Working Towards an Implantable Glucose Sensor

An implantable sensor that allows diabetics to more effectively monitor their blood-sugar levels is a step closer to reality, thanks to Melissa Grunlan, associate professor in Texas A&M University's Department of Biomedical Engineering. Grunlan is developing a "self-cleaning" membrane that envelops an implanted glucose sensor, shielding it from the body's immune response that would otherwise render it nonfunctional.
