Applications of Nanotechnology

What fields use nano-enhanced products? Cosmetics Textiles Electronics Food Sporting equipment ….and more! Enter information as best fits your class

Materials Nano-coated fibers Guitar strings Sunscreen Water & stain resistant Antibacterial Guitar strings Feels like non-coated Coated to improve strength Sunscreen Better UV protection Water resistant Transparent! Nano-coated fibers: Nanoscale coatings can be applied to fabrics to affect some properties but without changing the feel, texture or flexibility of the fabric. Silver ions have antibacterial properties. Silver nanoparticles embedded into fabrics/insoles can release ions, killing bacteria and helping to eliminate odors.

Sporting Goods Composites can make materials lighter and stronger Carbon (nanotubes and graphene) SiO2 nanoparticles Carbon nanotubes incorporated into adhesive allows paddle to be stiffer without increasing weight Silica nanoparticles fill voids in carbon fibrr composites increasing durability/stability – tennis raquet

Transportation Composites can make materials lighter and stronger Carbon fiber nano-composite hull Lighter materials for electric vehicles Nanocomposite is stiffer and reduces occurrence of cracks in hull. Velozzi supercar has 80% body made of carbon composites, makes cars both lighter and safer

Electronics - Computers Computing Hardware Processors – 14 nm Moore’s Law Moore’s law = The number of transistors on an integrated circuit (processor chip) will double every year. 14 nm = distance between features on chip Fabricated using advanced lithography

Electronics - Displays Organic - LEDs Organic molecules emit light = brighter Flexible Roll to roll processing Traditional LEDs are light by a white backlight and color is filtered by dye molecules. OLEDS emit light of different colors. Organic LEDs are like polymers and can be flexible if printed on a flexible conductive substrate Roll to roll processing = cheaper devices once optimized

Solar Cells Emerging Technologies: Thin Film Solar Cells: Organic CIGS, CdTe, Amorphous Si Emerging Technologies: Organic Dye Sensitized Solar Cell Quantum Dot Amorphous Si

Dye Sensitized Solar Cells Increased surface area / volume ratio of TiO2 nanocrystals allows enough dye to attach to generate electrons to power device. DSSC are not as efficient but nicer to look at!

Medicine Targeted and traceable drug delivery Enhanced imaging Sensitive detection Excess sugar displaces a dye molecule in the lens, making it change color; also UW/Microsoft http://www.dailymail.co.uk/health/article-2149276/Colour-changing-contact-lenses-replace-painful-skin-prick-tests-diabetics.html and http://www.uakron.edu/innovation/eyes.dot

Lab on a Chip Also called microfluidics Point of care diagnostics High throughput screening Device shown is for isolating cells to help speed up the process of genetic analysis. Its function can replace something like a FACS (fluorescence activated cell sorter) which is a large, expensive instrument.

Food SiO2 of TiO2 coatings Fat Clusters Packaging Undetectable by taste or small Increases shelf life Fat Clusters Increased surface area to volume Improved taste (surface area) Less fat (volume) Packaging Smart packaging: spoilage sensors Plastic bottles with improved barrier properties from nanoclay 3D printing allows microcircuits in milk cap that can sense food spoilage
