DNA-Functionalized Covalent Organic Framework for Colorimetric Detection and Adsorption Removal of Uranyl Ions.
Inspired by the modulatable nanozymatic activity of covalent organic frameworks (COFs) by single-stranded DNA (ssDNA), herein, we developed a versatile platform for sensitive/specific colorimetric detection and efficient adsorption of UO22+ based on DNA aptamer-functionalized COFs. Three COFs with varying alkyne conten...
