In last decades Nano technology attentioned as an applied technology. This technology is producing and controlling materials, tools and new systems in molecular-atomic size that created from combination of physics, chemistry and biology sciences. The new Nano size materials have new benefits and characteristics that did not had before. Nano technology have different kinds of operations, like: alimentary, drugs, Medical diagnosis, bio technology, electronics and computers, communication, transportation, energy, safety, health and environment, aero spacing and etc. unique features of every Nano martial like size, shape, bio compatibility, solubility are important factors in biological efficiency.
History
A) Medical development and Nano Medicine appearance
Nano Medical is applications of approaches, theories, devices and structures in Nano scale in order to identify, prevent or treat diseases through detection, repair damaged tissues in bio-molecular level. The main goal of Nano medicine is pathology and treatment facilities in molecular and tiny molecular scale. According to research of Majo et al, the main fields of Nano medicine applications that have informatics challenges include: drug delivery, implantable devices, diagnostics, prevention and therapeutics.
Nanoparticles can be used as carriers of drugs or certain organic molecules. Nano delivery is transfer of Nano scale objects into the body and to penetrate them into cells. The high cost of drug development with a range of three thousand to 11.5 million dollars is one of the obstacles in progress of this area. Many implantable devices in Nano scale, such as Nano-robots can be designed to monitor the diseases. For example, Nano scale devices can be attached to the patient and...

Over the years, surgery has made tremendous progress while changing human perspective; viewed as “no more science than butchery” a couple of centuries ago to now considered to be a solution for many health care problems threatening humans, like cancer, heart disease and kidney failure. Nevertheless, surgery has not been perfected to a level that provides successful results every time it is performed on patients. For example, surgery done to remove tumors in cancer patients result in only 45% of individuals to be cured. However, in order to be successful, the surgical procedure has to be carried out incredibly precisely and incomplete removal of tumors can decrease survival rate. Therefore, surgeons have to be able to recognize diseased tissue and distinguish it between healthy tissues. But even with the use of radioactive tracers and visuals, surgeons are not able to identify the exact site of the unhealthy tissue and its boundaries. Thus, almost 40% of the time cancerous cells are left behind because even the best qualified surgeons are not successful at the nanotechnological scale of tissue.
Cost effectiveness and noninvasiveness seem to be a theme in developing preventative treatments of coronary artery disease. A study presented by the Journal of Magnetic Resonance Imaging proposes that the use of coronary wall MRI would encompass both of these factors. These MRI images compared coronary artery thickness of symptomatic and asymptomatic patients. It was found that these images could successfully detect artery wall thickness in asymptomatic patients who would have otherwise not been screened for risk factors.

Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...

Regenerative medicine targets the conservation and development of organ function. The modification of tissues is obtained by linking living cells with materials that work as scaffolds to support cell generation. Nanotechnology is the means that feeds the material structure that simulate biological ones and additionally provide a direct delivery system. The functionality of nanotechnology for regenerative medicine is primarily due to its small unit size according to the International System of Units, one nanometer is one-billionth of a meter. The unit size allows for the technological apparatus to navigate the bloodstream and target and fix damage cells in tissues.
Cheminformatics term was coined for the first time by F.K. Brown and it's defined as "the field of chemistry that integrates chemical data with analytic and molecular design tools finding the 'best- fitting' compounds to address particular targets". It can be called also "chemoinformatics", "chemioinformatics" or "chemical informatics". In silico techniques are used in cheminformatics for a wide range of applications, such as in rotational drug design or in drug diversity, using the structure for predication of the activity and in virtual screening. This was first applied in the making of the period table
By convention, the field of healthcare research was entirely occupied by physicians and doctors. They were the ones who came up with new methods to treat diseases and get better results from diagnostic tests. Technology, on the other hand, was always looked at as a way to solve problems that we faced that didn’t pertain to the medical sector. It was employed to enhance the quality of life and make day to day work easier. But as technology progressed, so did the areas of application. The structural balancing techniques which were previously used to hold a building steady were now being used to develop near-perfect artificial joints and prosthetic limbs. Transparent polymers, developed to enhance robotic vision, were being suggested as a candidate for an artificial lens for the human eye. Before anyone could even understand what was happening, engineering had taken up the mantle to further medical technology to dizzying new heights.

“Computers play a key role in almost every sphere of life” (Berry, Terrie). Without them, everything would be different. People all around the world own or used a computer. Whether you are a professional in technology or just an average person, computers are still very important in your everyday life. “No other technology has accessed the world like computers and the use of the Internet have” (Maddox, Amanda). Without computers, consumers would not be able to do half the things as quickly as we can. Advances in computer design have increased its use for different industries, especially in the medical field.
