| Outline of Final Research Achievements |
Recently, clinical application of carbon nanotube (CNTs) has been proposed as drug delivery agents. Polyethylene glycol and fluorescent dye, Cy5, was bound to CNTs to synthesize Cy5-PEG-CNT towards application of CNTs as DDS carrier. After intravenous administration, Cy5-PEG-CNT was not metabolized, nor degraded in rat body, and was excreted immediately into urine and bile. In order to obtain Cy5-PEG-CNT with uniform physicochemical properties, classification of length with membrane filter, or application of CNTs synthesized by enhanced Direct Injective Pyrolytic Synthesis method were attempted, but Cy5-PEG-CNT with sufficient amount of Cy5 was not obtained. On the other hand, exposure of CNTs down-regulated several types of CYP molecular species in rat and human liver derived cells.
