What is Nano science?

Nano science is a science that a describes manipulation of chemical and biological architectures with dimensions in the range from 1 to 100 nanometres.

Who invented Nanotechnology?The word itself was coined by Professor Norio Taniguchi in 1974. The idea of manipulating atoms and molecules was first brought up by Richard Feynman in 1959

What is Nano science used forNano science has already impacted our lives with innovations such as stain-resistant fabrics inspired by Nano scale features found on lotus plants 

Nano science can be used to detect the early signs of cancer in patients.

Nano In NatureNanoparticles are being generated continuously by vegetation and sea spray in rural areasThere are Nano features on Geckos feet These Nano features enable them to climb and stick to almost any surfaceNano filters can produce clean

drinking water Nano filters can be used for water purification to provide clean drinking water without the use of chemicals.

Some species of butterfly have Nano features in their wings The Morph butterfly is one of these and many other butterfly species use Nano-scale light-interacting structures on their wing scales to produce colour.

Special filters and processes which allow nanoparticles to bind with the pollutants are the basis for these new developments, and may be particularly useful in cleaning up contaminated water.

Stronger and lighter materials created by nanomaterial's such as carbon nanotubes may also have an important positive environmental impact by making lighter weight cars and airplanes

Nano healthNano medicine research is coming up with new ways of diagnosing and treating health problems and discovering new ways of giving patients medicine to minimize side effects.

These clinical trials involve issues like sensors that might be able to smell cancer and gold Nano particles that might be able to detect early stage Alzheimer’s

Clinical trials are

being done today and

should be available

soon.

Benefits of the lab on a chip • Quicker diagnostics. • Greater control over analysis. • Less waste. • Small devices allow samples to be analysed at the point of need rather than a laboratory. • Uses in other areas:

industrial applications and environmental monitoring

Portable lab chips • Chips could be injected into the bloodstream. • Travel to diseased cells. • Diagnose. • Deliver medication.

A possible nano solution • Use of cantilevers a few hundred nm thin.

• In this system, micro-organisms are detected with nano-devices.

• Fighting disease causing organisms.

• Developing medical devices. • Faster diagnoses

Nanoscience in Health research

Nanotechnology and cancer treatment • Chemotherapy not specific.

• Nano drug delivery can directly target tumours

Magnetic nanoparticles • Some nanoparticles become magnetic in the presence of a magnetic field.

• Nanoparticles target cells-magnetic field makes them vibrate, heat up and destroy cancer cell.

– Clinical trials already happening! • MRI imaging for faster diagnoses

Nanotechnology and heart disease

• Nanopatch can bring dead heart tissue back to life. • Carbon nanofibres are excellent conductors of electrons. • Keeps heart beating steadily

Nanotechnology- potential health risks

• Where do particles go? – Do they stay in cells/blood stream?

• Are workers safe manufacturing them? • Where do we dispose of them? – Environment issues
