本文首次用倏逝波激光诱导成核的方法研究了玻璃-溶液界面上的晶体成核。在过饱和氯化钾（KCl）水溶液中诱导成核。相互作用体积估计为<2 nL，位于界面的约100 nm内。的成核事件的功率依赖性的测量表明，激光功率阈值，这是大约3倍高于实验中的散装溶液中的成核事件的平均数量高于阈值是类似的散装。用疏水性聚二甲基硅氧烷基涂层处理的表面在涂覆区域上没有显示成核。这种方法提供的定位对于成核机制的研究或二维晶核的图案化具有显着的潜在好处。
Crystal nucleation at a glass–solution interface has been demonstrated by evanescent-wave laser-induced nucleation for the first time. Nucleation was induced in supersaturated aqueous potassium chloride (KCl) solutions. The interaction volume was estimated to be <2 nL, localized within approximately 100 nm of the interface. Measurements of the power dependence of nucleation events showed a laser power threshold that was approximately 3 times higher than that in experiments in bulk solution; the average number of nucleation events above threshold was similar to that in bulk. Surfaces treated with a hydrophobic polydimethylsiloxane-based coating showed no nucleation over the coated regions. The localization offered by this method has significant potential benefit for studies of the nucleation mechanism or for patterning of crystal nuclei in two dimensions.
