London, November 29 (IANS) Researchers have devised a new nano tool that could become a new way to extract blood samples to get information about cancer, according to a study released Wednesday by the University of Manchester.
Minimally invasive blood tests have the potential to detect and monitor potentially life-threatening diseases such as cancer. But markers released into the bloodstream in response to an illness are often hard to detect because they are too small and in short supply, the Xinhua news agency reported.
The study, led by researchers at the University of Manchester, has shown that small molecules – particularly proteins – adhere to nanoparticles in the bloodstream of cancer patients. The collection of nanoparticles in the blood can then allow the analysis of sticky molecules, some of which are released by the growing cancer.
"We want to amplify cancer signals in the blood that would otherwise be buried among all these other" molecular noises, "said Professor Kostas Kostarelos, author of the study, in Manchester.
"Our team hopes to discover biomolecule panels that can detect early signs of cancer, which will be used as a basis for developing new diagnostic tests," said Professor Kostarelos.
The study was published in the journal Advanced Materials.
