Abstract

The heating potential of Mg nanoparticles (NPs) subjected to near infrared (NIR) radiation has been investigated as an agent for mild hyperthermia treatment (42-43°C). The surface plasmonic resonance of different configurations of Mg nanospheres was calculated via the use of the discrete dipole approximation (DDA) method and compared with a case of a single Mg nanosphere. To investigate the impact of the optical properties on heat generation efficiency of irradiated aqueous solutions with different Mg NPs structures, a computational model for both radiative and transient heat transfer was developed. Numerical results are compared with measured temperatures to provide an understanding of the relationship between the clustering effect and irradiation efficiency of Mg NPs. It was found that the aggregation of Mg 80 nm diameter nanospheres improved plasmonic absorption efficiency at the NIR wavelength. Given the biological safety, as well as increased heating characteristics, controlled aggregations of Mg NPs can be beneficial in tumour therapy.
