Gold nanoparticles determine breast cancer

Researchers at Purdue University have developed a way to detect and measure cancer levels in a living cell using gold nanoparticles.






Professor of the University Joseph Irudaya uses nanoparticles of precious metal to determine the breast cancer stage of the disease. This is due to the analysis of specific signal that goes from the gold particles under the influence of light.

As explained by the Professor, the simple yet sophisticated method can be used to identify cancer in one cell, and you can see how she is aggressive.

"Being able to determine the number of these genetic molecules could help clinicians provide better and more individual approach to the treatment of cancer patients. Using this method, we can identify a needle in a haystack, and we can determine there are five needles in that haystack or there are 50," he added.

Gold nanoparticles due to their unique physical and chemical properties are of great interest to scientists.

In modern medicine, gold has started to be applied in the diagnosis and treatment of several diseases, including malignant tumors.

In addition to the fairly common chemotherapy, which uses colloidal solutions of radioactive gold, today there is a brand new modern method, which provides for the introduction in tumor tissue microscopic gold nanocapsule and exposure to infrared rays.

While the cancer cells die, while healthy tissue remains intact.

In experiments on animals gold nanoparticles stop cancer due to atrophy of the blood vessels of the tumor. However, human trials have not yet been conducted.
