We show how two-photon fluorescence signal can be used as an effective detection scheme for trapping particles of any size in comparison to methods using back-scattered light. Development of such a diagnostic scheme allows us a direct observation of trapping a single nanoparticle, which shows new directions to spectroscopy at the single-molecule level in solution.
我们展示了与使用背散射光的方法相比，双光子荧光信号如何能够作为一种有效的检测方案来捕获任何尺寸的粒子。这种诊断方案的开发使我们能够直接观察单个纳米粒子的捕获过程，这为溶液中单分子水平的光谱学研究指明了新的方向。
