Nanotechnology in Product Development

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.

BENEFITS AND APPLICATIONS

• Everyday materials, processes and food

• Electronics and Information Technology

• Sustainable energy

• Environmental remediation

• Medical and Health

• Transportation

NANOTECH IN EVERYDAY MATERIALS AND PROCESSES

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.

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

SUSTAINABLE ENERGY APPLICATION

1. Prototype solar panels are developed

ENVIRONMENTAL REMEDIATION APPLICATIONS

1. detect and clean up environmental contaminants.

-Coatings

-Sprayers

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,

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

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.

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.

ENVIRONMENTAL REMEDIATION APPLICATIONS

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

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
