Smart insulin patch will monitor glucose levels, will make life of diabetics easier

Researchers have created a coin-shaped smart patch, which will monitor glucose levels in the body of diabetes patients and also ensure the delivery of insulin as needed. According to a study published in the journal Nature Biomedical Engineering, this patch of adhesive in the body is equivalent to a coin in size. It is also easy to make and can be used once a day.

Researchers at North Carolina University (UNC) in the United States said, 'Hormones in our pancreas maintain insulin levels naturally in the body by producing insulin. Glucose is one such source of energy that we mainly get from fruits.

Patients with type-1 diabetes are not able to make insulin automatically, whereas patients with type-2 diabetes are not able to efficiently use the insulin produced in the pancreas. The number of patients of both these types of diabetes in the world is more than 40 crores.

"Our main goal is to improve the quality of life of diabetes patients and improve their health," said Jane Gu, a former UNC professor and co-author of the study. He said that the new smart patch removes the need to continuously check a person's blood sugar and inject insulin when needed. In other words, it is capable of replicating the regulatory function of the pancreas and is also easy to use.

This patch, the researchers said, monitors blood sugar and glucose levels in the body and contains pre-loaded insulin doses in very small micronidils, which are less than a millimeter in length. This is the delivery of the drug quickly after the level of low blood sugar (blood sugar) reaches a certain limit. When blood sugar levels return to normal, the delivery of the drug through the patch also automatically reduces and the drug delivery stops after a time.

Researchers said one of the advantages of this is that a person can also avoid the risk of taking insulin overdose. Glucose levels are reduced by taking excessive amounts of insulin and the person is at risk of seizures as well as coma. Co-author of this study from UNC, John Buse, said, 'This smart insulin patch will revolutionize the monitoring of a diabetic patient if proven safe and effective in human trials.

The study states that the microneedles used in the patch are made from a glucose-sensing polymer, which is surrounded by insulin. Once the patch is applied to the skin, its needle penetrates under the skin. It can also feel blood sugar levels. According to the researchers, the polymer automatically starts releasing insulin whenever the glucose level rises.

Robert Langer, co-author of this study from the Massachusetts Institute of Technology in the US, said, 'I am delighted that our team will soon bring this smart insulin patch one step closer to reality and we hope that in the future it will bring about diabetes Nothing will be less than a living for patients.
