Light-driven nanomotors have attracted much attention due to their potential applications. The movement of conventional nanomotors typically occurs in the solution phase, which limits their application fields. Utilizing visible light to drive nanomotors at the solid-liquid interface represents a grand challenge due to the large friction force between the nanomotor and the solid surface. Based on the attractive plasmon resonance of Au nanocrystals, for the first time, plasmon-enhanced Au nanocrystal-based nanomotors moving at the silicon-aqueous solution interface have been developed. Such nanomotors move with a clear trace engraved on the Si surface, representing an excellent and exceptional self-traced nanomotor system. In addition, the nanomotor trace on the Si surface also provides a unique and promising approach to the fabrication of nanoscale Si patterns, which is central to many applications, including microelectronics, sensing, information storage, and optoelectronics.
光驱动纳米马达因其潜在应用而备受关注。传统纳米马达的运动通常发生在溶液相中，这限制了它们的应用领域。由于纳米马达与固体表面之间存在较大摩擦力，利用可见光在固液界面驱动纳米马达是一项巨大挑战。基于金纳米晶体的吸引等离子体共振，首次开发出了在硅-水溶液界面移动的等离子体增强金纳米晶体基纳米马达。此类纳米马达在硅表面留下清晰的轨迹，代表了一种出色且独特的自追踪纳米马达系统。此外，硅表面的纳米马达轨迹还为纳米级硅图案的制造提供了一种独特且有前景的方法，这对于包括微电子、传感、信息存储和光电子学在内的许多应用至关重要。
