For many, nanotechnology is viewed as merely a way to make stronger and lighter tennis rackets, baseball bats, hockey sticks, racing bikes, and other athletic equipment. But nanotechnology promises to do so much more. A more realistic view is that it will leave virtually no aspect of life untouched and is expected to be in widespread use by 2020. Mass applications are likely to have great impact particularly in industry, medicine, new computing systems, and sustainability. Here are some underlying trends to look for, many interconnected, and all expected to continue to accelerate.

1. Stronger Materials/Higher Strength Composites

The next generation of graphene and carbon nanotube-based devices will lead to even lighter but stronger structures than has been made possible by carbon fiber and will become increasingly obvious in cars, bicycles, and sporting equipment, says Clint Landrock, chief technology officer of NanoTech Security.

2. Scalability of Production

One big challenge is how to produce nanomaterials that makes them affordable.

3. More Commercialization

Over the next several years, significant advances are expected in carbon nanotube manufacturing technology, specifically in controlling the purity and structure, and in reducing costs due to economies of scale.

4. Sustainability

One main goal of the National Nanotechnology Initiative, a U.S. government program coordinating communication and collaboration for nanotechnology activities, is to find nanotechnology solutions to sustainability.

So, after coming across all the ideas, the application of nanotechnology in producing and managing energy seems to be the most feasible one. The option of organ production is innovative, but will always remained confined to patients of organ failure or similar cases. If efficient batteries can be made, it can also improve its use in health care. This proves that the chosen idea has a broader spectrum for application. And is also essential due to the possibility of some 'Global Energy crisis' in the near future.

Imagine if your heart or liver suddenly failed, and you could actually use repurposed stem cells from your own body to grow your own replacement organs. This has already been done by medical researchers.The easiest organs to create are “bags and tubes” such as blood vessels and bladders. The hardest to grow are dense organs such as the heart or liver, although novel techniques are being developed to grow even the most complex organs. Nanotech will help in making inert polymers and also, providing scaffolds for 'growing organs'

Not only this, nanotechnology can allow better ways to understand organs

.Based on the research made I think that the idea of Green nanotechnology is the most feasible one. With increasing population and an increase in the gravity of environmental problems, it is essential that any new technology that appears to be sustainable is encouraged. When it comes to sustainability, applications of nanotechnolgy can further be segregated into those dealing with production of energy and efficient electrical devices that save energy and management of wastes( by production of ecofriendly polymers).

I would like to emphasize more on the idea of application in energy sector. Special nanoscale materials could make batteries, fuel cells, and photovoltaic cells cheaper, more durable, and more powerful by exploiting the high surface area and quantum properties of existing substances produced as nanoscale particulates and novel materials like carbon nanotubes and quantum dots.

Nanotechnology is finding its place in the era of modern science. New fields are being researched everyday for its application. Some of the prominent areas of application in practical world are-

1)Nanomedicine-Nanomedicine seeks to deliver a valuable set of research tools and clinically useful devices in the near future.[2][3] The National Nanotechnology Initiative expects new commercial applications in the pharmaceutical industry that may include advanced drug delivery systems, new therapies, and in vivo imaging.

2)Green nanotechnology-

Green nanotechnology has two goals: producing nanomaterials and products without harming the environment or human health, and producing nano-products that provide solutions to environmental problems. It uses existing principles of green chemistry and green engineering[2] to make nanomaterials and nano-products without toxic ingredients, at low temperatures using less energy and renewable inputs wherever possible, and using lifecycle thinking in all design and engineering stages.

3) Energy applications of nanotechnology-

An important subfield of nanotechnology related to energy is nanofabrication. Nanofabrication is the process of designing and creating devices on the nanoscale. Creating devices smaller than 100 nanometers opens many doors for the development of new ways to capture, store, and transfer energy. The inherent level of control that nanofabrication could give scientists and engineers would be critical in providing the capability of solving many of the problems that the world is facing today related to the current generation of energy technologies

Currently, active research is going on on ways to apply nanotechnology in healthcare because of its feature of 'compactness'. Here are some examples of fields where nanotechnology can be used.

Organ transplantation: The main reason for low success rate of organ transplantation is the incompatibility found between the organ of donor and that of receiver. Even if a compatible donor is found, no one can guarantee a "reaction-free recovery".Nanotechnology can be used not only to prevent the cause of reaction, but also to create artificial organs. Extensive research is going on to create polymers similar to human tissues.

Better alteranatives for chemotherapy: Cancer treatment is often related with sureshot side-effects like excessive hairloss, diarrhoea,

during chemotherapy or radiation sickness in case of radiation therapy. Principles of nanomedicine can be used to directly interfering with the division of so-called 'mad cells' simply by binding to the genetic material responsible for the same.

