A research team at Binghamton University has developed a paper-based biosensor that monitors glucose levels through sweat analysis, potentially offering an alternative to finger-stick blood tests used by millions with diabetes. The innovative system, detailed in Microsystems & Nanoengineering journal, uses Bacillus subtilis bacterial spores that respond to glucose in potassium-rich bodily fluids. The power generated by this bacterial reaction indicates glucose levels. Professor Seokheun “Sean” Choi, who led the research with Assistant Professor Anwar Elhadad and PhD student Yang “Lexi” Gao, explains a key advantage: “The problem with using enzymes is that they denature and deactivate. You need to … Continue reading Paper-Based Sweat Sensor: A Non-Invasive Glucose Monitoring Breakthrough
