| Outline of Final Research Achievements |
In this study, we tried to develop DDS carriers, which can sense pH change and move autonomously in tumor environment. In the first year, we found that detailed consideration of conditions was required for preparation of bacterial ghost, and succeeded in isolation of flagellar. In the second year, we succeeded in the preparation of bacterial ghost. In addition, we confirmed the existence of flagellar filament component protein, FliC, in the ghost. Based on these results, we concluded that we succeeded in the preparation method of bacterial ghost. Furthermore, we developed the nanoparticles, of which surface was modified with tumor penetrable functional peptide AT1002 and polyethyleneglycol, and succeeded in observation of penetration of the nanoparticles into cancer cell spheroids.
