Numerical study of optical and thermal response of gold and silver coated copper nanostructures for hyperthermia

Original language description

The optical and thermal properties of nanoparticles have attracted much interest due to their extinction effectiveness in industries like electronics, medical devices, photonics, materials sciences, drug delivery, hyperthermia, etc. In this work, the optical response of eight different geometrical nanostructures, namely Solid-CuNS, Au–Ag-coated-Solid-CuNS, Hollow-CuNS, Au–Ag-coated-Hollow-CuNS, Solid-CuNR, Au–Ag-coated-Solid-CuNR, Hollow-CuNR, and Au–Ag-coated-Hollow-CuNR, were studied for hyperthermia. Finite element analysis was performed in COMSOL Multiphysics to simulate the optical and thermal responses of the nanostructures. The size range of nanostructures was selected differently based on the hyperthermia condition to attain a temperature between 42 °C and 46 °C. An appropriate temperature distribution of 43.8 °C was achieved in the 500 nm liver domain using an Au–Ag-coated-Solid-CuNS with Dsphere = 20 nm. The minimum thermal response was 42.1 °C for both Solid-CuNS and Solid-CuNR when Dsphere was 35 nm and Lcylinder was 35 nm. The highest electric field distribution of 11.2 V/m in the surrounding area was seen for Au–Ag-coated-Solid-CuNR, with an extinction resonance peak at 475 nm. On the other hand, the Au–Ag-coated-Solid-CuNS showed the least electric field distribution of 2.22 V/m with a corresponding resonance peak of 480 nm when Dsphere was 15 nm.
