| Outline of Final Research Achievements |
Infrared laser irradiation after intravenous administration of indocyanine green increases vascular permeability at skin and dermo-muscular layer of rats. Subsequently induced intravenous gold nano-rods and infrared laser irradiation effectively injure skin and subcutaneous tissue. This indicates that GNRs would be highly concentrated in the tissue by EPR effect. The effect exerts intensely at superficial layer of the skin and is unaffected by blood flow. Thus, this method could be available for drug delivery system on tissues which have poor blood flow.
