NANOTECHNOLOGY IS A..

field of Applied Science whose theme is the control of matter, its properties on an atomicand molecular scale.

MEDICINE8

FUTURE TREATMENTS

Nanodevices can make gene sequencing more efficient. It will revolutionize the specificity of diagnostics and therapeutics,

No operations, No more pills and chemotherapies,

Just one quick injection,

The nano sized machine communicate and target millions of different foreign bodies/ matters that may have developed in the body,

It will search and destroy foreign objects, and rebuild the bodies vital cells.

Nanotechnology has been a boon for the medical field by delivering drugs to specific cells using nanoparticles. The overall drug consumption and side-effects can be lowered significantly by depositing the active agent in the morbid region only and in no higher dose than needed. This highly selective approach reduces costs and human suffering.

FUTURE CANCER TREATMENTS

Nano molecules will travel and kill the cancer

Cancer cells can be killed by Magforce nonotheroperies, Nano xray therapies eliminatingpainful side effects of chemotherapy;loosinghair, hearing, etc..

Destroying tumor without killing healthy cells

No addition of toxics to body

FUTURE TREATMENTS CONT…13

New formulations and routes for drug delivery, optimal drug usage. (High consumption, lower side effects, cost and suffering)

‘Gene gun’ that uses nanoparticles to deliver genetic material to target cells

Tissue engineering: More durable, artificial tissues and organs Bones can be regrown on carbon nanotube

scaffolds

Sensors for early detection and prevention

NANO ELECTRONICS ANDCOMPUTING

14

PastShared computing thousands of people sharing a mainframe computer

PresentPersonal computing

FutureUbiquitous computing thousands of computers sharing eachand everyone of us; computers embedded in walls, chairs, clothing,light switches, cars….; characterized by the connection of things inthe world with computation.

APPLICATIONS CONT..

Cleaning- Super washing machines, Nano materialized clothes with special properties, Eg: Super hydrophobic

Security- Nano sensors, high security uniforms: Institute for Soldier Nanotechnologies (ISN) at Massachusetts Institute of Technology

Energy- Advanced Solar panels (24 hours working), fossil fuel replacements with high efficient cells

Many more…

NANO MANUFACTURING16

• Carbon Nanotubes• Nanostructured Polymers• Optical fiber performs through sol-gel

processing of nanoparticles• Nanoparticles in imaging systems• Nanostructured coatings• Ceramic Nanoparticles for netshapes.

NANOTECHNOLOGY IN SPACE

Improvements in shuttle Lighter weight and smaller in size Nano sensors and Nano robots Use of laser sails Micro and Nano rovers for planetary exploitation

Benefits to Astronauts Nano suits, Nano food : No refrigeration, Protection from

bacteria and diseases, Lighter.

Cheaper space flights

Nano satellites

Will be 90% lighter, Greater Strength, Greater Safety margin due to Dimondiode fibers.
