Have you ever played with a toy train set? Imagine that the train tracks are like a wire that can carry electricity. Now, let's make the train tracks very small, so small that we can't see them with our eyes. We call these tiny tracks "molecular wires."
Just like regular train tracks, molecular wires allow electricity to flow through them. The difference is that molecular wires are made of tiny molecules that are designed to conduct electricity. These molecules are like little messengers that carry electrical energy between different parts of a device.
Scientists use molecular wires to build very small electronic devices, like computer chips. These devices are so tiny that they can fit inside your phone or your watch. By using molecular wires, scientists can make these devices even smaller and more efficient.
So, next time you see a train set, imagine how those big tracks could be made tiny like molecular wires and help power all sorts of electronic devices.
