While in Russia to master the new technology remove malignant tumors "CyberKnife" In Europe we have developed a new invention that allows you to clean the blood from human cancer cells using sound. Probably, it would also help to detect cancer cells that have spread in the body, said New Scientist .
After contact with cancer cells in the blood occurs metastasis That is, the spread of tumor cells of the body cavity or blood and lymphatic vessels. Molecular markers are used as susceptors of cancer cells change their structure, making them unsuitable for research and analysis.
To solve this problem, Itziar Gonzalez Madrid Institute of Acoustics and colleagues have suggested another way. A small vibrating cylinder, wherein the flow of blood samples. Stagnant water, creates a vibration, rejects the cells depending on their size.
Normal cells blood cancer is usually smaller, so the device allocates them to different parts. This process does not alter the cell structure, which gives the opportunity to explore it.
Test the device showed that he was able to correctly distinguish between cancer cells with 70% probability. The improved version will allow to correctly distinguish cancer cells with 95% probability, due to a prolonged exposure to sound waves.
