| Research Abstract |
We tried to establish drug delivery systems, targeting cancer cells specifically, using bio-nano-particle composed of liposome and/or proteins as a carrier of anti-cancer reagents. Multivalent design of the carrier to present antibodies or ligands with high affinity to cell surface molecules was found to stimulate endocytosis of the particles. The targeting with the antibodies and ligands made the targeting efficient showing the incubation time of particle with the target cells clearly shorter. Furthermore, the particle escaped from phagocytic macrophages when lipid component was optimized.
