Outline of Final Research Achievements |
Nanotubes (NTs) composed of DNA and polyethyleneimine were synthesized by alternating layer-by-layer assembly method using nanoporous polycarbonate membrane as a template. Doxorubicin (Dox), a DNA intercalating anticancer drug, can be loaded into the DNA layers of the NTs with high density. Dox-loaded DNA NTs were incorporated into the cancer cells and clearly showed anticancer activity. This activity was drug dose-dependent and slightly higher than that of Dox solution. Moreover, DNA NTs, prepared by using a plasmid DNA vector, successfully delivered the GFP (green fluorescent protein) gene into mammalian cells.
