Abstract

Complexing with adenosine-5′-monophosphate (AMP) was proven to be a facile way to enhance the oxidase-mimicking activity of Ce⁴⁺, and enabled nanoenzyme recovery and reuse. Additionally, the oxidase-mimicking activity of AMP-Ce⁴⁺ infinite coordination polymers (ICPs) could be specifically inhibited by Fe²⁺. Based on this finding, we developed a simple and highly selective colorimetric assay to detect Fe²⁺.
