Using Additive Manufacturing To Print Glucose Sensors To Manage Diabetes

Engineers have developed a technique similar to inkjet printing that hey used to fabricate a new glucose sensor for the management of diabetes. The researchers claim the new system is more precise and efficient, and less costly, than current manufacturing methods and could lead to an artificial pancreas with a single point of bodily entry.

The technology, developed at Oregon State University (OSU) under the supervision of Gregory Herman, uses an electrohydrodynamic jet (e-jet) printer loaded with “ink” made from glucose oxidase, bovine serum albumin, and glutaraldehyde (as a cross-linking agent). The printer deposits the sensor onto a plastic substrate that can be wrapped around a catheter.

In a study published in The Electrochemical Society Journal of Solid State Science and Technology, the researcher team concluded, “the flexible sensor design developed in these studies can ultimately be used within a closed loop artificial pancreas control system thereby reducing the number of components in such a system.” … (read more)
