Science is defined as the body of knowledge obtained based on a specific method. Science is research, which was later described in an orderly way, providing expertise in a field. It is how to achieve new knowledge, considered valid until there is no rebuttal. This indicates that science is not an unquestionable truth.
Features that identify science: systematic, cumulatively, methodical, interim, verifiably, specialized product of an open and scientific research.
From the Greek Tekne, which means technical, trade, and logos, which means science and knowledge.
The concept Technology covers a wide range of techniques, processes and knowledge, we are used to construct and design objects which are met with a host of needs of human beings.
Consequence of technology is the science and engineering, where many of the advances beyond the concepts outlined.
Nanotechnology, shortened to "nanotech", is the study of manipulating matter on an atomic and molecular scale. Generally nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension, and involves developing materials or devices within that size. Quantum mechanical effects are very important at this scale.
Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale.

Recent PublicationsNew device detects hazardous substances in water
A device for the rapid analysis of liquids on the content of hazardous substances - such as heavy metals - has been developed by researchers, who have used a method based on polymer optodes, very small plastic matrices that can be made sensitive to specific substances by means of special reagents. The matrices change color and their intensity depending on the concentration of the substance. The device is mobile, can carry out analysis in situ even at low temperatures, and its cost is many times less than the price of a spectrophotometer, the most used device for chemical analysis.

Iron nanoparticles make immune cells attack cancer
Iron nanoparticles can activate the immune system to attack cancer cells, according to a study. The nanoparticles, which are commercially available as the injectable iron supplement ferumoxytol, are approved by the Food and Drug Administration to treat iron deficiency anemia.