Fighting against microbial pathogens: Bacteria as well as viruses are evolving.- getting more resistant to the present- day drugs. In order to increase their stay in the 'Host-cells'most notorious viruses use the strategy of cell mimicry. In Simple terms, it just changes itself in such a way that the drug does not identify and hence, doesn't act on it. Of course, there has to be some mechanism used by viruses to detect the presence of a drug. Nanomedicine can surely give us a way to fool its systems and win over deadly diseases like HIV-AIDS.

Atomic Layer Deposition(ALD) (AFM) A self-limiting, sequential surface chemistry that deposits conformal thin-films of materials onto substrates of varying compositions. ALD is similar in chemistry to chemical vapor deposition (CVD), except that the ALD reaction breaks the CVD reaction into two half-reactions, keeping the precursor materials separate during the reaction. ALD film growth is self-limited and based on surface reactions, which makes achieving atomic scale deposition control possible. By keeping the precursors separate throughout the coating process, atomic layer control of film grown can be obtained as fine as ~ 0.1 angstroms per monolayer.

Atomic Force Microscope (AFM) An instrument able to image surfaces to molecular accuracy by mechanically probing their surface contours. A kind of proximal probe. .... A device in which the deflection of a sharp stylus mounted on a soft spring is monitored as the stylus is moved across a surface. If the deflection is kept constant by moving the surface up and down by measured increments, the result (under favorable conditions) is an atomic-resolution topographic map of the surface. Also termed a scanning force microscope. [FS]

what is the need of survey on this topic? when we talk about survey on this topic,this question immidiately strikes our mind while the answer is obvious,that is,the developments in nanotechnology helps us to have a better understanding and an indepth approach about this field.Infact,developments in this field are like stairs which helps us to move higher and higher in our life and there is no end to these stairs and hence the more stairs we would step up the higher we would climb making a new pathway towards the wonderful future and we would be able to crush off most of the bigger challenges of our life as in today's world,our life is like a task to be performed by us and these developments in the field of nanotechnology are serving us like tools which are required by this task to be performed.The following questions would solve the purpose of this survey by hammering into our minds the importance of developments in this field :

1.what developments occured till now do you think have a great impact on your lives?

2.According to you, what is the scope of these developments in future?

3.Do you think that there is any area in which there is a huge scope of developments in the field of nanotechnology?If so,then why?

Scientists and engineers spend thousands of man-hours each year developing and innovating new products. Increasingly this research work is under the microscope and the person peering through the microscope may be a member of the public. A lot of very carefully planned research and development work can be undermined by a pithy remark in the press that may be misinterpreted by the public especially where new technology can be caricatured in an unhelpful manner. A social science vision recognises that, due to the complexity of the world within which nanotechnology functions, the solutions developed with scientific excitement and enthusiasm need to come with a health warning. Two further social science issues are ensuring privacy of information and technology fixes instead of better life style health choices. A public consultation project [3] was developed to enable the EPSRC to take account of a wide set of societal views and inform nanotechnology research trajectories for healthcare – creating a space through which citizens, scientists and stakeholders can engage in an informed debate on the public value, ethics and applications at an early stage. A further warning on the necessity of this approach is a recent press release concerning nanomaterials from the European Commission that recognises the benefits of nanomaterials, however, for consumer protection has called for urgent development of adequate testing protocols and metrology standards to assess the hazard of exposure to workers, consumers and the environment. Also included should be entire life cycle with accident cases and labelling (probably to REACH standards) using a multi-disciplinary approach.

Questions

1)For a long time effect,what will be the social benefit of nanotechnology?

2)Will the advancement of nanotechnology provide an economic breakthrough?

3)Is the development of nanotechnology has a further research future?

4)Will this technology save people?

5)How will nanotechnology promise the protection of the environment?

Why not?! A lot of brainstorming is going on this topic at present. Debates amongst scholars of the field are broadening the scope and the very definition of nanomedicine. On one hand, there are people saying that the concept of nanotechnology is making things smaller and hence, it has more to do with electrical equipments in healthcare. Another group of scholars says that the basic mechanisms of drug delivery and drug- target interactions is indirectly based on nanotech- making the concept broader.

The following questions can provide a basis for the survey. As nanotechnology is a relatively newer topic, with lack of information amongst common folks, the target audience has to be essentially research scientists , scholars, students and analysts of Nanotechnology. Questions:

1.What is your personal definition of nanomedicine and what are the sectors of medicine which will get the greatest benefits from this science/technology in the future?

2. In your opinion, what does differ nanomedicine from pharmacy or normal drug manufacturing?

3. In your opinion, do nanotechnology, and nanomedicine in particular, raise ethical and privacy concerns? If so, why?

4.Do you think that specific rules should be adopted for working environments where nanomaterials are created/deployed? Do you think that the biological sector deserves more attention in this regard?

5.Do you think that nanomedicine-related innovations in the realm of nanotechnology be the most complex to deal with due to the regulatory and societal issues that surround them? If so, why?

6. Do you think that nanomedicine research will be impaired or somehow harnessed by the results of environmental and health studies conducted on nanomaterials?
7.Do you think that nanotechnology innovations, in general, should deserve a different treatment as to their patenting and classification? And in the specific field of nanomedicine?

