Nanomaterials
Narrated lesson · press play
Shrink a material down to a few atoms across and it gains astonishing new powers. Learn what nanotechnology and nanomaterials are, why their tiny size gives them special properties like antimicrobial silver, and where we use them — from medicine to sportswear.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 3.4):
- State that nanotechnology is used to produce nanomaterials such as graphene and fullerenes
- State that nanomaterials have particle sizes between approximately 1 and 100 nanometres (nm) in one dimension
- State that the small size gives properties different from bulk materials or individual atoms/molecules (e.g. silver nanoparticles are antimicrobial)
- State examples of applications of nanotechnology (medicine, electronics, environment, consumer products, sporting goods)
