Self color-changing ordered mesoporous ceria for reagent-free colorimetric biosensing

A reagent-free colorimetric detection method using mesoporous cerium oxide with a large pore size trapping an oxidative enzyme has been developed and glucose is sensitively detected with a limit of detection of 10 μM by supporting glucose oxidase on mesoporous cerium oxide. A reagent-free colorimetr...
