Novel ways to measure glucose levels without drawing blood

A recent study affiliated with UNIST has reported a new route for measuring blood sugar levels (BGLs) without drawing blood. This is a revolutionary, non-invasive technique for testing blood glucose levels, using electromagnetic (EM)-wave-based glucose sensor inserted under the skin. Their findings have attracted much attention, puscifer v is for viagra lyrics as the method eliminates the need for patients with diabetes to repeatedly prick their fingers with a glucose meter.

This breakthrough has been led by Professor Franklin Bien and his research team in the Department of Electrical Engineering at UNIST.

In this study, the research team proposed an electromagnetic-based sensor that can be subcutaneously implanted and is capable of tracking minute changes in dielectric permittivity owing to changes in BGLs. The proposed sensor, which is about one-fifth the size of a cotton swab, can measure changes in glucose concentrations in interstitial fluid (ISF), the liquid that fills spaces between cells.

“[Our] present work is an effort for the realization of an implantable electromagnetic-based sensor, which can be an alternate to an enzyme-based or optical-based glucose sensor,” noted the research team. “The proposed implantable sensor has not only overcome the disadvantages of the existing continuous glucose monitoring systems (CGMS), such as short lifespan, but has also enhanced the blood glucose prediction accuracy.”

Diabetes can be diagnosed if fasting blood glucose levels are 126 mg/dL or higher. A normal fasting glucose test result is lower than 100 mg/dL. One of the main aims of diabetes treatment is to keep blood glucose levels within a specified target range. More than 400 million people worldwide are living with diabetes and they still suffer while pricking their fingers multiple times a day to check their blood glucose levels.

Various methods alternate to the finger-pricking method have been extensively studied for blood glucose detection, such as enzyme-based or optical-based glucose sensor. Yet, they still have issues in terms of long lifetime, portability, and accuracy.

In this study, the research team introduced semi-permanent and continuous blood sugar management with low maintenance costs and without the pain caused by blood collection, enabling patients to enjoy quality life through proper treatment and management of diabetes. This is expected to increase the use of CGMS, which currently accounts for only 5% of active treatments.

The research team also performed both the intravenous glucose tolerance test (IVGTT) and oral glucose tolerance test (OGTT) with the sensor implanted in swine and beagles in a controlled environment. The results of initial proof-of-concept in vivo experiment showed promising correlation between BGL and sensor frequency response, according to the research team.

“Our proposed sensor and system are indeed in the early stage of development,” noted the research team. “Despite that, the proof-of-concept in vivo results show promising correlation between BGL and sensor frequency response. Indeed, the sensor shows the ability to track BGL trend.”

“For actual sensor implantation we must consider bio compatible packaging and foreign body reactions (FBR) for long term applications. In addition, improved sensor interface system is under development,” added the research team.

Their findings have been published in Scientific Reports.
