There is very little public awareness of nanotechnology. One survey found that 49% of Americans haven’t heard anything about nanotechnology, 26% heard just a little, 17% heard some, and only 7% heard a lot. To this date, regulatory bodies like the United States Environmental Protection Agency (EPA), the United States Food and Drug Administration (FDA), and the European Food Safety Administration (EFSA) have not created any specific regulations for products containing nanomaterials. The full effects of nanomaterials on human and animal health are currently largely unknown. Free nanoparticles can be particularly toxic to humans and animals due to their ability to penetrate the bodily defenses.
Scientists can create almost anything from the so-called building blocks of matter behind nanotechnology. A nanometer is one-billionth of a meter or one-hundred thousandth the diameter of a human hair. Nanotechnology is the creation and manipulation of tiny objects at the level of molecules and atoms. At the nano-scale, the laws of chemistry and physics work differently, and materials develop unique properties, not seen at normal size. Opaque materials, such as copper and zinc, become transparent; stable materials, such as aluminum, become explosive; and solids, such as gold, turn into liquids. There are more than 800 consumer products on the market made using nanotechnology. A tableware set contains a nano silver coating that kills bacteria, aiming to prevent food-borne diseases. A toothpaste contains nanoparticles that help remove plaque and provide minerals to protect against tooth decay. A golf club shaft is made from “nano composite technology” to be stronger and lighter weight. Major food companies, such as General Mills, Kraft, Nestlé, PepsiCo, Cadbury-Schweppes, and Unilever, are researching and developing nano food. Other agricultural giants conducting nanotechnology research include Dupont, BASF, and Cargill, but, surprisingly, not Monsanto.
Nanopaticles are more chemically reactive than larger particles. Because they are so small, they have greater access to the human body than larger particles. They can be inhaled, penetrate skin, gain access to tissues and cells, and cross the blood-brain barrier. Researchers in the United States found that in tests on mice, sunscreen nanoparticles over stimulated brain cells, which could lead to brain damage. Antibacterial nano food packaging and nano-sensor technologies may also harm beneficial bacteria in our bodies and the environment, and lead to the development of more harmful bacteria. it is likely to further entrench fossil fuel and chemical intensive industrial agriculture and encourage continued reliance on large monoculture farms, resulting in the loss of small farms and biodiversity.
HOW TO USE THE PREPOSITION “BEYOND”

Beyond measure: to a very great extent.
Beyond one’s means: beyond one’s budget or income.
Beyond one’s years: more intelligent than other people your age
Beyond the pale: outside the bounds of acceptable behavior.
Beyond par: selling at more than their face value
Beyond possibility: unable to be done or to happen
Beyond a reasonable doubt: no other logical explanation can be derived from the facts
Beyond belief: astonishingly great, good, or bad; incredible.
Beyond beautiful: wondering if it was possible
Beyond budgeting: beyond command-and-control toward a management model that is more empowered and adaptive
Beyond bearing: too painful, unpleasant
Beyond suspicion: definitely not guilty of doing anything wrong
Beyond satisfaction: satisfied up and above what you would have regularly been
Beyond scope: outside the relevant range, extent of action, inquiry, etc. in question
Beyond shadow of a doubt: be certain that it is true
Beyond salvation: responsible for saving you from harm, destruction, or an unpleasant situation
Beyond words: not to find words to express ones emotions
Beyond reason: to a foolishly excessive degree.
Beyond recognition: so as to be no longer recognizable
Beyond reckoning: scratched so many times you can’t count
Beyond reproach: such that no criticism can be made
