  8. BIOLOGY AND MEDICINE The biological activity of nano- and nanostructured materials can be facilitated to make established treatments more efficient, to find cures for diseases where there is no treatment, to remediate environmental problems, and to shift frontiers in technological approaches. Focus Areas in Nano Research (1) BIO and PHARMA NANOBIOLOGICAL PHOTOSYNTHESIS BIOSENSORS Using a nanosensitive quarz crystal microbalance with dis-sipation to study interactions with applications for bio-sensors Fluorescence from chloro-phyl in an artificial vesicle intended to power a nano-machine BIO LABELLING Colloidal gold nanoparticles to visualize antigen-antibody interactions in medical and veterinary diagnostic tests J. Limson, RU R. Sparrow, CSIR gold D. Du Plessis, ARC and Vision Biotechnology (Pty) Ltd

  9. POLYACRYL-NITRILE YARN produced by electro spinning GOLD NANOPARTICLES on zinc oxide produced by reduction of gold hydroxide E. van der Lingen, Min-tek E. Smith, SUN SILICON NANOPARTICLES produced by thermal catalytic pyrolysis CVD PALLADIUM NANOPARTICLES in a polyaniline based composite pro- duced by soft chemical synthesis SILVER NANOPARTICLES produced by wet chemical synthesis M. Scriba CSIR M.S. Scurrell, WITS N. Revaprasadu, Uzulu Focus Areas in Nano Research (2) CARBON NANOTUBES SYNTHESIS The physical and chemical properties of nanomaterials are different to those of the corresponding bulk material. To make use of this feature, arranging atoms using chemical and biochemical processes to form nanomaterials like particles, rods, wires, tubes, can be performed applying a multitude of synthesis methods. C. Arendse, CSIR composite 4000 x

  10. POLYMER CARBON NANOTUBE COMPOSITE showing a honeycomb like arrangement of CNTs inside the polymer matrix ACTIVE NANOCOMPOSITE COATING temperature dependence of the surface plasmon resonance in a nano-gold vanadium oxide optical coating METAL MATRIX NANOCOMPOSITES production of an aluminium composite containing noble gas nanoprecipitates S. Sinha Ray, CSIR M. Maaza iThemba, LABS D.T. Britton, UCT Smart Materials Focus Areas in Nano Research (3) NANO-CLAY COMPOSITES exfoliated polystyrene - (Ethyl-MMT) nano-composite containing 5.7% clay Change the properties of materials by giving them a nanostructure, or using nanostructured coatings which respond to changes in their environment, or create new composite materials with previously unknown properties R. D. Sanderson, SUN

  11. The very large surface of nanostructured materials enhances chemical reactions for the benefit of more efficient industrial processing, the removal of noxious substances in the environment, and also for energy and fuel production ELECTROCATALYTIC Pt NANO COMPOSITEElectrodes for hydrogen production L.Petrik UWC FUEL CELLS FC catalysts on the surface of carbon nanotubes GOLD-BASED CATALYSTS show good catalytic activity towards CO oxidation and other reactions INDUSTRIAL PROCESSING catalysts with controlled particle size and shape for optimization of industrial catalytic processes M. Claeys UCT T.R. Tshikhudo, Mintek V. Linkov, UWC CATALYSIS Focus Areas in Nano Research (4)

  12. NANOELECTRONICS PHOTONICS AND PHOTOVOLTAICS SILICON NANOPARTICLES used in inks to produce elelctronic devices by simple printing, e.g. solar cells The use of nanostructured materials and nanoscale phenomena in electronic, photonic and electrical applications provide the opportunity to overcome the limitation in performance dictated by traditional technologies, and provide new approaches for cost efficient solutions M. Harting, UCT NANO PHOSPHORS SrAl2O4:Eu2+,Dy3+ phosphor nano-particles provide light as soon as they are illuminated QUANTUM DOTS fabricated using AFM lithography on an MBE-grown GaAs/AlGaAs heterostructure R. Nemutudi, iThemba Labs H.C. Swart, UFS Focus Areas in Nano Research (5)

  13. TB Nano-drug Delivery TB is the leading cause of death in SA: • Nano-based drug delivery systemcapable of slowly releasing the drug in a controlled and sustained manner • Reduce dose frequency from daily to once a week • Reduce treatment time • Treat MDR and XDR-TB • To address other diseases which fall under non-compliance • Develop human capacity and infrastructure • Successfully encapsulated 4 of the leading anti-TB drugs using double emulsion solvent evaporation - spray drying technique

  14. Nano R&D in SA Industries

  15. SA Nano Global Footprint South Africa has active collaborations with a number of institutions in various countries

  16. Possible Areas of Collaboration • Human Capital Development • Exchange programmes (students, post-docs) • Collaborative Research Projects • Advanced NanoMaterials Development • Nanotechnology for health, water, energy applications and minerals beneficiation • Development of Nanoindustry • Development of a Technology Platform: large scale production of nanoparticles, nanoelectronics

  17. Way Forward • Planned ICSTI-SA Workshop: Nanotechnology/Nanomaterials, Feb/March 2010, South Africa • Key Objective of Workshop: - To identify common areas of collaboration in advanced nanostructured materials • Outcomes: - Agree on areas of collaboration - Identify modalities (infrastructure, exchange visits, etc.) of collaboration
