Nanotechnology medical fields sterilization Medical nanotechnology is a branch of nanotechnology which applies principles in this field to health care issues. Nanotechnology is a broad spectrum of scientific endeavors which involves manufacturing and machining which take place on a molecular scale. There are a number of potential applications for medical nanotechnology, and in its early phases, many people were quite excited about the huge changes which could occur in the medical world with the assistance of medical technology

Nanotechnology is not just about the size of very small things, it is the revolutionary science and art of manipulating matter at the atomic or molecular scale. Moreover  , it is about the structure and the ability of molecules to act . Research in needed to develop manufacturing techniques .

When matter is as small as 1 to 100 nanometers, many of its features can be easily change and have many unique feature both different from macro-matters and single atoms due to the quanta effect. the final objective of nanometer technology is to reach products of special functions with new physical and chemical features by making atoms, molecules behave differently, for example :the strength of ten times of iron could be very light.

Medical nanotechnology also makes cell repair on a molecular level possible, and provides a number of opportunities for medication administration. Drugs developed through nanotechnology could directly penetrate cells, for example, or nanoparticles could be designed to target cancer cells, delivering medication or providing a focal point for radiation. Medical nanotechnology can also be used to make biosensors which can be implanted into patients for monitoring, along with medical devices which are designed to be permanently implanted such as pacemakers.

Micro-organisms are a risk factor in many areas of life . They harm health and can disrupt work as in medical fields & food industrial process , which costs time and money. Fast and reliable disinfection and sterilization is a pre requisite to decrease the infection risk . Efficacy is not a must to be of high cost reduction and good compliance with legal threshold and good compliance with legal threshold  values

Because nanotechnology operates on such a small scale, it offers the opportunity to create precisely targeted surgical instruments, drug delivery systems, and implants. Nanobots, for example, could be used to perform a non-invasive medical imaging study inside the body, or to perform surgical procedures. Nanomaterials can also be implanted into the body; for example, someone with a badly damaged bone or joint could be treated with nanoparticles which would promote new growth, regrowing the damaged tissue.

Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes.

Todays manufacturing methods are very crude at the molecular level. Casting, grinding, milling and even lithography move atoms in great thundering statistical herds. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. Yes, you can push the LEGO blocks into great heaps and pile them up, but you can't really snap them together the way you'd like.

In the future, nanotechnology will let us take off the boxing gloves. We'll be able to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics. This will be essential if we are to continue the revolution in computer hardware beyond about the next decade, and will also let us fabricate an entire new generation of products that are cleaner, stronger, lighter, and more precise.

It's worth pointing out that the word "nanotechnology" has become very popular and is used to describe many types of research where the characteristic dimensions are less than about 1,000 nanometers. For example, continued improvements in lithography have resulted in line widths that are less than one micron: this work is often called "nanotechnology." Sub-micron lithography is clearly very valuable (ask anyone who uses a computer!) but it is equally clear that conventional lithography will not let us build semiconductor devices in which individual dopant atoms are located at specific lattice sites. Many of the exponentially improving trends in computer hardware capability have remained steady for the last 50 years. There is fairly widespread belief that these trends are likely to continue for at least another several years, but then conventional lithography starts to reach its limits.

If we are to continue these trends we will have to develop a new manufacturing technology which will let us inexpensively build computer systems with mole quantities of logic elements that are molecular in both size and precision and are interconnected in complex and highly idiosyncratic patterns. Nanotechnology will let us do this.

Nanotechnology is playing an increasingly major role in the healthcare industry. Examples include the use of nano-particles in cancer therapy and targeted drug delivery systems. Nanotechnology is also widely issued in tissue engineering applications.

This special issue is expected to provide a comprehensive overview of research and implementation issues of nanotechnologies in the medical field and is targeted for an audience of both researchers as well as practitioners. It will highlight key issues relating to medical, diagnostic and surgical applications of nanotechnology.

The papers are expected to discuss the current status and future prospects so that researchers can formulate new research topics related to nanotechnology. Practitioners and business personnel should be able to use the articles published in this special issue to gain foresight on the implementation of nanotechnology.
