What is nanotechnology in plants?

hi,

I feel our question is too pre-mature, I feel.

Nanotechnology can be applied in any field and in many many ways.

for example in plants you can

1) use nano iron / magnesia / any other nutrients as a feed for them.

2) use nano scale imaging devices(like AFM, SEM, STM, etc ) to study and understand their structure and other properties.

3) cure their diseases by injecting medicines thru nano needles at the right or specific section / part.

4) extract some valuable or commercially important chemicals or substances from a tiny part of the plants etc.

like this one can add a lot it will soon touch million if I go more specific.

If my answer is too premature or this is not what you expected, or to give your esteemed feedback kindly mail me at prithvij2004<at>gmail<dot>com

Who discovered nanotechnology?

Nobel-prize-winning physicist Richard Feynman gave a lecture titled "There's Plenty of Room at the Bottom" on December 29, 1959 at an American Physical Society meeting at Caltech. It considered the possibility of direct manipulation of individual atoms, and is widely regarded as a milestone in the development of nanotechnology.

Practical nanotechnology started in the 1980s with the development of atomic force microscopes, which are capable of manipulating individual atoms.

K. Eric Drexler published Engines of Creation: The Coming Era of Nanotechnology in 1986, expanding on the concepts of nanotechnology, and laying out a hypothetical roadmap to achieve it.

What is nanotechnology?

Nanotechnology is the technology of building devices, such as electronic circuits, from single atoms and molecules. Nano means "small", of the order 10-9m, so nanotechnology is (among other things) generally a conversation about new science that creates machines the size of molecules.
a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to create computer chips and other microscopic devices.


Nanotechnology is a term for devices and chemicals engineered at the nanometer scale. Broadly, it encompasses two separate ideas:

"Molecular nanotechnology" is the assembly of structures to complex, atomic specifications by means of mechanosynthesis.

"Nanoscale materials" encompasses any manipulation of matter at lengths from 1 to 100 nm, but often includes things on the micrometer scale.

Nanotechnology refers to the smallest scale of the engineering, not necessarily the size of the finished product.
Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic and molecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research.

(ref:wikipedia)
nano refers to something that is of the order 10-9. A nano-meter is therefore a very small unit of length. Nano technology refers to very small machines, small enough to work at a cellular or even molecular level. Check out the SF story Blood Music by Greg Bear.
Nanotechnology is the the branch of technology that deals with dimensions and tolerances of less than 100 nanometers, esp. the manipulation of individual atoms and molecules. (The definition from my dictionary) In my words, Technologies that deal with how things behave when they are very small. VERY small. A nanometer (nm) is one BILLIONTH of a meter. Wow! One strand of hair is about 100,000 nm. For more information, vist http://www.futureforall.org/nanotechnology/nanotechnology.htm I hope this is what you were looking for!

Why is nanotechnology becoming popular?

Building with Atoms Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nanomachines. Humans still have a lot to learn about the idea of constructing materials on such a small scale. Consumer goods that we buy are made by pushing piles of atoms together in a bulky, imprecise manner. Imagine if we could manipulate each individual atom of an object. That's the basic idea of nanotechnology, and many scientists believe that we are only a few decades away from achieving it. Photo courtesy NASA, Ames Nanogears no more than a nanometer wide could be used to construct a matter compiler, which could be fed raw material to arrange atoms and build a macro-scale structure. Nanotechnology is a hybrid science combining engineering and chemistry. Atoms and molecules stick together because they have complementary shapes that lock together, or charges that attract. Just like with magnets, a positively charged atom will stick to a negatively charged atom. As millions of these atoms are pieced together by nanomachines, a specific product will begin to take shape. The goal of nanotechnology is to manipulate atoms individually and place them in a pattern to produce a desired structure. There are three steps to achieving nanotechnology-produced goods: Scientists must be able to manipulate individual atoms. This means that they will have to develop a technique to grab single atoms and move them to desired positions. In 1990, IBM researchers showed that it is possible to manipulate single atoms. They positioned 35 xenon atoms on the surface of a nickel crystal, using an atomic force microscopy instrument. These positioned atoms spelled out the letters "IBM." The next step will be to develop nanoscopic machines, called assemblers, that can be programmed to manipulate atoms and molecules at will. It would take thousands of years for a single assembler to produce any kind of material one atom at a time. Trillions of assemblers will be needed to develop products in a viable time frame. In order to create enough assemblers to build consumer goods, some nanomachines, called replicators, will be programmed to build more assemblers. Trillions of assemblers and replicators will fill an area smaller than a cubic millimeter, and will still be too small for us to see with the naked eye. Assemblers and replicators will work together like hands to automatically construct products, and will eventually replace all traditional labor methods. This will vastly decrease manufacturing costs, thereby making consumer goods plentiful, cheaper and stronger-hear the echo? Not to dispute the answer but right now the ARMY is actively searching for technology to put solar cells into fabrics to charge the batteries used by army people for a variety of uses

Is it better for a chemistry graduate to get a Ph.D in organic chemistry or nanotechnology?

