Nanotechnology: Medicine, Materials and Research
When you hear the term, nanomaterials, what comes to your mind? Remember, when you were first introduced to the Periodic Table of Elements? Well, you were being acquainted with the many names, signs and symbols of nanomaterials. Some of which are giving scientists ways to create the possibility of becoming invisible.
Now, we know that some of these materials are good for our everyday use. We need oxygen everyday. Some are nutrients which we need for our health, wealth, and well-being. Some are utilized to provide heat/light for our everyday usage. Then there are those that we should stay away from, or be very careful as to the quantity and quality of it's use, or not at all. Nanomaterials are already present in certain cosmetics, sun block lotions, and anti-aging cosmetics. Although some persons may have allergic reactions, most go away when usage stops. However, ingesting nanomaterials is a different story. However, there are currently industries who practice the usage of these tiny particles for the purpose of certain foods to have a longer shelf life. Although we often hear of the many preservatives that go into our food nowadays, I can't say that I have actually heard of someone ingesting, specifically, nanomaterials. There can be some very harsh adverse effects involved upon ingesting them. They are known to cause damage to the brain, heart and lungs; as well as being a cause of some birth defects. And have been known to cause cancer, when cancer is not already present (their research and exploratory finding re: cancer shall be discussed shortly). Remember, it has been found that some industries are implementing their use in the foods we consume today, but it is not being reported to the Food and Drug Administration.
Nanoparticles (by azonana)
Tiny particles (nanomaterials) have thus far done wonders destroying proteins which are responsible for cancerous tumors. RNA (ribonucleic acid, nucleotides which are present in all life cells) are delivered to cancer patients via nanotechnology, known as (RNA interference), and has been successful in destroying cancer cells. Any excess of nanomaterials used in this process are passed out of the body upon urination. This is, obviously, great news for the cancer patient, whom it helps. Due to the concern of their overall safety usage and long-term health improvements, much research, tests and experimentation is still needed.

The Role of the Government
It is the role of the government to keep us from being unknowing and unwilling participants in the experimentation of nanomaterials. They also know that as technology advances, clinical trials will legally and illegally continue. Therefore, funds have been allocated for both the purpose of protecting the general public from the prohibited use of these materials, as well as for further research and experiments to determine if the possible miraculous outcomes from their usage should be continued.
