  19. 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. Some socks have been developed with the silver in to help people who suffer from athletes foot. Antifungal/antibacterial Properties

  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? http://www.bbc.co.uk/learningzone/clips/nanotechnology-used-in-sunscreen-manufacture/6004.html

  25. 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?

  26. Some have antibacterial, antiviral and antifungal properties Could penetrate skin and cause undesired side-effects Preparation of certain catalysts Easily released into the environment Nanoparticles Unusual properties, leading to new uses There is a lot that we don’t know about nanoparticles at the moment. Much more research is needed before their use becomes widespread Advantages and disadvantages of using nanoparticles Disadvantages Advantages GCSE Science Chapter 6

  27. Nanotechnology Questions • What is nanotechnology? • Describe two uses of nanotechnology. • What is buckmister fullerene? How is it useful? • What are the concerns about the use of nanotechnology?
