INTRODUCTION

this summary will focus on nanotechnology, a science that is not very old but has a great importance to all in the sense that from this science that has been one of the greatest discoveries in history, a new form to see that around on a scale not previouslyimagined, the science generated every day to development of technologies that in one way or another involved in our lives planning a better future.

So when you select this item related to this topic so interesting, detailing the concepts of this science to learn properly and use all the knowledge that you transmit to us, especially a new era in which the science of nanotechnology will greatlyvalue and represent the evolution of human development in technology.

OBJETIVES

GENERAL PURPOSE

Learn about the importance of nanotechnology in human and technological progress of civilization.

SPECIFIC OBJECTIVES

- Know what nanotechnology is and its scope so broad.
- Recognize that science and science of the future.
- Know their origins or early in our civilization.Nanotechnology: The Promise and Peril of Ultratiny Machines

Nanotechnology is a field of applied science devoted to the control and manipulation of matter at less than a micrometer scale, ie at the level of atoms and molecules (nano). It is unusual that such manipulation occurs in a range of one to one hundred nanometers. There is a small idea of what can be a nanobot nanobot knowing that a about 50 nm isthe size of 5 layers of molecules or atoms, depends on what is done nanobot.
molecular machines are the ultimate purpose of nanotechnology in which if managed properly would be a great development for our civilization in which many countries are still living in underdevelopment therefore the duty to use this science for the benefit of mankind
The past few years have seen several breakthroughstoward the dream of realizing machines that control matter at the scale of molecule.We need to think seriously now about the opportunities and hazards they will bring.In Nature, molecular machines already exist. Plants and animals are, at the lowest level, assemblages of such”nanomachines”(a nanotener is a billionth of a meter).The most prominent of these nanomachine are, of caurse, DNA and RNAand the enzymes that assist in the reproduction and repair of cells and in the fabrication of proteins.

With adequate funding, researchers will soon be able to custom-build single molecules that can store and process information and manipúlate or fabricate other molecules, including more of themselves, this may accur before the turn of the century.
We can say at this time what might be thelimits of what such nanotechnology might make posible. Some have suggested that it will bring the”end of economics,”ushering inan age of almost unlimit abundance of marvelous new things. It is possible that cannot inprove very much on what natural carbón-based terrestrial life has already alchieverd, at least under terrestrial conditions. However, one cannot help but believe that we can probably dofarbetter when can control the exact placement of every atom in structures ranging from small molecules to giant systems of humano r even planetary dimensions.

Some of the most important benefits we could bring these innovations of nanotechnology would be:
* the first benefits of nanotechnology is likely to be the ability to produce materials that are extremely pure, indeed, perfectly...
