Evaluation of immunotherapeutic efficacy.

<p>For PC-3 mice, tumor volumes were significantly smaller for 7F5@Au/Fe3O4 treated animals (p<0.05) compared to those mice with IgG@Au/Fe3O4 control probe (<b>A</b>). No significant difference in tumor volume progression was observed for SMMC-7721 mice following injection of either 7F5@Au/Fe3O4 or IgG@Au/Fe3O4 probes (<b>B</b>).
