today’s cyclodextrin:
is certainly a fancy application that has been around for years, yet its commercial application is still waiting around the corner: self-healing systems. This field is pioneered by the group of Akira Harada at Toyota Motor Corporation (earlier Osaka University), by now, there are several other groups working on creating such networks. In the first article, you can find some videos and animations to understand how the concept works.
The main uses proposed so far have been in the automotive industry as car paint or surface cover, similar to cellphones.
