguished from the surrounded normal tissue on the basis of the Lac-ICG fluorescence. In addition, PDT using Lac-ICG exerted excellent anti-tumor effects.
