* Nanoparticles are so small that they can easily penetrate into the skin and thus help in repairing the skin tissues. It is because of this factor that you can prevent skin aging by using the products which have the nanotechnology built into it.
* This technology is also used in preventing the hair loss and graying issues.
* Sunscreens and some anti-aging products are the main cosmetic products on the market currently being made using nanotechnology. They are designed to penetrate the upper layers of the skin and stimulate new skin cell production which gives skin a new, plump, and youthful appearance.
* We all know the cosmetic range from L'Oreal which has brought the fantastic wrinkle-free creams for the aged women who want to look elegant and gorgeous. The wrinkle-free creams have given the immediate results because the products contain nanosiomes of Pro-Retinol A.
* Some of the nanoparticles such zinc oxide and titanium dioxide have been included in sunscreen.
* The products that use this nanotechnology are costlier as compared to others.
* Some of the products that they have introduced which incorporate the use of nanosomes are Biotherm Age Fitness Nuit, Vichy Reti C, and Revitalift Double Lifting

The advantages of nanotechnology
One of the basic principles of nanotechnology is positional control. At the macroscopic scale, the idea that we can hold parts in our hands and assemble them by properly positioning them with respect to each other goes back to prehistory. we celebrate ourselves as the tool using species.
At the molecular scale, the idea of holding and positioning molecules is new and almost shocking. However, as long ago as 1959 Richard Feynman, the Nobel prize winning physicist, said that nothing in the laws of physics prevented us from arranging atoms the way we want: “…it is something, in principle, that can be done; but in practice, it has not been done because we are too big.”
What would it mean if we could inexpensively make things with every atom in the right place?
* For starters, we could continue the revolution in computer hardware right down to molecular gates and wires — something that today’s lithographic methods (used to make computer chips) could never hope to do.
* We could inexpensively make very strong and very light materials: shatterproof diamond in precisely the shapes we want, by the ton, and over fifty times lighter than steel of the same strength.
* We could make a Cadillac that weighed fifty kilograms, or a full-sized sofa you could pick up with one hand.
* We could make surgical instruments of such precision and deftness that they could operate on the cells and even molecules from which we are made — something well beyond today’s medical technology.
The list goes on — almost any manufactured product could be improved, often by orders of magnitude.
What will we be able to make?
Nanotechnology should let us make almost every manufactured product faster, lighter, stronger, smarter, safer and cleaner. We can already see many of the possibilities as these few examples illustrate. New products that solve new problems in new ways are more difficult to foresee, yet their impact is likely to be even greater. Could Edison have foreseen the computer, or Newton the communications satellite?
1. Improved transportation
* Today, most airplanes are made from metal despite the fact that diamond has a strength-to-weight ratio over 50 times that of aerospace aluminum. Diamond is expensive, we can’t make it in the shapes we want, and it shatters. Nanotechnology will let us inexpensively make shatterproof diamond (with a structure that might resemble diamond fibers) in exactly the shapes we want. This would let us make a Boeing 747 whose unloaded weight was 50 times lighter but just as strong.
* Today, travel in space is very expensive and reserved for an elite few. Nanotechnology will dramatically reduce the costs and increase the capabilities of space ships and space flight.2 The strength-to-weight ratio and the cost of components are absolutely critical to the performance and economy of space ships: with nanotechnology, both of these parameters will be improved…3 Beyond inexpensively providing remarkably light and strong materials for space ships, nanotechnology will also provide extremely powerful computers with which to guide both those ships and a wide range of other activities in space.
2. Atom computers
* Today, computer chips are made using lithography — literally, “stone writing.” If the computer hardware revolution is to continue at its current pace, in a decade or so we’ll have to move beyond lithography to some new post lithographic manufacturing technology. Ultimately, each logic element will be made from just a few atoms.
* Designs for computer gates with less than 1,000 atoms have already been proposed — but each atom in such a small device has to be in exactly the right place. To economically build and interconnect trillions upon trillions of such small and precise devices in a complex three dimensional pattern we’ll need a manufacturing technology well beyond today’s lithography: we’ll need nanotechnology.
* With it, we should be able to build mass storage devices that can store more than a hundred billion billion bytes in a volume the size of a sugar cube; RAM that can store a mere billion billion bytes in such a volume; and massively parallel computers of the same size that can deliver a billion billion instructions per second.
3. Military applications
* Today, “smart” weapons are fairly big — we have the “smart bomb” but not the “smart bullet.” In the future, even weapons as small as a single bullet could pack more computer power than the largest supercomputer in existence today, allowing them to perform real time image analysis of their surroundings and communicate with weapons tracking systems to acquire and navigate to targets with greater precision and control.
* We’ll also be able to build weapons both inexpensively and much more rapidly, at the same time taking full advantage of the remarkable materials properties of diamond. Rapid and inexpensive manufacture of great quantities of stronger more precise weapons guided by massively increased computational power will alter the way we fight wars. Changes of this magnitude could destabilize existing power structures in unpredictable ways. Military applications of nanotechnology raise a number of concerns that prudence suggests we begin to investigate before, rather than after, we develop this new technology.4
4. Solar energy
* Nanotechnology will cut costs both of the solar cells and the equipment needed to deploy them, making solar power economical. In this application we need not make new or technically superior solar cells: making inexpensively what we already know how to make expensively would move solar power into the mainstream.
5. Medical uses
It is not modern medicine that does the healing, but the cells themselves: we are but onlookers. If we had surgical tools that were molecular both in their size and precision, we could develop a medical technology that for the first time would let us directly heal the injuries at the molecular and cellular level that are the root causes of disease and ill health. With the precision of drugs combined with the intelligent guidance of the surgeon’s scalpel, we can expect a quantum leap in our medical capabilities.

