Gold nanoparticles in radiofrequency (RF) fields have been observed to heat. There is some debate over the mechanism of heating. Au₂₅(SR)₁₈ in RF is studied for the mechanistic insights obtainable from precise synthetic control over exact charge, size, and spin for this nanoparticle. An electrophoretic mechanism can adequately account for the observed heat. This study adds a new level of understanding to gold particle heating experiments, allowing for the first time a conclusive connection between theoretical and experimentally observed heating rates.

Au25(SR)18 射频场加热的电泳机理

已观察到射频 (RF) 场中的金纳米颗粒会发热。关于加热机制存在一些争论。对 RF 中的 Au ₂₅ (SR) ₁₈进行了研究，以获得通过对该纳米粒子的精确电荷、尺寸和自旋进行精确合成控制而获得的机械见解。电泳机制可以充分解释观察到的热量。这项研究为金颗粒加热实验增加了新的理解水平，首次在理论和实验观察到的加热速率之间建立了决定性的联系。
