Abstract
The development of the multi-functional nanostructures has recently been of particular interest in therapeutic research for various diseases including atherosclerosis, cancer, etc. Indeed, the use of multi-responsive nanostructures that can remotely be activated by different stimuli is a promising strategy to combine the advantages of standalone methods and overcome their intrinsic drawbacks. In this regard, thermal treatment using heat-generating magnetic nanostructures that can remotely respond to a wide range of electromagnetic stimuli is of especial importance, mainly applied through magnetic hyperthermia therapy (MHT) and photothermal therapy (PTT) modalities. In this work, magnetite (Fe3O4) nanorods (MNRs) were synthesized using a one-pot solvothermal process. Adjusting the amount of hexadecylamine capping ligand and the filling percentage of the autoclave, uniformed-sized MNRs of 4·46nm in diameter and 31·09nm in length were prepared and investigated in terms of their heat-generating ability for application in the MHT and PTT. The experimental results show the good heat-generating ability of the MNRs in both modalities with the maximum absorption rate (SAR) values of 228.51 W/g (MHT) and 56.59 W/g (PTT).
