Noble Metal Structures: Photo-Thermal Properties Enhancement

Theoretically speaking, within the track of photothermal therapy, heat impacts to cancer cells localization is overspreading strategy for confronting cancer. It helps in decreasing the side impacts on cells close to tumors, enhances the quality of life of affected people, and by and large, and consequently, the hyperthermia impact is upgraded. The nanoparticles optical features are based on their form and size. The main objective of our work is a trial to upgrade the photo-thermal features some noble metal nanostructures by enhancing the absorption characteristics. This is accomplished by utilizing unused shapes in addition to some modern geometrical forms of nanoparticles self-similar clusters. The significance is of this work is its use in treating tumors, through distributed heating, especially caused by cancer and destroying the injured cells, while keeping the other cells safe. The nano-rod single element is used, achieving absorption of − 31.8 dB at 613.5 THz. Also, the proposed nano-sphere shape results in an optimum performance that exceeds literature reported results, achieving absorption of - 42.5 dB at 1035 THz.