Nanotube Applications
The properties of carbon nanotubes have caused researchers and companies to consider using them in several fields. For example, because carbon nanotubes have the highest strength to weight ratio of any known material, researchers at NASA are combining nanotubes with other materials into composites that can be used to build lightweight spacecraft.
Another property of nanotubes is that they can easily penetrate membrances such as cell walls. In fact, nanotubes long, narrow shape make them look like miniature needles, so it makes sense that they can function like a needle at the cellular level. Medical researchers are using this property by attaching molecules that are attracted to cancer cells to nanotubes to deliver drugs directly to the diseased cells.
Another interesting property of nanotubes is that their electrical resistance changes significantly when other molecules attach themselves to the carbon atoms. Companies are using this property to develop sensors that can detect chemical vapors such as carbon monoxide or biological molecules.These are just a few of the potential uses of carbon nanotubes.

Nanotechnology and Multi-Scale Simulations
In the past couple of decades, the technology available has increased exponentially. We are able to examine and solve problems now that were only a dream to many scientists 20-25 years ago. As we increase our ability to discover and expand we are also facing new problems every day. These problems come as we delve further into the microscopic and atomistic world. We know how many materials act on the macro scale and we can model different simulations because of that knowledge. As we get into the micro scale and attempt to discover the actions of the atoms as they act with each other we have difficulty simulating the results. This is where the study of Harold S Park helps. It is a study about bridging multi scales for the discovery of how nano wires act and other atomistic applications. The bridging scale couples finite element simulations with molecular dynamic simulations and puts it into two dimensions. The paper takes the reader through a mathematical derivation and two separate problems, one involving wave propagation and one involving dynamic crack propagation. Both of these problems are analyzed mathematically and visually. The point of this study is to create a scale between the atomistic and continuum simulations. Another simulation that Harold talked about during his presentation was the simulation of a gold nanowire and how its atoms acted as a force was placed upon the wire. The wire was attached at one end and it was pulled at the other. As the wire was stretched it reached a point when the atoms in the wire aligned themselves and then finally snapped into two pieces. The amazing thing about the nano-wire was that it was actually stronger than a large hand held macro-scaled gold wire. It is in this technology that major advances in will be reached in the upcoming years.
According to Moore’s Law, if the technology used today is not transferred to the molecular level by the year 2015, then we are very behind. The computer companies are very interested in nanotechnology because it will enable them to create whole computers and such on the molecular level, leaving the rest of the actual machine to be designed any way the consumer would like. This technology involves the specific alignment of atoms to create a machine. This is counter to the normal design of machines, where a large machine makes a smaller one, and so on down the line. This requires the atoms to be placed and then systems of atoms can be used to create a machine or operator. Another aspect of nanotechnology of concern and interest is the self-replicating of atoms, or of molecular machines. This idea is similar to all of the atoms making up a tree; the atoms make up cells, which then self replicate and then join together to form the whole tree. These self-replicating molecules are essentially miniature manufacturing plants. They have something to build on the molecular level, something the eye cannot immediately see. The challenge is creating such a molecule and then having the ability to control it. If the molecular machines have the ability to self-replicate then one must be able to control the process. The idea that a self-replicating machine can do major damage is seen in the viruses that harm the human body. There must be a way to control the molecular machines so they do not act the same way and are harmful to the environment or humans.
The advancements of nanotechnology have a large impact of the field of medicine because of the possible ability to replicate on an atomistic level. Nanotechnology has the potential to replace many of the modern medicinal practices today. Modern medicine uses large handheld instruments and techniques that require a person to handle them or apply them. The idea of nanotechnology is that one can operate on and internal organ without using a scalpel. They have the ability to enter into the body without causing scarring or incisions. The possibility of introducing a molecule that is computer guided into the human body is the ultimate product. The molecule will be guided through the body to the point of disease of trauma and then have it self-replicate to treat the problem, all computer guided. Nanotechnology will in the future be the way medicine and surgery is practiced, but for now the needs to simulate what is happening are ultimate.

