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
