| Research Abstract |
For successful systemic siRNA delivery towards cancer treatments, this study was aimed to develop the multifunctional polymeric micelles to safely and efficiently deliver siRNA into the cytoplasm of cancerous cells. Eventually, the micelle carrier, which was equipped with a targeting peptide ligand on the surface and stabilized core by 2-iminothiolane-modified polylysine, has achieved the significant growth inhibition of the subcutaneous tumor.
