> So, coating the sensor’s “drum” head with concanavalin A, a bean protein with a strong affinity for sugar molecules, produced a glucose sensor That sounds like a one-off solution that lasts a few days to a few weeks, and then another implant is needed. I don’t think the proteins at the sensor surface can be recycled during use.
