Find 10 nano-applications of interest to you. Post a brief description and a link for more info. For each application, explain the "nano" part based on the descriptions of what makes nano special from the nano.gov website: http://www.nano.gov/nanotech-101/special
1. Fabric: Nano-dry
Quantem Effect
Aquapel™ is the next generation in water repellency performance. Aquapel modifies fabric at the molecular level by permanently attaching hydrophobic ‘whiskers’ to individual fibers that elevate liquids, causing them to bead and roll right off the fabric surface. It features a hydrocarbon polymer which is both more ecologically friendly and economically smart. The result is excellent performance-liquid repellency that’s breathable, durable and fast drying- while remaining both fluorocarbon free and PFOA free.
- Repels the elements
- Resists spills
- Maintains breathability
- Eco-friendly technologys
2. Washing machine
Quantum Effect
http://en.wikipedia.org/wiki/Silver_Nano
Samsung home appliances, such as refrigerators or air conditioners, have a silver nano coating on their inner surfaces for an overall anti-bacterial and anti-fungal effect. As air circulates, the coated surfaces contact with the silver ions which can resist any airborne bacteria, which in turn suppress the respiration of bacteria, adversely affects bacteria's cellular metabolism and inhibits cell growth.[2][3]
Samsung says the silver nano technology sterilizes over 650 types of bacteria and that "Samsung WM1245A Washing Machine releases over 400 billion silver ions which penetrate deeply into fabrics of any kind and create a coat of sterilizing protection for a maximum of 99.99% disinfection and an added antibacterial effect of up to 30 days after washing".[4]
According to Paul Lipscomb, Product Manager, White Goods, Samsung Australia: "The Silver Wash system means that it's no longer necessary to soak clothes in additives or wash at extremely high temperatures in order to sanitise them. This combined with Samsung front loading washing machine's industry leading water efficiency ratings of up to 5A, creates a major saving on the long term cost of running the washing machine."[5]

3. Nano Pro Technology (NPT) in tires
Quantum / Surface Area
http://autos.aol.com/article/high-tech-tires/
With NPT we've been able to insert polymers that attach the to carbon black molecules and actually cause them to space themselves somewhat homogeneously. They're not touching each other, so you get a much cooler running temperature, which results in a significant reduction in rolling resistance. It also improves the traction."

Removes toxic or unwanted bivalent ions (ions with 2 or more charges), such as–Lead–Iron–Nickel–Mercury (II)
Millions of people have no clean water to drink. Nano-clay and nano-fibres are being used to create cheap, effective water filters for developing countries.
5. 3-D tape in televisions
5. quantum dot display
Quantum effect
http://en.wikipedia.org/wiki/Quantum_dot_display
is a type of display technology used in flat panel displays as an electronic visual display. Quantum dots (QD) or semiconductor nanocrystals are a form of light emitting technology and consist of nano-scale crystals that can provide an alternative for applications such as display technology. This display technology differs from cathode ray tubes (CRTs), liquid crystal displays (LCDs), but it is similar to organic light-emitting diode (OLED) displays, in that light is supplied on demand, which enables new, more efficient displays, which is enabling mobile devices with longer battery lives.
6. medicine
Art of Biology
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Nano-technology has produced better ways of delivering vital drugs to the right place in your body - but not in the shape of a tiny submarine! Nano-cages trap the drug molecules and then carry them to where they are meant to go.
7. Protective Armour
Surface Area
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
A new type of carbon fibre, developed at the University of Cambridge, could be woven into super-strong body armour for the military and law enforcement.
8. Renewable Energy
Quantum Effect
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Scientist have recently used nano-wires 200 times thinner than a human hair to create tiny solar power cells.
9. Smart Dust
Art of Biology
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Engineers have recently made a radio component the size of a virus, so maybe 'smart dust' will become a reality where smart particles are spread over a battle field to report back to base. Or the particles are placed in your body to report back on your health.
10. Computers
Quantum Affect
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Quantum computers, with processing devices at the atomic level, promise to be a million times faster than today's supercomputers
