Ever wanted to put on that Spiderman suit and climb up walls? Well, scientists are exploring the possibilities by studying geckos rather than spiders. This BBC article explains recent research into the gecko’s incredible ability to climb.
“The underside of a gecko’s foot looks like a tyre tread and is covered in millions of microscopic hairs. Each hair splits into hundreds of tips just 200 billionths of a metre wide.
The secret of this lizard’s adhesion turns out to be the relatively weak intermolecular forces that draw materials together any time they get close.”
“Prof Autumn, from Lewis & Clark College in Oregon, added: “What is special about it is that it is controllable. And its controllability is based on geometry and physics, not chemistry.””
So, donning our spiderman suits and scaling huge buildings might eventually become a reality.
