Schematic of microfluidic magnetic solid-phase extraction-colorimetric method for separating and detecting SMX based on Fe3O4@PCN-222@MIP: (A) Synthesis process of Fe3O4@PCN-222@MIP; (B) Schematic of MIP binding and adsorption-desorption of Fe3O4@PCN-222@

Caption

This illustration depicts the design of a smart magnetic composite material and its integration into a microfluidic chip for the rapid detection of the antibiotic sulfamethoxazole (SMX). The process encompasses the synthesis of the functional material, its specific capture of SMX molecules, and the on-chip magnetic separation and colorimetric detection, enabling a streamlined, elution-free workflow.
