Diabetes, a metabolism disorder has become one of the most common health threats in the world today.
New in the fight against this disease is a patch which measures the amount of sugar present in a diabetic’s sweat.
They could put an end to the quite painful constant finger prick tests which is the conventional go-to for checking a diabetic’s sugar level.
Hyunjae Lee, author of the study at Seoul National University, said: “Diabetics are reluctant to monitor their blood glucose levels because of the painful blood-gathering process.
“We highly focused on a noninvasive monitoring and therapy system for diabetics.”
The patch has tiny needles that are filled with drugs. If the patch reads a high sugar level, the tiny needles inject Metformin into the blood stream. Metformin is the drug usually prescribed to sufferers of type 2 diabetes which is mostly propagated by obesity.
The wrist patch is made of graphene, a thin but strong material, and gold.
The patch has been tried on both mice and humans. When tried on some elderly men, it read their blood sugar levels correctly. When tested on diabetic mice, it pumped out the necessary amount of Metformin to keep their blood sugar level regulated.
The wrist patch proves to be more effective than the occasional needle jabs. The needles in the patch are too tiny to hit the nerve endings, hence causing way less pain than the usual injections. Also, the patch could be used to dispense insulin– another diabetes treatment into the bloodstream.
The device which was created in the Institute for Basic Science in South Korea is still in its prototype stage and would need to undergo modifications before it is made available to the public.
The research was published in the journal Nature Nanotechnology.
