Nanoparticle films organized by soap bubbles

Soap bubbles are seemingly simple "fragile" objects that are familiar to us. However, many industrial processes require in-depth knowledge of these objects, which are much more organized than they appear. We will show that after the water has drained away, the walls of the bubbles have highly ordered structures whose strong potential for self-organization can be used to confine nanoparticles of various kinds, thus paving the way for new applications.
