Gecko Feet

Gecko feet are specialized structures that allow these animals to adhere to and move across smooth surfaces. Their feet are covered with tiny hair-like structures called setae, which branch into even smaller tips called spatulae. These spatulae increase the surface area in contact with surfaces, exploiting molecular forces known as van der Waals forces. These weak but collectively strong forces enable geckos to stick, climb, and maneuver seamlessly without adhesives or glue. The design is a remarkable example of natural nanotechnology, balancing adhesion and ease of movement.
