Individual surface nanobubbles are visualized with nonintrusive optical interference-enhanced reflection microscopy, demonstrating that their formation is not a consequence of the hitherto used intrusive atomic force microscopy technique. We then use this new and fast technique to demonstrate that surface nanobubbles form in less than a few seconds after ethanol-water exchange, which is the standard procedure for their preparation, and examine how they react to temperature variations.
个体表面纳米气泡可以通过非侵入式的光学干涉增强反射显微镜观察到，这表明它们的形成不是迄今为止使用的侵入式原子力显微镜技术的结果。然后，我们使用这种新的快速技术来证明，在乙醇-水交换后不到几秒钟的时间内就会形成表面纳米气泡，这是它们的标准制备程序，并且还研究了它们如何对温度变化做出反应。
