Electrochemical sensors modified with ion-imprinted polymers for metal ion detection

Nanomaterials-Based Ion-Imprinted Electrochemical Sensors for Heavy Metal Ions Detection: A Review

“…The thickness, hydrophobicity and permeability of IIPs prepared by this method can be artificially controlled and these IIPs are usually non-conductive, so conductive additives such as graphene or GO etc. are added to the pre-polymerized mixture [ 24 ]. The HMIIECSs prepared by this method presents simple and good recognition performance, but their IIMs are easy to fall off and their reproducibility is poor.…”

“…[ 23 ]. However, for IIPs, the functional monomers including MAA, acrylic acid (AA), acrylamide (AM), 4-vinylpyridine (4-VP), etc., are divided into two categories that one with double bonds, and the other with functional groups such as amino groups and hydroxyl groups, which can chelate with metal ions [ 24 ]. IIPs have some benefits similar to those of MIPs, including high chemical stability, ease of preparation, low cost, predetermined recognition ability, repeatability, and adaptability to harsh environment, so as to improve the selectivity and sensitivity of electrochemical sensors (ECSs) [ 25 ].…”

A benzothiazole-based new fluorogenic chemosensor for the detection of CN− and its real-time application in environmental water samples and living cells

“…Ions have a variety of important functions in chemical and biological processes. [1][2][3][4][5][6][7][8][9] Among them, many anions are naturally occurring, and they have signicant roles in essential disciplines, including life science, chemistry, medicine, catalysis, and the environment. [10][11][12][13][14] To this end, for the past few years, anion recognition has become an area of growing concern in the eld of environmental and biological sciences.…”

Carbon Dots‐Decorated g‐C3N4 as Peroxidase Nanozyme for Colorimetric Detection of Cr(VI) in Aqueous Medium

“…A variety of techniques, including atomic absorption, [28] emission, [29] and mass spectroscopies, [30] electrochemical, [31][32][33] have been reported for the effective detection of heavy metal ions. Although extremely efficient in detecting heavy metal ions, these methods require a lot of time and rely heavily on pricey, sophisticated equipment.…”
