A methodology-based molecularly imprinted polymer (MIP) was proposed to separate epigallocatechin gallate (EGCG) from natural plant extracts. A molecular crowding agent was introduced to improve the affinity and recognizing ability of EGCG in the preparation of an MIP monolith. Acrylamide was used as the functional monomer, and ethylene glycol dimethacrylate was the crosslinking monomer, using a solution...
In this study, a simple method for analysis of nonderivatized sarcosine was developed by gas chromatography. It is based on solid-phase microextraction of sarcosine on a novel synthesized solid-phase microextraction (SPME) fiber. A monolithic SPME fiber was fabricated based on a molecularly imprinted polymer that could be coupled with gas chromatography for extraction and determination of sarcosine...
