Cancer Killing Nano-machine
Biomedical engineers at Cornell University (US) have developed a “cancer-killing machines” made up of sticky nanoparticles, to prevent cancer cells from spreading throughout the body. These are made by attaching two proteins, E-selectin and TRAIL, on the surface of nanoscale liposome or nano-particles.
E-selectin is an adhesive molecule that can bind to other cells. TRAIL is a therapeutic protein made by immune cells that can program cancer cells to die upon contact, a process called apoptosis (i.e., cell death). Together they make a tag-team effort: one protein to stick, one to kill.
These sticky nanoparticles are injected into blood stream which attaches themselves with the white blood cells (WBCs). As soon as sticky nanoparticles came in contact with cancel tumour cells which had broken off the main tumour and were trying to spread, it kills them. It thus prevent tumour from spreading into other organs or tissues. The test results are significant in human blood and mice.
The research team, which recently published its findings in Proceedings of the National Academy of Sciences, is led by biomedical engineer Michael King. This ground-breaking research could one day pave the way for eliminating 90 percent of cancer deaths.
