Inside The World's Most Powerful New Microscopes

What is the approximate smallest size a traditional visible-light microscope can clearly show?

• 200 nanometers

• 20 nanometers

• 2 nanometers

• 75 nanometers

What special molecules are used in STED and Single Molecule Imaging techniques to help scientists see tiny details?

• Electrons

• Fluorophores

• Proteins

• DNA strands

What is a major benefit of using X-rays for microscopy, especially when studying living things?

• It makes samples glow brightly.

• It allows samples to be studied while alive.

• It uses less light than traditional microscopes.

• It is much cheaper to operate.

Why can scientists get an image of a sample using powerful X-rays before the sample is destroyed?

• The X-rays are very weak and don't cause damage.

• The sample is frozen solid before being exposed.

• The X-rays move faster than the sample can disintegrate.

• A special shield protects the sample from damage.
