Nanotechnology may prevent cancer from spreading by using sticky nanoparticles. Researchers of Cornell University (US) have designed these sticky nanoparticles. These are made by attaching Trail protein and other proteins to the nanoparticles.
As per the results of earlier trial tests, Trail protein has the ability to kill cancer cells. These sticky nanoparticles are injected into blood stream which attaches themselves with the white blood cells. Tests revealed that as soon as sticky nanoparticles came in contact of cancel tumor cells which had broken off the main tumour and were trying to spread, it kills them. It thus prevent tumour from spreading into other regions. The test results are significant in human blood and mice.
The lead researcher Professor Michael King suggested that sticky nanoparticles should be used before surgery or radiotherapy. This move would help in removing tumour cells from the main tumour.
