pubmed:abstractText |
Polypyrrole-Fe3O4 nanospheres were synthesized via an emulsion polymerization method with hyaluronic acid as the surfactant. Hyaluronic acid offers the advantages of biocompatibility, cell adhesive property and the availability of functional groups for attachment of other molecules. The nanospheres were further functionalized with herceptin, and the efficacy of uptake of the functionalized nanospheres by human breast cancer cells was evaluated. It is envisioned that the combination of hyaluronic acid with its cell adhesive property and herceptin would result in high efficacy of internalization of the nanospheres by the cancer cells via a HER-2-mediated endocytosis. Our results showed that this is indeed the case and that the high concentration of herceptin-functionalized magnetic nanospheres in the cancer cells offers great potential in cancer cell targeting and treatment. In addition, the magnetic property of these nanospheres was also critically investigated and the magnetization was found to be affected by the particles' environment. The combination of these cell-targeting magnetic carriers with chemotherapeutic agents will be highly advantageous for the preferential killing of cancer cells in hyperthermia treatment.