Nanotechnology in Medicine
Applications of nanotechnology in medicine currently being developed involve employing nano-particles to deliver drugs, heat, light or other substances to specific cells in the human body. Engineering particles to be used in this way allows detection and/or treatment of diseases or injuries within the targeted cells, thereby minimizing the damage to healthy cells in the body.
The longer range future of nanotechnology in medicine is referred to as nanomedicine. This involves the use of manufactured nano-robots to make repairs at the cellular level.
Faster, lighter computers possible with nanotechnology
Smaller, lighter computers and an end to worries about electrical failures sending hours of on-screen work into an inaccessible limbo mark the potential result of Argonne research on tiny ferroelectric crystals.
"Tiny" means billionths of a meter, or about 1/500th the width of a human hair. These nanomaterials behave differently than their larger bulk counterparts. Argonne researchers have learned that they are more chemically reactive, exhibit new electronic properties and can be used to create materials that are stronger, tougher and more resistant to friction and wear than bulk materials.
Improved nano-engineered ferroelectric crystals could realize a 50-year-old dream of creating nonvolatile random access memory (NVRAM). The first fruits of it can be seen in Sony's PlayStation 2 and in smart cards now in use in Brazil, China and Japan. A simple wave of a smart card identifies personnel or pays for gas or public transportation.

The Use of Nanotechnology in Space Travel
One of the big problems not fully appreciated with current ideas in nano technology research is the energy requirement for the development of shuttles and using it to carry the bots to other planets. First of all, the design of the shuttle would have to be very intricate because it would have to be able to manage to intense cold since it has to travel farther and farther away from the sun. And as for the probes that are going to build a base for colonization, it requires a new type of energy unlike solar power because as it travels farther, there would not be enough solar energy to make the bots function. Battery-charged energy would also fail because the probes are designed to stay on the planet long enough to build the base. A new type of energy that the group created is some type of regenerative energy that is built inside the probes. This allows the probes the period of time to build the base.
Another requirement or idea that is needed for our invention that is not present in the world today is some sort of advanced satellite transmission. Since the probes have to travel very far, it has to be able to transmit information that is collected from its exploration on the planets. The present technology does not allow satellite transmission, for example, in Pluto. That is the reason why we need new and improved satellites. Another method is to place better satellites that are able to withstand extreme weather changes, between the planets in intervals. For example, we would position a satellite at Saturn and one near the Earth. The probe would be able to send information from Pluto to the satellite near Saturn. Then the satellite would transmit the info to the satellite located near Earth.
Technology has evolved from ideals once seen as unbelievable to common everyday instruments.
Computers that used to occupy an entire room are now the size of notebooks. The human race has always
pushed for technological advances working at the most efficient level, perhaps, the molecular level. The
developments and progress in artificial intelligence and molecular technology have spawned a new form
of technology; Nanotechnology. Nanotechnology could give the human race eternal life, or it could cause
total annihilation

Nanotechnology
Nanotechnology is a group of emerging technologies in which the structure of matter is controlled at the nanometer scale, the scale of small numbers of atoms, to produce novel materials and devices that have useful and unique properties. Some of these technologies impose only limited control of structure at the nanometer scale, but they are already in use, producing useful products. They are also being further developed to produce even more sophisticated products in which the structure of matter is more precisely controlled. The Foresight Nanotechnology Challenges focus on applying these developing technologies to solving important world problems.
it is the creation of functional materials, devices and systems through control of matter at the scale of 1-100 nanometers, and the exploitation of novel properties and phenomena at the same scale; nanotechnology is also called molecular manufacturing. Nanotechnology is a result of the combination of different scientific fields such as physics, biology, engineering chemistry, and computer science in addition to many more. The foundation of nanotechnology is that atoms make up all things in our world; which can be manipulated to produce almost anything.
It is the development of atoms in a certain object. Nanotechnology has become very popular in the past few years. It is a way to rebuild the systems of life. To make systems move faster than ever before. Nanometer is about 10 times the size of an atom. Each of these has a huge effect on a system. Still there are questions out there that keep people wondering how important nanotechnology is to us. Many wonder how will it affect them and if we should continue this researchNanotechnology is defined as “the development and use of devices that have a size of only a few nanometers. Research has been carried out into very small components many of which depend on quantum effect and many involve movement of very small number of electrons in their action. Such devices would act faster than larger components.
It is an anticipated manufacturing technology giving thorough, inexpensive control of the structure of matter. The term has sometimes been used to refer to any technique able to work at a submicron scale
Molecular manufacturing will enable the construction of giga-ops computers smaller than a cubic micron; cell repair machines; personal manufacturing and recycling appliances; and much more.
A basic definition: 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.
