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.
