Atomic-force microscopy

Atomic-force microscopy is like a tiny robot that helps us see things that are too small to see with our eyes. This robot has a really small tip at the end of its arm that can feel and touch things like a tiny finger. When the robot moves around and touches things, it creates a picture that helps us understand what things look like on a very, very small scale.

You can think of it like a game where you're blindfolded and you have to figure out what an object is just by touching it. The robot is like your hand, and the tip at the end of the arm is like your finger. And instead of feeling an object, the robot feels the atoms and molecules that make it up.

Scientists use atomic-force microscopy to study things that are too small for us to see with our eyes, like cells and even individual atoms. With this tool, they can learn more about how things are put together and how they behave, and it can help them make new discoveries about the world around us.
