近年来，人们对利用金属纳米结构在纳米尺度上控制温度的兴趣日益浓厚。在等离子体共振的光照下，金属纳米粒子具有增强的光吸收特性，使其成为理想的纳米热源，并且可以使用光进行远程控制。这种强大且灵活的光热方案是热等离子体学的基础。在此，对这一新兴且快速发展的领域的最新进展进行了综述。首先，描述了在连续和脉冲光照下金属纳米粒子中热量产生的物理原理。第二部分致力于介绍为进一步理解和设计纳米尺度上的等离子体辅助加热过程而开发的数值和实验方法。最后，综述了一些基于金纳米粒子产生的热量的最新应用，即光热癌症治疗、纳米手术、药物递送、光热成像、蛋白质追踪、光声成像、纳米化学和光流体学。
Recent years have seen a growing interest in using metal nanostructures to control temperature on the nanoscale. Under illumination at its plasmonic resonance, a metal nanoparticle features enhanced light absorption, turning it into an ideal nano-source of heat, remotely controllable using light. Such a powerful and flexible photothermal scheme is the basis of thermo-plasmonics. Here, the recent progress of this emerging and fast-growing field is reviewed. First, the physics of heat generation in metal nanoparticles is described, under both continuous and pulsed illumination. The second part is dedicated to numerical and experimental methods that have been developed to further understand and engineer plasmonic-assisted heating processes on the nanoscale. Finally, some of the most recent applications based on the heat generated by gold nanoparticles are surveyed, namely photothermal cancer therapy, nano-surgery, drug delivery, photothermal imaging, protein tracking, photoacoustic imaging, nano-chemistry and optofluidics.
