Does the sight of a needle raise your anxiety level? Don't worry, scientists have now developed a new device which they calim can reveal a person's vital blood information in real-time, simply by shining a light through the skin.
This optical instrument, is able to provide high-resolution images of blood coursing through a person's veins without the need for harsh fluorescent dyes.
The instrument which is no bigger than a breadbox, has been devised by a team at the Israel Institute of Technology. Researcher Lior Golan said, they have invented a new optical microscope that can see individual blood cells as they flow inside our body.
He noted that the portability of the device could also enable doctors in rural areas without easy access to medical labs to screen large populations for common blood disorders
