Nanotechnology is the engineering of functional systems at the molecular scale, manipulating atoms and molecules that are 80,000 times smaller than the width of a human hair. It has applications in everyday materials and processes, electronics, sustainable energy, environmental remediation, medicine, health, transportation, and cosmetics. In cosmetics, nanotechnology is used in mineral UV filters, nanocapsules, nanosilver and nanogold for antibacterial properties, and buckyballs for free radical scavenging in expensive face creams. Nanoparticles can also detect and help clean environmental contaminants and purify water.

2. WHAT IS NANOTECHNOLOGY?
• Nanotechnology is the engineering of functional systems
at the molecular scale.
• Nanotechnology is the science of manipulating atoms and
molecules in the nanoscale - 80,000 times smaller than
the width of a human hair.

4. BENEFITS AND APPLICATIONS
• Everyday materials, processes and food
• Electronics and Information Technology
• Sustainable energy
• Environmental remediation
• Medical and Health
• Transportation

5. NANOTECH IN EVERYDAY MATERIALS AND
PROCESSES

6. NANOTECH IN COSMETICS
1. Mineral-based cosmetic ingredients with nano-sized
dimensions
• Some cosmetic products, such as sunscreens, use mineral-based
materials and their performance depends on their particle size. In
sunscreen products, titanium dioxide and zinc oxide, in the size
range of 20 nm, are used as efficient UV filters.

7. NANOTECH IN COSMETICS
2. Nanocapsules
• Nanocapsules are submicroscopic particles that
are made of a polymeric capsule surrounding an
aqueous or oily core. It has been found that the
use of nanocapsules decreases the penetration
of UV filter octyl methoxycinnamate in pig skin
when compared with conventional emulsions

3.
Nanosilver and Nanogold
• antibacterial properties of nanosilver in a range of applications.
• underarm deodorants with claims that the silver in the product will
provide up to 24-hour antibacterial protection.
• Nano-sized gold is used in disinfecting the bacteria in the mouth
and has also been added to toothpaste.

4. Buckyballs
• Buckminster fullerene, C60, is perhaps the most iconic
nanomaterial and is approximately 1 nm in diameter. It has found
its way into some very expensive face creams. The motivation is
to capitalize on its capacity to behave as a potent scavenger of free
radicals

12. SUSTAINABLE ENERGY APPLICATION
1. Prototype solar panels are developed

13. ENVIRONMENTAL REMEDIATION
APPLICATIONS
1. detect and clean up environmental contaminants.
-Coatings
-Sprayers

14. OMNIYO NANO 223 COATING
• ACTIVELY KILLS all viruses (SARS, H1N1, HFMD)
• STOPS mold growth on surfaces
• PREVENTS ODORS from clothing, beds, pets, linens
• ELIMINATES VOCS* and toxic gases from furniture
• PROTECTS SURFACE from UV radiation & static
• PREVENTS PHOTOCATALYSIS
• To achieve the best results for application on large surface areas and or
commercial settings,

15. SONO-TEK ULTRASONIC SPRAY
Some common nanolayer deposition applications
include:
• Anti-reflection coatings onto solar glass
• Anti-stain or other protective coatings onto float
glass
• Anti-scratch coatings onto eyeglass or other
lenses

16. ENVIRONMENTAL REMEDIATION
APPLICATIONS
2. Nanotechnology could help meet the need for affordable, clean
drinking water through rapid, low-cost detection of impurities in
and filtration and purification of water.

17. ENVIRONMENTAL REMEDIATION
APPLICATIONS
3. Nanoparticles are used to clean industrial water
pollutants in ground water through chemical reactions that
render them harmless, at much lower cost than methods
that require pumping the water out of the ground for
treatment.

18. Z-LOYTM
• engineered zero valent metal powder suspensions (zero-valent
iron [aka zvi, nZVI], copper, magnesium, zinc, and others). In situ
remediation with Z-LoyTM injected into the subsurface, facilitates
the elimination of toxic substances, including:
• Halogenated solvents, including TCA, TCE and PCE
• Halogenated aromatics including PCB and pesticides
• Metallic substances including chromates and arsenates

20. CONCLUSION
• Nanotechnology is an innovative science that includes the design,
characterization, production and application of structures, devices and
systems by controlling shape and size at the nanometer scale. This
widespread use of nanoscale materials is due to the fact they obtain
newer properties which differ from the large-scale particles. These
altered properties include color, transparency, solubility and chemical
reactivity, making the nanomaterials attractive to the food, Electronics
and Information Technology, Sustainable energy, Environmental
remediation, Medical and Health, Transportation, cosmetics, and
personal care industries
