The FET’s closely packed, hexagonal, nanostructured network resulted from complimentary patterning techniques thathave the potential for low-cost fabrication.Their high sensitivity could also measure things such as pulse rate, oxygen levels, and other aspects of health monitoring that require precise control. Many are still managing with blood droplets on glucose strips, thenusing self-injection,” he said.Type 1 diabetes, formerly known as juvenile diabetes, can lead to serious health complications like retinopathy, blindness, neuropathy, kidney and cardiac disease, if the glucose level is not carefully controlled.This research builds on earlier work by Herman and other OSU engineers that developed a glucose sensor that could be wrapped around a catheter, such as one used to administer insulin from a pump..The sensor developed by the researchers from Oregon State University (OSU) in the US, uses a nanostructured transistor that can detect subtle glucose changes in physiological buffer solutions, such as the tear fluid in eyes.”We can monitor many compounds in tears and since the sensor is transparent, it doesn’t obstruct vision,” said Herman. Researchers in the OSU said the nanostructured transistor is specifically an amorphous indium gallium oxide field effect transistor (IGZO FET). “We have fully transparent sensors that are working,” said Greg Herman, professor at OSU. The sensor and pump would, in effect, act as an artificial pancreas.
The study appears in the journal Nanoscale. “A lot of type 1 diabetics dom not wear a pump. New York: Diabetes patients may soon be able to monitor their blood sugar with contact lenses – spelling an end to painful jabs – thanks to scientists who have developed a transparent sensor. The sensor could communicate with your phone to warn you if your glucose was high or low,” he said. The transparent FET sensors, might ultimately be used for cancer detection, by sensing characteristic biomarkers of cancer risk, he said. “We can integrate an array of sensors into the lens and also test for other things: Thin-wall Product Mould Manufacturers stress hormones, uric acid, pressure sensing for glaucoma, and things like that,” he said. Those techniques include colloidal nanolithography and electrohydrodynamic printing, or e-jet, which is somewhat like an inkjet printer that creates much finer drop sizes and works with biological materials instead of ink.The sensors they fabricated using the IGZO FET will be able to transmit real-time glucose information to a wearable pump that delivers the hormones needed to regulate blood sugar: insulin and glucagon.Such sensors can detect subtle glucose changes in physiological buffer solutions, such as the tear fluid in eyes.”Even with the contact lens, someone could still manage their diabetes with self-injection
