Fe3O4 nanoparticles (NPs) have been widely used in biomedicine due to their unique magnetism, biocompatibility, and biodegradability. Magnetic hyperthermia of Fe3O4 NPs for cancer treatment has attracted more attention. However, it could interfere with magnetic field-sensitive devices of patients, such as pacemakers. Therefore, it is necessary to find a new method for clinical therapy. In this study, the superparamagnetic Fe3O4 NPs were fabricated. Visible-near-infrared absorption spectra indicated that the Fe3O4 NPs have near-infrared absorption. The influences of Fe3O4 NP concentrations, power density, and wavelength of near-infrared laser irradiation on the photothermal performance of Fe3O4 NPs were investigated. The results revealed that high concentrations, large power density, and short irradiation wavelength could improve the photothermal performance of Fe3O4 NPs. The temperature variation and the absorption intensity simultaneously determined the photothermal transduction efficiency of Fe3O4 NPs. The application of the photothermal performance of Fe3O4 NPs would provide a new opportunity for clinic cancer treatment.

The Matrix

A robust photothermal healing method relies on the NIR photothermal effect of Fe3O4 NPs in the matrix. It allows thermoplastic materials and coatings to be repaired in air, and the coatings to be repaired more effectively underwater.