The survey can tell us different perspectives of nanotechnology and also the views of people involved in the field regarding nanomedicines

1.What is the impact of developments in the field of nanotechnology?

There is a huge impact of developments in the field of nanotechnology as these are improving the standard of our living as well as helping us in moving step by step with this fast moving world and hence,nanotechnology is moulding our lives and providing them new beautiful shapes like a clay and making our future as bright as the sun.

2.Why there is a need of developments in nanotechnology?

Today's world is developing with a lightening speed and we can't manage to keep pace with this fast moving world without these developments in nanotechnology.Our life has gradually become like a running vehicle while these developments in nanotechnology are like a fuel for that running vehicle.Thus without the developments going on in the field of nanotechnology,our lives will be like an earth without the water.

3.What can be the areas in which the developments in the field of nanotechnology can take place?

For finding the answer of this question,we have to explore as much as we can, in the field of nanotechnology.

However,there can be various areas in which the developments in the field of nanotechnology can take place.

Forexample:defence,medical sciences,agriculture etc.

When we talk about an emerging field-such as nanotechnology whose applications are being researched even today in a plethora of different fields, some questions are bound to arise. I've made an attempt to answer some of those. Such As:

1. WHY nanotechnology in medicine??

It should rather, be 'Why not nanotechnology' because with the world getting smaller, gadgets becoming smarter, it is more or less obvious to link nanotechnology with medicine and biology. With time, several new surgical techniques have been developed, using newer instruments which make operations much easier.

Apart from this, the very basic principle of drug delivery makes use of nanotechnology(as mentioned in the article).

2.WHAT is the scope of nanotechnology in this field??

Here, nanotechnology can be used in creation of artificial sensory receptors, treatment of fatal disease- like cancer, Searching for newer and safer medicines and the list continues.....

3.HOW does does it help in the field of medicine??

Nanotechnology essentially deals with making things smaller . Actually, apart from medicines, application in the field of electronics has exponentially increased the areas of usage. For example, pacemaker, a device used to deal with ' Cardiac arrhythmia' has great importance in healthcare is a product of nanotechnology.

4. So WH does it end?

The sky is the limit! "The greatest power of nanomedicine will emerge, perhaps in the 2020s, when we can design and construct complete artificial nanorobots using rigid diamondoid nanometer-scale parts like molecular gears and bearings. These nanorobots will possess a full panoply of autonomous subsystems including onboard sensors, motors, manipulators, power supplies, and molecular computers. "Says Robert A. Freitas Jr., A research fellow at Institute for Molecular Manufacturing. The statement also shows that development of nanotechnolgy in any single field is co-related with its advancement in other fields

When it comes to drugs and medicines, the mechanism of drug delivery is necessarily based on nanotechnology. However , with development in science and technology, there is a wide array of innovations in which nanotechnology peeps through in this field.

Nanotechnology can be used to make surgical tools. Scientists are building all sorts of devices that will hold, cut and mend very small parts inside your body—parts the size of a single cell, or even smaller.

Apart from this, Scientists have been making nanometer scale things that are based upon what we see in nature. This is called biomimetics—-copying things found in nature.

It turns out that cancer cells have a lot of folic acid receptors, proteins on the outside of a cell that bind folic acid. carbon nanotubes coated with folic acid, that is vitamin B are used to treat cancer. So the cancer cells bind folic acid coated carbon

nanotubes and then the carbon nanotubes get inside the cancer cell.

In today’s world many things are increasing at an extremely fast pace but among them the most considerable thing is the field of nanotechnology like a fire in a forest.

There is a huge application of nanotechnology in the field of agriculture as

Scientists have discovered the molecule that can act as a nanosensor for detecting pesticides in the crops which would help them in agricultural activities with proper usage of pesticides to protect the crops.

There can also be a huge application of nanotechnology in defence as scientist are putting their heart and soul to develop a liquid armour which would be lighter in weight and also solve its main purpose as it will be using the liquid molecules which on compressing can temporarily convert into the solid.

One of the most important applications is that various cloths are being made waterproof and stain free by embedding some molecules into the fibre which repels the water or oil on the surface of the fabric or a cloth.

Finally,we can conclude that the nano technology is like an ocean of knowledge and we just know a single drop of it.

Modern science needs a quantum leap and nanotechnology provided a wormhole travel for the leap. Nanotechnology is the science of developing small things. It is the technology of converting the macro substances into micro sizes , in the range of nanometres.The properties of the substances change at such a small level. It is going to be the the next revolution in materialistic science after the invention of plastic. Nanotechnology has already found its place in medical sciences. Doctors are using it to clear blockages in hearts and kidneys. Nanotechnology is being developed for stealth purposes by the armies of different countries. It is going to be the next future. Nanotechnology is the key of future for communication industry. It will change the way we live and interact with the present day technology. Nanotechnology is the quantum leap
