Boosting Enzyme Efficiency with ZIF-90 for Better Glucose Detection

In the world of biosensing, enzymes often struggle with stability and efficiency. They can easily break down, and the substances they work on may decompose before the job is done. Scientists have found a clever way to fix this by trapping two essential enzymes, glucose oxidase and horseradish peroxidase (GOx & HRP), inside a special structure called ZIF-90. This structure keeps the enzymes in their best shape, making them work better even in tough conditions. By doing this, the scientists reduced the risk of enzymes breaking down and improved the sensitivity of their biosensor.When tested with complex biological samples, like serum, the sensor worked well, giving stable and trustworthy glucose readings. It could detect glucose levels from zero to 2. 5 micrograms per milliliter with impressive precision. Even better, the team created a simple paper-based sensor that uses a smartphone to visually detect blood glucose levels.
