Molecularly imprinted polymer based potentiometric sensor for the determination of 1-hexyl-3-methylimidazolium cation in aqueous solution

Potentiometric Sensing

“…MIPs have shown to be useful in different analytical applications and became recently rather popular as recognition elements incorporated in the polymer membranes of ISE. MIPs were used for the potentiometric detection of the insecticide dinotefuran, 1-hexyl-3-methylimidazolium, acetylcholine, lactic acid, 2-naphthoic acid, taurine, bisphenol S, and bisphenol AF . Unfortunately, it appears that the authors sometimes overestimate the sensing power of MIP materials and tend to disregard some fundamental principles of potentiometry.…”

“…Thus, one is left to wonder about the origin of the observed response. Zhuo and co-workers reported on a potentiometric sensor based on MIPs for determination of the cationic 1-hexyl-3-methylimidazolium 93. The authors prepared the MIP material using MAA and EGDMA as the functional monomers and cross-linking agent.…”

Recent developments in electrochemical detection of illicit drugs in diverse matrices

“…Until now, the amount of immobilization protocols is still limited. For potentiometric sensors, selective membranes were embedded by dispersing MIPs in a plasticized polyvinyl chloride (PVC) matrix or carbon paste (Smolinska-Kempisty et al, 2017;Zhuo et al, 2016). Another option is sol-gel based immobilization.…”