*If a person has completed the graduation and wanted to do the Phd, it would in my opinion be better to do the Phd in organic chemisty because it will be easier for a person who has studied the subject.

*But if he goes for nanotechnology in this subject you should also have the knowlege of physics as nanotech deals with the particle size less then 100 nm and it is nothing to relate with the chemisty unless u create some new compound using nano particles

What is the difference between nanoscience and nanotechnology?

NANOSCIENCE OR NANOTECHNOLOGY Nanoscience and nanotechnology involve studying and working with matter on an ultra-small scale. Nanoscience and nanotechnology encompass a range of techniques rather than a single discipline, and stretch across the whole spectrum of science, touching medicine, physics, engineering and chemistry. Nanotechnology is the science of the extremely tiny. It involves the study and use of materials on an unimaginably small scale. Nano refers to a nanometre (nm). One nanometre is a millionth of a millimetre or about one eighty thousandth the width of a human hair.

Nanotechnology describes many diverse technologies and tools, which dont always appear to have much in common! Therefore it is better to talk about nanotechnologies, in the plural. One thing that all nanotechnologies share is the tiny dimensions that they operate on. They exploit the fact that, at this scale, materials can behave very differently from when they are in larger form. Nanomaterials can be stronger or lighter, or conduct heat or electricity in a different way. They can even change colour; particles of gold can appear red, blue or gold, depending on their size. These special attributes are already being used in a number of ways, such as in making computer chips, CDs and mobile phones. But researchers are progressively finding out more about the nanoscale world and aim to use nanotechnologies to create new devices that are faster, lighter, stronger or more efficient. Nanotechnologies are widely seen as having huge potential in areas as diverse as healthcare, IT and energy storage. Governments and businesses across the world have started to invest substantially in their development. However, alongside this excitement some people have started to ask how these technologies will contribute to shaping the world we live in. WHAT IS NANOTECHNOLOGY? Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. WHAT IS NANOSCIENCE? Nanoscience is the study of phenomena on the scale of ~ 1-100 nm. Nanotechnology is the ability to create and control objects on this same scale with the goal of preparing novel materials that have specific properties and, thus, functions. Although current nanotechnology research is primarily exploratory, and it may take years to realize many of the goals envisioned, the prospect for significant applications is high. It is thus clear and justified that nanoscience, as a prerequisite to nanotechnology, should receive long-term fundamental support.

What is the difference between nanotechnology and nuclear technology?

Nanotechnology deals with working with very small things. A nanometer is 10-9 meters. Think of a machine that is composed of 100 molecules, taliored to do a specific task like break up plaque in an artery, injected into the body by the thousands. This site http://www.crnano.org/whatis.htm

shows a machine comprised of 15,342 individual atoms making three gears.

Nuclear technology generally deals with the fissioning (splitting) of atoms to release energy although it also deals with using the energy of radioactive decay for various tasks such as treating cancerous tumors and sterilization of food.

What are the applications of nanotechnology?

Pretty much anything you can think of. It has application in so may fields, including medicine, technology, computers, weapons, etc. One of the most promising things about it at least in the near future is carbon nanotubes. Using nanotech, they can create a material out of these nanotubes that is 100 times stronger than steal and 10 times lighter. In terms of applications, creating nanorobots that can be injected into your bloodstream that seek out cancer cells individually and destroy them, or that carry 10 times more oxygen than your regular red blood cells and therefore allow you to hold your breath for 4 hours... etc.

Honestly, you would do better to just search nanotechnology on answers.com and find out all the applications. What's the point in posting a question on answers.com when all the info is already on answers.com?

What are the disadvantages of nanotechnology?

Global monetary crisis, loss of jobs, oil becomes worthless, diamonds become worthless, atomic weapons more destructive and accessible. In relation to health problems, it is so minute that its existence in the hand is much unnoticed. The risk of inhaling this could be very dangerous, due to which it can be a cause of death.

The medical advantages are change of body appearance, stops aging process, immortality, painless child births, and universal immunity like aids, flu and end of sickness.

The industrial advantages are automatic pollution cleanup, expanding computer technology by making it faster and smaller in size. The social advantages include, reproducing extinct animals and plants, safe and space travel, higher education, molecular food synthesis, to mention a few.
The unknown risk or different properties of chemicals when they are nano size.

Milk is an example of nanotechnology. The exhaust of trucks is an example of nanotechnology. The seeding of rain clouds is nanotechnology (now known to be harmful to the environment).

What is the impact of nanotechnology on society?

Nanotechnology is not a product like a microchip or an automobile. It is a process that harnesses the unique properties of materials at the 1-100 nanometer scale to develop new products. Nanotechnology has the potential to profoundly impact our lives in a similar fashion as the implementation of the moving assembly line by Henry Ford in 1908. It was Ford's streamlined manufacturing process that dramatically lowered the price of production and made automobiles affordable for most Americans. These manufacturing processes were implemented across the country and helped to fuel the industrial revolution. Many feel that nanotechnology will have an impact of this magnitude.
