Tiny biosensor to detect cancer
Scientists are developing a tiny biosensor to detect cancer proteins and potentially the bug that causes MRSA. It makes use of the same gyroscope technology as navigation systems and car airbags.
The aim is to incorporate it into a hand-held device for quick and easy analysis of tissue samples.
The European Union has awarded international researchers, led by the University of Newcastle, a 12m euro grant to refine the technology.
The vibrating disc is no bigger than a speck of dust. It is hoped it could enable doctors to diagnose and monitor common types of cancer, and to assess which is the most appropriate therapy.
The device would work by identifying cancer markers – proteins or other molecules produced by cancer cells.
These vary according to the type of cancer and are distinct from proteins produced by healthy cells.
