Japanese scientists have developed a device that they say detects most kinds of cancer from a drop of blood in only three minutes.

The device uses a biochip, a sensor comprising multiple tiny test sites. It functions by attracting a faintly luminous substance found in cancer patients, even when the cancer is at a very early stage.

Known as Proteo, the chip is the result of collaboration between Kobe-based medical device manufacturer My Tech Inc. and researchers from Showa University.
