Hydrogel-based Biosensors

Hydrogel-based biosensors are devices that use a jelly-like material called hydrogel to detect biological substances, such as glucose or pathogens. The hydrogel can absorb fluids and contain special molecules that react with specific targets. When the target substance is present, it causes a change in the hydrogel’s properties—like color or electrical signals—that can be measured. These biosensors are flexible, biocompatible, and can provide quick, accurate diagnostics for medical, environmental, or food safety applications. They combine the sensitivity of biological detection with the versatility of hydrogels, making them valuable tools for real-time analysis.
