Inspired by biological motors, we propose a guiding principle for selectively separating nanoparticles (NPs) by efficiently using the light-induced force (LIF) and thermal fluctuations. We demonstrate the possibility of transporting metallic NPs of different sizes with a size-selection accuracy of less than 10 nm even at room temperature by designing asymmetric spatiotemporal light fields. This technique will lead to unconventional nanoextraction processes based on light and fluctuations.
受生物马达的启发，我们提出了一个指导原则，通过有效地利用光致力（LIF）和热涨落来选择性地分离纳米粒子（NPs）。我们通过设计非对称时空光场，证明了即使在室温下，也可以用小于 10nm 的尺寸选择精度来传输不同尺寸的金属 NPs。这项技术将基于光和涨落产生非常规的纳米提取过程。
