Chemists have turned red blood cells into long lived sensors that could be put back into circulation to monitor the make up of patients’ blood in real time.
Many patients require monitoring of their blood, such as diabetics who must prick themselves with needles to elicit blood for determining their glucose levels. But extracting blood is both invasive and provides only a one-off measurement. At the American Chemical Society meeting in Philadelphia on Sunday, Xiaole Shao explained how her team have built sensors that may one day allow both non-invasive and long-term monitoring of crucial aspects of blood chemistry.
