Recently, gold and iron nanomaterials have proved their efficiency for cancer therapy. Several kind of nanostructures can treat cancer tumor.In this book, we summarized the new advances of nanomaterials for cancer therapy. For example, photothermal therapy represents a non-invasive therapeutic tool to eradicate cancer tumor with minimum toxic effects. Gold nanomaterials are efficient to passively target and deliver photothermal agents to the cancer tumor. Through surface plasma resonance, gold nanomaterials including nanorods, nanostars, nanoflowers, nanocages and nanoshells exhibited strong...
