💊 Nanomedicine

Unit 3 · Nanomaterials in use · 9 min

Nanoparticles can wrap drugs and deliver them where the body needs them, reducing side effects. mRNA vaccines, for example, use lipid nanoparticles to protect the mRNA. Sunscreens often use zinc-oxide or titanium-dioxide nanoparticles. New drugs and materials need strict safety testing.
