Nanocarriers for cancer therapy have been extensively studied, but there is still some research that must be addressed in order to achieve their safe application. In this field, hyperthermia thermal treatments mediated by the use of responsive nanomaterials are not different, and researchers have carried out many attempts to overcome their drawbacks due to the valuable potential of these techniques. Here, an overview is presented of nanodevices based on magnetic‐ and photoresponsive nanocrystals that respond to magnetic fields and/or near‐infrared stimuli for cancer therapies. Special attention is given to the synergic effect that can be achieved with nanoscale heating in combination with chemotherapy through drug‐delivery devices to effectively kill cancer cells. In this way, the nanoparticles act as heating sources or “hot spots,” which can trigger cellular responses in the absence of a global temperature rise, making the tumor cells more sensitive to chemotherapeutics. The fabrication of optical and magnetic drug‐delivery devices, the heating mechanisms, and their applications in tumor treatment are also summarized.
