Show hintHide hint
Think about how nanoparticles behave differently when they enter a biological environment.
Question 2.
How do nanoparticles commonly enter cells?
Show hintHide hint
Consider the mechanisms cells use to take in substances.
3Question 3.
What is the role of the protein corona in nanoparticle behavior?
- It makes nanoparticles invisible to cells.
