Molecularly imprinted core–shell hybrid microspheres for the selective extraction of vanillin

Abstract

Molecularly imprinted polymers (MIPs) with a core–shell structure for efficient, reliable, and selective extraction of vanillin <italic>via</italic> solid-phase extraction (SPE) and incubation methods were developed using a sol–gel process based on (3-aminopropyl)triethoxysilane (APTES) as the functional monomer, tetraethoxysilane (TEOS) as the cross-linker, and vanillin as the template.
