摘要

在本研究中，研究了球形、核壳和棒状锇纳米粒子的热等离子体特性。为了研究这些特性，采用三维有限元方法模拟了同步辐射发射作为光束能量的函数与锇纳米粒子的相互作用。首先计算了吸收和消光截面。然后，通过求解热方程，计算了同步辐射发射引起的温度升高与光束能量吸收的关系。所获得的结果表明，锇纳米棒是一种更合适的选择，可用于光热人体癌细胞、组织和肿瘤的治疗方法。锇纳米粒子的50000x图像

Drug delivery systems (DDSs) of osmium nanoparticles on human gum cancer cells, tissues and tumors treatment under synchrotron radiation

In the current study, thermoplasmonic characteristics of Osmium nanoparticles with spherical, core-shell and rod shapes are investigated. In order to investigate these characteristics, interaction of synchrotron radiation emission as a function of the beam energy and Osmium nanoparticles were simulated using 3D finite element method. Firstly, absorption and extinction cross sections were calculated. Then, increases in temperature due to synchrotron radiation emission as a function of the beam energy absorption were calculated in Osmium nanoparticles by solving heat equation. The obtained results show that Osmium nanorods are more appropriate option for using in optothermal human cancer cells, tissues and tumors treatment method. image of Osmium nanoparticles with 50000x
