Scientists have designed a new nanotool that can do an in-depth analysis and allow for the identification of previously unknown molecules in blood. The new minimally invasive blood tests can potentially identify and observe life-threatening conditions like cancer.

The study demonstrates that small molecules — specifically proteins — stick to the nanoparticles while in the blood circulation of cancer patients. Collecting the nanoparticles from the blood supports in the analysis of the sticky molecules, some of which are released from growing cancer.

Says the study author Prof Kostas Kostarelos from Manchester: ‘Our team hopes to discover panels of biomolecules that can point to early warning signs of cancer, which will provide the basis for the development of new diagnostic tests.’
