Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Nanotechnology?Scanning Tunneling Microscope (STM) in 1981 enabled atomic manipulation
2. What is the operational scale?Dimensions ranging from 1 to 100 nanometers, where quantum effects are significant
3. What is the key nanomaterials?Fullerenes, carbon nanotubes, quantum dots, nanoparticles
4. Why can tiny materials behave differently than big ones?At that tiny size, quantum mechanical effects and a huge surface area compared to volume make materials act differently, like turning insulators into conductors or changing how they look.
5. How did scientists first see and move atoms?Scientists first could see and move single atoms with a device called a scanning tunneling microscope, invented in 1981 by Gerd Binnig and Heinrich Rohrer.

Quantum Dots: Semiconductor nanocrystals whose optical and electronic properties depend on their size and shape.
Self-Assembly: The spontaneous organization of molecules or nanoparticles into ordered structures.
Nanomedicine: The application of nanotechnology to healthcare, including diagnostics, drug delivery, and regenerative medicine.
