Abstract

The generation and manipulation of microbubbles on surfaces have been much more ubiquitous than those in the bulk liquid. In this paper, we report the generation and trapping of microbubbles at the laser boundary in the bulk of water. In a plasmonic suspension, the light intensity-induced temperature gradient leads to a Marangoni flow that can trap the microbubble. The trapped microbubble can be directed by the light to move in water at speeds at least as high as 0.9 mm/s. These findings can potentially extend the boundary of bubble applications from surfaces toward the bulk of the liquid and open intriguing possibilities in fields like drug delivery and nano/microfabrication, among others.

体溶液中激光诱导的微泡捕获。

表面微泡的产生和操纵比散装液体中的微泡更为普遍。在本文中，我们报道了在激光边界处微气泡的产生和捕获。在等离子体悬浮液中，光强引起的温度梯度导致马兰戈尼流，可以捕获微泡。被捕获的微泡可以在光的引导下以至少高达0.9毫米/秒的速度在水中移动。这些发现可能会将气泡的应用范围从表面扩展到大部分液体，并在药物输送和纳米/微制造等领域开辟有趣的可能性。
