The Magnetic Nanomaterial Biofunctions in Cancer Diagnosis and Therapy

Magnetic nanomaterials have recently emerged, playing an increasingly essential role in life science and biomedicine fields, and they exhibited promising potentials in cancer diagnosis and therapy. Also, their use as contrast agents improved various cancer diagnostic imaging sensitivities and accuracy. Magnetic nanomaterials are also exploited as targeted drug carriers to increase the sensitivity and reduce the side effects of chemotherapeutic drugs. Herein, we reviewed the preparation, characterization, and surface modification of various magnetic nanomaterials and their cancer diagnosis and therapy applications.
