Researchers are developing a tiny silicon 'mirror', which will reflect light from a laser and enable doctors to detect any cancer markers in the bloodstream.
Scientists have created a porous silicon device, which will reflect light at the wavelengths through which it can pass through the skin.
The new device has layers of alternating high- and low-porosity, and, it is thought, will eventually break down into silicic acid in the blood.
|The silicon ‘mirror' could be used as a non-invasive alternative to current blood monitoring tests.|
Developer Roger Aston, of pSiMedica, of Malvern, Worcestershire, England, said, "Rather than having to go for regular blood tests, you could just drop by your doctor and get a quick, non-invasive check."
Stephen Mather, Head of Nuclear Medicine at St Bartholomew's Hospital, London, England, told the magazine, "It sounds a nice idea, but they'll have to show they can get a good signal out of this when it starts binding to the markers. It'll also be interesting to see if they can make this more sensitive than the current blood tests."
