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. What is the primary propulsion source?Active motility of biological components, often utilizing flagellar mechanisms
2. What is the emergence of field?Significant research and development intensified in the early 2000s
3. What are biohybrid microswimmers?They are tiny robots that combine living bacteria with tiny non‑living parts. The bacteria swim and push the whole device through liquid, while the artificial part can carry drugs or respond to magnets.
4. How do bacteria make the microswimmers move?Bacteria have tiny tail‑like flagella that spin like propellers. The spinning pushes the whole device forward, giving it a natural way to swim.

Microscale: Referring to dimensions typically between 1 micrometer and 1 millimeter, often requiring magnification to observe.
Flagella: Long, whip-like appendages used by many microorganisms for locomotion.
Biocompatibility: The ability of a material or device to perform with an appropriate host response in a specific application.
Micro-Reynolds Number Regime: A flow regime at very small scales where viscous forces dominate inertial forces, leading to unique fluid dynamics.
