  1. Nanotechnology – The Future Technology Done by: Liau Yuan Wei (3A317)

  2. Nanotechnology? • Nano = Very tiny • Study of the controlling of matter on an atomic scale • 1 to 100 nanometer!!! Nanomaterials? • A study of materials with morphological features on the nanoscale

  3. Nanoparticle? • Particles having one or more dimensions of the order of 100nm or less • Building blocks of nanotechnology • Bridge between bulk materials and atomic or molecular structures • They form nanomaterials

  4. How to create them? High Gravity Controlled Precipitation (HGCP) • Developed based on fundamental mass transfer principles • Micro mixing of the reaction phases is achieved in microseconds • Reaction phases brought together under a high gravity environment.

  5. HGCP

  6. Advantages • Scalability: Cost effective scale up for large scale production of nanomaterials • Control: Good control over quality, particle size, distribution and particle shape • Versatility: Can create any type of nanomaterials

  7. One Real-Life Example • NMT announced today that it has signed an exclusive licensing agreement with WinsunnyPharmafor the use of HGCP Technology to manufacture a generic version of a world-wide hyperlipidemia-controlling drug in China with a potential market size of over US$900 million.

  8. VS Nanogold An example of a nanoparticle

  9. Properties Gold Nanogold • A shiny, yellow metal • Does not tarnish, • Face centred cubic structure • Non-magnetic • Melts at 1336 K. • Can turns red, blue, yellow and other colours. • A very good catalyst • A semiconductor • Melting point decreases dramatically as the size decreases

  10. How? • It is possible to tailor the properties of their nanoparticles assemblies by varying the size and composition of the particles. • By heating these nanoparticle arrays at different rates, it introduces instability into the structure of nanogold. (Form nanowires) • Scientists in Japan discovered 10 years ago that gold displays fantastic catalytic abilities when it is shrunk to 3 to 5 nm in size.

  11. Uses Staining of Glass • The Romans found that they could get several colours out of the same gold particles simply by adding water and diluting the potion. • Rediscovered by Michael Faraday in the 1850s

  12. Uses Saving the Environment • Nanogold technologies are showing great promise in providing solutions to a number of environmentally important issues. • E.g: greener production methods of chemical feed-stocks, countering pollution and water purification.

  13. Uses Catalysts • Can prevent the release of high amounts of mercury into the atmosphere. • Constructing cost effective and efficient fuel cells, a key 'clean-energy' technology of the future.

  14. Uses Tumors • Using nanogold for tumourtargeting technologies to deliver drugs directly into cancerous tumours. • Gold nanoparticles are introduced into the veins and guided by a spectroscope to locate problem tumours; they are then injected into the tumour along with an antibody to stop the tumour’s ability to grow • Can be used to do a quick test for cancerous cells • Also can be used in X-Rays to provide a better vision of the human body

  15. Uses Advanced Technologies • The key driver of future electronics solutions. • Shown to offer functional benefits for visual display technologies such as touch sensitive screens. • Potential usage for advanced data storage technologies such as advanced flash memory devices.

  16. Uses Cancers • Scientists are able to do these: • Using gold nanoparticles to locate and kill cancer cells inside the body without harming healthy cells • Collecting and characterizing tumour cells in a person’s bloodstream with microfluidic devices • Determining which gases exhaled in a person’s breath indicate the presence of breast cancer • Detecting ovarian cancer from patterns of metabolites found in a drop of blood
