Ask a Scientist – Superhero Edition 4

The video discusses how nanotechnology can mimic biological processes, such as the nano hairs on gecko feet that allow them to stick to surfaces using van der Waals forces. It imagines a superhero, Gecko Man, who uses these principles for disaster relief, crawling into areas to rescue victims and using a nano hair spray to adhere objects together. The video concludes by linking superhero powers to real scientific advancements in nanotechnology, supported by the National Science Foundation.
