A high performance potentiometric sensor for lactic acid determination based on molecularly imprinted polymer/MWCNTs/PVC nanocomposite film covered carbon rod electrode

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.…”

“…Alizadeh et al introduced a MIP-based sensor for lactic acid sensing in dairy products . MIP was synthesized using allyl amine and EGDMA as functional monomer and cross-linker.…”

Determination of cesium ions in environmental water samples with a magnetic multi-walled carbon nanotube imprinted potentiometric sensor

“…Multiwalled carbon nanotubes (MWCNTs) and Fe 3 O 4 nanoparticles (NPs) have also been employed in sensors as modication materials due to their large surface area, good stability, conductivity and electron transfer, which can improve the analytical sensitivity of the electrochemical sensor. [25][26][27][28][29] The integration of MWCNTs and Fe 3 O 4 NPs is expected to provide a synergistic effect in electrochemical sensor construction.…”

Novel Zn‐Fe LDH/MWCNTs and Graphene/MWCNTs Nanocomposites Based Potentiometric Sensors for Benzydamine Determination in Biological Fluids and Real Water Samples

“…The selectivity behavior is obviously one of the most crucial important parameters of the potentiometric sensor, reflecting its capability to discriminate analyte ion from other interfering species present in solution [77]. In the late 1990s, researchers found that the conventional methods of evaluation such as the separate solution and matched potential methods [78,79] were biased by the consequences of the ion-exchange processes at the membrane/solution interface as well as trans-membrane Table 2.…”
