Are thin-film/adhesive patch glucose monitors the thing this year? University of California San Diego Health (UCSD Health) opened earlier this month a clinical trial of their self-adhesive ‘tattoo’ type glucose monitor. This monitor measures the glucose present in perspiration through two electrodes embedded in the thin adhesive film that apply a small amount of electrical current to make glucose molecules in the skin rise. The clinical trial sampling people with Types 1 and 2 diabetes ages 18-60 with fasting plasma glucose (FPG) > 126 mg/dL, or hemoglobin A1c (HbA1c) > 6.5%. Those in the trial will be comparing their readings from the thin film monitor with a standard glucometer through June 2019. Patients wearing the sensors will receive a minimum of two doses of pilocarpine gel to induce sweat, at fasting and at time points ranging between 15 to 200 minutes post meal. Neither the article nor the clinical trial explain the reading process.
In a Mobihealthnews interview with Patrick Mercier, codirector of UCSD’s Center for Wearable Sensors, the sensor can be produced for under $1, comparable to a blood glucose test strip.
Tattoo-type sensors and strips made the news about two-three years ago in their early stages of development and now are resurfacing with both trials and investment. Sano received $6 million from Fitbit for its combination of sensor and mobile app. The University of Bath has designed a multi-sensor patch that doesn’t need gel to raise a sweat; it measures interstitial fluid located between cells within the body-hair follicles [TTA 24 Apr]. We are rapidly moving towards less-invasive monitoring systems and better diabetes management.

has developed a graphene-based blood glucose sensor that if successfully commercialized could eliminate the diabetic finger-stick. The sensor patch measures the interstitial fluid located between cells within the body-hair follicles–each mini sensor measures an individual follicle, where glucose collects in tiny reservoirs. The sensor patch can monitor every 10-15 minutes for continuous measurement. At this developmental point, readings are not sent to a smartphone. The researchers are focusing on optimizing the number of sensors in the patch, demonstrating successful use over 24 hours, and clinical trials. The University of Bath study with researchers from their Centre for Graphene Science, Centre for Nanoscience & Nanotechnology, and the Department of Pharmacy & Pharmacology, was published in Nature Nanotechnology

A possible combination? Treating Type 2 diabetes usually requires medication to regulate insulin. Glucagon-like peptide-1 (GLP1) causes the pancreas to release insulin but has a short half-life. Researchers at Duke University have developed a way to bind GLP1 to a heat-sensitive elastin-like polypeptide which forms a gel-like depot that releases slowly into the body. In early tests with mice and monkeys, the ‘depot’ releases a constant rate of GLP1 for up to 14 days. The slower human metabolism means that this may be a feasible 14-30 day treatment–and translate to the controlled release of other medications. New Atlas
