Taiwan professor developing non-invasive blood glucose monitor (2021/01/13)
People with diabetes have to keep track of their blood sugar levels, usually by pricking their finger with a needle. But what if there were a way to monitor glucose, blood-free? A professor at National Taiwan Normal University has built a breath detector that can assess the level of blood glucose in the body by measuring the amount of carbon dioxide. The machine is still in an early stage of development, but it holds out promise for a painless way to manage diabetes.
Blow into the tube, and in just three minutes, the machine is able to detect the content of carbon dioxide and residual oxygen in the body, which can be used to estimate blood sugar levels. This is not an alcohol breathalyzer, but a non-invasive blood glucose monitor. It works because there's a correlation between a carbon dioxide concentration and blood sugar concentration in the blood.

National Taiwan Normal University Analytical Chemistry professor
If someone is healthy, about an hour to two hours after eating, their carbon dioxide level will return to a normal state. The carbon dioxide content will drop, and the blood sugar should also drop. If the carbon dioxide does not drop, it means there may be something wrong. We have tested patients using a regular glucose monitoring device and with this method, it's pretty accurate.
This detector was developed over the course of 10 years by Lin Cheng-huang, an analytical chemistry professor at NTNU. His team hopes the device can eventually be used to screen people at risk of diabetes. It can also be developed into an at-home test kit for diabetics, or into a screening system for other diseases.

There are actually many lung diseases related to a high concentration of carbon dioxide.
Dr. Toshio Kasia
National Taiwan University visiting professor
Because respiration is a very essential chemical reaction. It's called cellular respiration. Any cell consists of your body needs oxygen. By monitoring oxygen absorption and the emission of C02 that's a good indicator of your health, bodies, or activity of organs.
The developers have run tests on about a dozen people so far and are now looking to expand their trials to enhance the accuracy of the device.

全球獨創！ 呼氣就能測血糖高低
糖尿病患者要掌握自身血糖高低，通常要忍痛扎針，不過，台師大教授研發出呼氣偵測器，只要吹氣，透過測得二氧化碳的多少，就能評估體內血糖高低。這個機器目前仍在開發的早期階段，未來希望能讓糖尿病患者用無痛的方式，就可以監測血糖。
大口吹氣，這可不是要做酒測，而是測血糖。只要3分鐘，就能知道體內二氧化碳和殘氧的含量，藉此推測血糖高低。
[[台師大化學系教授 林震煌]]
"如果是正常的話，大概一個小時到兩個小時之後，應該回復到正常的狀態，二氧化碳會下降，血糖也應該下降，如果二氧化碳沒有下降的話，就表示可能有什麼問題， 我們有用簡易型的血糖機來做測試，是正確的"
台師大化學系教授林震煌耗費10年開發的偵測器，如果臨床試驗順利，將來就能讓糖尿病患者與潛在患者，在家中就可以得知血糖濃度變化。

"因為二氧化碳的增加，導致肺病的疾病其實很多種"
[[國立台灣大學化學系客座教授 竿井俊夫]]
"因為呼吸是非常重要的化學反應。這就是呼吸作用。人體所有的細胞都需要氧氣。監測氧氣的吸收和二氧化碳的排放，是了解自己身體或器官狀態，很好的方式"
到目前為止，開發團隊已經檢測10到20個人，未來將擴大檢測樣本數，提高偵測器的準確性。
