DefinationA nanometer is a billionth of a meter. Itís difficult to

imagine anything so small, but think of something only 1/80,000 the width of a human hair. Ten hydrogen atoms could be laid side-by-side in a single nanometer. 

Nanotechnology is the creation of useful materials, devices, and systems through the manipulation of matter on this miniscule scale. The emerging field of nanotechnology involves scientists from many different disciplines, including physicists, chemists, engineers, and biologists.

There are many interesting nanodevices being developed that have a potential to improve cancer detection, diagnosis, and treatment. 

Application in various FieldsElectronics.Medical or Healthcare.Textile.Food Industries.Agriculture.Environment.Energy and Water managementAdvanced materials

Challenges of NanotechnologyWith advanced electronics and communication fear to

privacy.With Bio-nanotechnology fear of biological weapons.Environmental problems, waste of nano industries will

not be easy to decompose.Genetic engineered crop require strong pesticides and

insecticides.With advancement in medical death rate will reduce it

means increased population and then there will be shortage of food.

Genetic EngineeringRecombinant DNA

GENETIC ENGINEERINGwith nanotechnologyFor centuries, humans have altered plants and animals by selective reproduction. As a result, we have a wide range of domestic animals and plants grown for food.Direct genetic modification is a relatively new process based on a set of technologies that alter the genetic makeup of living organisms, including animals, plants, bacteria, or fungi by inserting genes rather than using cross-breeding and selection techniques. The purpose of the modification of the genes is to derive certain benefits. movie

ApplicationsScientists have worked on some interesting combinations:Spider genes were inserted into goat DNA, in hopes that the

goat milk would contain spider web protein for use in bulletproof vests.

Jellyfish genes lit up pigs' noses in the dark.Artic fish genes gave tomatoes and strawberries tolerance to

frost.Field trials have included:Corn engineered with jellyfish genes (Stanford University)Rice engineered with human genes (Applied Phytologics)Corn engineered with hepatitis virus genes (Prodigene)Potatoes that glowed in the dark when they needed watering.

Ethical IssuesLike every technology bio-nanotechnology is having some

negative impact on word which need to be resolved first before taking the benefit from it, and these are.

Uncontrolled genetic results or mutation.New business controversies.the genetically modified organisms remains stable in artificial

condition inspite of natural environment.Sex ratio may vary because of selection of sex. Nature is more perfect designer.Cloning reduces genetic diversity.Cloning will be psychologically harmful to the child.Cloning will be physically harmful to the child.

End of existing Biodiversity

Mutation in Gene

There may come unwanted results

And some time totally new disease so we are creating danger for our self.

Genetic Disorder

With genetic engineering there are chances of genetic disorder means it will end the all genetic information and species because it is difficult to survive against the nature.

Gene Cloning

Gene cloning will create new threat to human life

Sex ratio vary dramatically because of selection of boy or girl at birth

Cloning reduces genetic diversity

GM FOODGenetically modified crop demand more strong pesticides and insecticides which harm the ground water and get involved in our food chain and then causes human disease.

Business Controversies

Domination of world food production by a few companies

Increasing dependence on industrialized nations by developing countries
