Chinese scientists have developed a miniature probe that is wireless and dynamically tracks oxygen levels in the deep brain, providing a promising tool for brain disease monitoring. The implantable probe, about 300 microns in diameter, comprised a light-emitting diode and a photo detector. It is coated with a phosphorescent film highly sensitive to oxygen, according to the findings published in the journal Nature Photonics on Friday. The probe works by emitting phosphorescence and measuring the oxygen levels according to the light brightness, which would decrease with the rise of the oxygen partial pressure. A key indicator reflecting brain oxygen levels,…
