A three-dimensional conductive molecularly imprinted electrochemical sensor based on MOF derived porous carbon/carbon nanotubes composites and prussian blue nanocubes mediated amplification for chiral analysis of cysteine enantiomers

Hierarchical porous MXene/amino carbon nanotubes-based molecular imprinting sensor for highly sensitive and selective sensing of fisetin

“…In the MIP synthesis process, a molecular recognition site with specificity in shape and size to the template molecules is generated [26]. Compared to non-conductive polymers, conducting polymers were considered as one of the best candidates for the synthesis of MIPs for J o u r n a l P r e -p r o o f selective recognition [27]. Among the conducting polymers, polypyrrole (ppy) is widely used in molecular imprinting sensors because of its advantages such as high electrical conductivity, convenient synthesis, environment-friendly and good catalytic performance [28][29][30].…”

Controlling the morphology of metal–organic frameworks and porous carbon materials: metal oxides as primary architecture-directing agents

“…A molecularly imprinted sensor was presented by Ma and coworkers. 553 On a glassy carbon electrode, carbon nanotubes and MOF-5 derived carbon were deposited. After cleaning, pyrrole was electropolymerized on the carbon surface in the presence of cysteine to obtain molecular imprinting for the cysteine molecule.…”

Carbon Nanomaterials Embedded in Conductive Polymers: A State of the Art

“…CNT-modified electrodes have been widely used for the detection of biomolecules due to their large active surface area, high conductivity, fast electron transfer kinetics and biocompatibility. They have also been used to provide chemical and electrochemical stability to the overall sensor [ 40 , 311 ]. Furthermore, CNTs are useful for the detection of neurotransmitters because the CNTs enhance the sensitivity and selectivity and have electrocatalytic effects, making them ideal biological sensors [ 312 ].…”

“…Since then, many studies have regarded this polymer, enunciating its stability in air, high conductivity and the ease of obtaining it [ 31 , 32 , 33 , 34 , 35 ]. Nowadays PPy is used in many fields, including in solar cells, biomedical applications, and energy storage, but its two main applications are in electronic devices and sensors [ 36 , 37 , 38 , 39 , 40 ]. The physical aspects of PPy are variable depending on the synthetic route used to obtain it and the final application; films, nanospheres, and nanowires are some examples of the possible final structures of PPy [ 32 ].…”
