At present, diabetes has become one of the most serious public health problems in the world. For patients with type 1 and part 2 diabetes, long-term injection of insulin combined with blood glucose monitoring is an essential treatment. However, such treatments not only cause great pain to the patient, but may also cause complications such as hypoglycemia. In 2015, the technology of “smart insulin patch†first proposed by Chinese scientist Professor Gu Yu brought new hopes for improving diabetes treatment. This technology, which combines blood glucose monitoring and insulin injection, was published in PNAS magazine in June of the same year and was selected as the "Top 10 images of 2015" in Science. Smart insulin patch Specifically, "smart insulin patches" consist of hundreds of microneedles. Insulin and glucose sensors are stored in the microneedles. When the blood sugar level is too high, the micro-needle will automatically release insulin and exert blood sugar lowering effect. According to Prof. Gu Yu, “smart patch†is actually a “bionic designâ€, which aims to simulate the rapid response of vesicles stored in insulin in normal islet cells with changes in blood glucose, and can effectively prevent hypoglycemia. The entire “patch†can also be customized to the patient's weight and insulin sensitivity. In addition, the “patch†also uses micro-needle painless treatment, which can greatly improve the quality of life of diabetic patients.
