Super-sensitive tests
30 July 2012
Scientists have developed an ultra-sensitive test that should enable them to detect signs of a disease in its earliest stages, in research published in the journal Nature Materials on 25 May.
The scientists, from Imperial and the Universidade de Vigo, Spain, have created a test to detect particular molecules, or biomarkers, that indicate the presence of disease, even when these are in very low concentrations. Tests are already available for some diseases that look for biomarkers using biological sensors, or biosensors. However, existing biosensors become less sensitive and predictable at detecting biomarkers in very low concentrations, such as when a disease is in its early stages.
