What is nanoscience?

• A nanometer (nm) is 1,000,000,000 (1 billion)
  times smaller than a meter.
• Nano-science is the study of particles that have
  the size of 1 to100nm.
• Your finger nails grew a nm while reading this!

20
Imagine a nanoparticle was the size of a football.

• A chicken would
• be the size of earth
• A flea would be
• the size of Derby.
• A virus would be the same size as a human!

21
Why are we interested in nano-science?

• Nanosized particles can produce NEW properties in
  materials
• These properties are different to their behaviour
  in large scale eg silver
• Nanoparticles are so tiny that they have a huge
  surface area for a small volume.

22
Is nano-science about in our lives today? YES!!

• Lots and lots of things that you have used this
  morning have used nanoscience straightners,
  toothpaste, phones, makeup.
• Silver is very widely used - nano sized silver
  particles have antibacterial, antiviral and
  antifungal properties.
• Where could these be used?

23
Antifungal/antibacterial Properties

• Some socks have been developed with the silver
  in to help people who suffer from athletes foot.

24

• Nano-sized titanium dioxide absorbs and reflects
  UV light while being transparent to visible
  light.

Why is this useful? Where could be use this?

Buckmisterfullerene

• Fullerenes are carbon incredibly small carbon
  based molecules. They can be used for
  strengthening materials (for example sports
  equipment) and are sometimes used as a way of
  delivering drugs into the body.
• What type of bonding is this likely to contain?
