Description
Ruya Guo and co-authors forge a two-metal nanozyme that makes Salmonella in food glow blue at trace levels. Color tests using enzyme-like nanoparticles are fast, but plain particles catalyze weakly. Their design shells cerium oxide dots onto copper oxide cubes, forming a core-shell heterostructure.
The pairing stops the dots clumping, exposes abundant active sites, and, per computer models, builds an electric field at the seam that hurries electrons and grips the reaction fuel. The labeled test detected Salmonella down to twenty-six colony-forming units per millilitre, stayed specific against other germs, and worked in spiked food samples. The authors offer the recipe as a general route to hotter nanozymes for rapid food checks.
