Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system ...

In future, blood samples may be taken by an autonomous robot rather than a healthcare professional – if Dutch developer Vitestro can get its prototype approved for marketing. Vitestro's blood ...

Other companies are currently developing blood tests based on a single drop, but Snyder envisions his being conducted more regularly at home, rather than during an occasional doctor's visit.

By combining terahertz radiation and optoacoustic detection, they created a non-invasive system that tracks sodium in real-time, even through the skin. The approach bypasses traditional barriers, such ...
