Cancer Therapies: Help by nanotechnology?
Among the controversial modern techniques belongs (like genetic engineering) nano technology. This is a collective term for the use or manipulation of very small structures (Greek nanos = dwarf): less than 100 nanometers (1 nanometer = 1 Millardstel = 10-9 m). Certainly we can and should also this research area is not sweeping condemnation – the questionability begins in this case where the risks are not sufficiently known. (From a study of the Allianz insurance to opportunities and risks, I had already reported elsewhere.)
An example of the cancer therapy might sense and benefits of nano technology.
In the treatment of tumors are usually several parallel strategies used – it may, however, the issue of compatibility and coordination.
Setting one means that the blood vessels of tumors destroy (so that they do not continue on its growth can be supplied), you can the other hand, the chemotherapeutic drugs (toxins that destroy the cancer cells) is not close to the tumor cells challenge, because this would be the transportation in the blood (of the now destroyed vessels) to use it.
Help create after recent research results, the Nano technology! You can see them as a “Trojan horse”. The famous “Massachusetts Institute of Technology (MIT) has also experimented successfully completed. These structures were created, the man himself as a “balloon in the balloon” imagine. In the inner balloon are the active ingredients of chemotherapy. The outer balloon contains the blood vessels destructive drug. The outer skin also gets a substance that the defense of the immune system lahmsetzt (otherwise would nano cell, the “balloon”, not through!).
Is the Nano only in the tumor cell arrived, the destruction of the blood vessels. At the same time solves the inner skin of the balloon (figuratively speaking), and the chemotherapeutic substances are freely and destroy the tumor itself
The MIT this procedure has already been tested in mice: It was shown that this procedure effectively than double other measures destroy tumor cells, the formation of new blood vessels and prevent the damage to the surrounding healthy tissue slows. The report, I took the health side of the BBC.
