Consumer Goods



These are applications with which we will come
into direct contact
Many different industries use Nanotechnology to
enhance their consumer goods
Food, Cosmetics, Household, Energy etc.
Household


Most notably, cleaning products (“easy to clean”)
Films that are applied to surfaces (countertops,
windows)

Titanium Oxide nanoparticle as part of these
films

These nanoparticles are able to use energy in
light to start a chemical reaction to kill bacteria
NANOSILVER

• Numerous uses because of their unique
size-dependent electrical and magnetic
properties
• Used in biotechnology, bioengineering,
textile engineering, and water treatment
because of its antibacterial/antifungal
properties
(Right: nanoparticle antimicrobial gel with
nanosilver that can be applied topically)
Cosmetics
-Sunscreen
-nano Zinc Oxide
-Anti-Aging Creams

Clothing

Textiles

Nanowhiskers help make fabric water and stain
resistant by causing water to bead up

Silver nanoparticles in fabric kill bacteria to make
it odor-resistant
Sports Equipment
-Golf Clubs
-Nanometal Coatings
-Tennis Rackets

Silicon Dioxide

Food

Superior Packaging

Silicate Nanoparticles
Zinc Oxide Nanoparticles
Silicate Nanoparticles in plastic
packaging can provide a barrier to
gases (oxygen) or moisture

Zinc Oxide Nanoparticles can
block UV rays and provide antibacterial protection when
added to plastic packaging
Ultra Fast Communications
• Varying voltage changes graphene’s absorbing
corresponding wavelength of light (infrared to
ultraviolet)
• Optical Modulators
• Theoretically reach 500 gigahertz (ultrafast
communication and computing)
• Previous attempts using phonics ineffective due to size
• Nanotechnology shrunk modulator from a few
millimeters to 25 microns
Graphene Optical Modulator
Solar Energy
• Provides more than enough energy for
earth
• Currently expense is a barrier
• Graphene layers now adopted
• Free flow of electrons
• Black in color absorbs heat→water produces
thermal energy
• Absorbs multiple wavelengths
• Cheap (less than $1/gram)
