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!
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!
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.
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?
Antifungal/antibacterial Properties
Some socks have been
developed with the
silver in to help people
who suffer from
athletes foot.
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?
Advantages and disadvantages of using
nanoparticles

Nanoparticles
There is a lot that we
don’t know about
nanoparticles at the
moment. Much more
research is needed
before their use becomes
widespread
Nanotechnology Questions
1.What is nanotechnology?
2.Describe two uses of
nanotechnology.
3.What is buckmister
fullerene? How is it
useful?
4.What are the concerns
about the use of
nanotechnology?
