A flexible dual-readout sensor based on Mn-doped CeO2 Nanozymes for selective nitrite monitoring in pickled vegetables
{{output}}
A rapid and flexible visual sensing patch was developed for nitrite detection by integrating Mn-doped CeO2 with a polyacrylamide (PAM) hydrogel. The incorporation of Mn into the CeO2 lattice significantly enhances oxidase-like activity by facilitating electron... ...
