Scientists in Saudi Arabia have developed a prototype sensor that could make checking blood sugar levels much more convenient for diabetics. By analyzing glucose in saliva instead of blood, it aims to revolutionize how diabetes is managed.
The sensor uses thin-film transistor technology to accurately detect even very low levels of glucose in saliva. Researchers tested it on real human samples, and it produced results within one minute for a wide range of glucose concentrations seen in diabetes patients.
Best of all, the sensor ignores other molecules in saliva, like sugar, and can still work well after two weeks. This means consistent, reliable readings without painful finger pricks. With more testing, it hopes to replace traditional blood glucose monitors.
The team plans portable arrays combining this sensor with others to simultaneously check multiple health markers from a single saliva sample. This could be combined with smartphones for an all-in-one diabetes management solution.
Their research offers hope that managing blood sugar could become easier, faster, and less painful through this innovative saliva-based approach. With further development, it may revolutionize how diabetics monitor their condition day-to-day.
