The aerogel was created by a team at the Helsinki University of Technology, and contains tiny fibers known as nano-fibrils, derived from the cellulose in plants. The presence of the fibers allows the aerogel to float using the same principles employed by the water strider’s long, skinny feet. Those feet are covered in tiny hairs that trap air, and that help spread the insect’s weight across the water, keeping it from breaking the surface tension.
Once commercialized, the aerogel could find use in things such as miniature military robots, environmental pollution sensors, children’s water toys or beach floats. It is also able to absorb large amounts of oil, which could make it well-suited to use in cleaning up oil spills.
