Diabetes Research, utilising a graphene skin patch.
A skin patch is currently being tested that "senses" an individuals glucose levels and which corrects an elevated level of blood glucose by administering a calibrated dose of a drug. The Graphene 'atom thick' skin patch if successfully approved will mitigate the need for skin pricking in blood glucose management.
The system monitors sweat levels and is a monitoring and feedback therapy being researched by a collaborative team from the USA and Korea. The patch is stretchable, and monitors the glucose level, the programmed limits will solicit a process for administering the corrective drug Metformin by heating microneedles embedded in the skin.
Graphene is a nanomaterial which is one atom thick and is the focus of many innovations for tech wearing functionality. Wearable electronics are promising to revolutionise our world. In this instance the graphene is infused with gold nanoparticles to increase conductivity of the material.
The patch has an array of sensors that record not only glucose levels but also temperature, humidity and pH, these are used to ensure accurate interpretation of the result.
"... although the holy grail of diabetes management - a non-invasive feedback system combining glucose monitoring and responsive drug delivery - is not yet at hand, Kim and co-workers have certainly moved the field closer to this coveted prize." Prof. Richard Guy. Bath University.
