Gold nanostars are theoretically studied as efficient thermal heaters at their corresponding localized surface-plasmon resonances (LSPRs). Numerical calculations are performed through the 3D Green's Theorem method to obtain the absorption and scattering cross sections for Au nanoparticles with star-like shape of varying symmetry and tip number. Their unique thermoplasmonic properties, with regard to their (red-shifted) LSPR wavelentgh, (∼ 30-fold increase) steady-state temperature, and scattering/absorption cross section ratios, make them specially suitable for optical heating and in turn for cancer thermal therapy.
从理论上研究了金纳米星作为其相应局域表面等离子体共振（LSPR）处的高效热加热器。通过三维格林定理方法进行数值计算，以获得具有不同对称性和尖端数量的星形金纳米粒子的吸收和散射截面。它们独特的热等离子体特性，包括其（红移的）LSPR波长、（约30倍增加）稳态温度以及散射/吸收截面比，使其特别适合于光热加热，进而适用于癌症热疗。
