Nanotechnology in our lives; Is it true that good things come in small packages? Over the years, the available technology has increased dramatically. Technology has evolved from things that were once seen as incredible and mind-blowing, to common devices that are used every day and some of which are now part of us. Thanks to technology today we are able to examine and solve problems that 25 years ago were only a dream for many scientists. As we have increased our ability to use these devices, developments and advances in artificial intelligence and molecular technology have created a new form of technology; Nanotechnology. Nanotechnology is basically “an extension of existing sciences” (MH Fulekar 2010), only on a much smaller, nano scale. Nanotechnology is the understanding and control of matter at sizes between 1 and 100 nanometers, smaller than a strand of human hair, which is nearly 80,000 nanometers thick. figure 1 Using nanoscale science, phenomenal engineering, technological and medical ideas, it covers a whole range of various developments. Although it contributes to many areas of science, chemistry plays the most important role in its use and development. It involves building nanomaterials into defined, complex structures, atom by atom or molecule by molecule. Therefore, chemistry forms a basis for nanotechnology by providing tailor-made molecules and polymers. (3) All manufactured products are made up of atoms. “The properties of these products depend on how the atoms are arranged. For example, if we rearrange the atoms in coal, we get diamonds. If we rearrange the atoms in sand (and add a pinch of impurities) we get computer chips. If we rearrange by rearranging the atoms in the earth, water and air we get grass." (5) Nowadays… half of the article… one has to wonder what implications they might have on our health, since nanotechnology is a new kind of science. Nanotechnology can also allow us to create more powerful weapons that are very dangerous. Weapons are an obvious negative use of nanotechnology. Extending current weapons capabilities with the ability to create miniaturizing weapons, explosives and missile electronics would be deadly. However, even with nanotechnology, armies could also develop disruptors to attack physical structures or even biological organisms at the molecular level.(9) "At the instrumental level, there is also the possibility that nanotechnology could be used to develop chemical weapons and why be in capable of developing chemicals from the atom, critics fear that chemical weapons developed from nanoparticles will be more dangerous than current chemical weapons."
