oxygen levels in the brain

Chinese scientists have made a tiny wireless tool that can keep track of oxygen levels deep inside the brain. This small probe, only about 300 microns wide, contains a special light and sensor, covered in a material that reacts to oxygen. The probe emits light that changes brightness based on oxygen levels, which is crucial for monitoring brain health. It responds quickly, within one second, by shining brightly if there’s not enough oxygen.

The scientists tested it on freely moving mice, successfully monitoring oxygen levels in different situations. This discovery could become a helpful tool for caring for people with conditions like epilepsy, brain tumors, stroke, or head injuries in the future. The research involved scientists from Tsinghua University and other Chinese institutions.
