Molecularly imprinted ratiometric electrochemical sensor based on carbon nanotubes/cuprous oxide nanoparticles/titanium carbide MXene composite for diethylstilbestrol detection

MXene-Carbon Nanotube Composites: Properties and Applications

“…Despite the importance of synthesis conditions and functionalization processes, the optimization of reaction and experimental conditions is also vital to obtain high yields and improved results [ 83 ]. Xia et al [ 84 ] reported the design of molecularly imprinted polymer film through the electropolymerization of 1 H-pyrrole-3-carboxylicacid in the presence of diethylstilbestrol on CNTs/Cu 2 O nanoparticles/MXene (Ti 3 C 2 T x )-modified electrodes. The application of MXenes with accordion-like structures provided suitable electrical conductivity and enabled the immobilization of Cu 2 O nanoparticles.…”

“…The application of MXenes with accordion-like structures provided suitable electrical conductivity and enabled the immobilization of Cu 2 O nanoparticles. On the other hand, CNTs were deployed for improving the sensitivity of these electrochemical sensors with a wide linear response range (0.01–70 μM) and an LOD of 6 nM, providing suitable sensors with good stability for the reliable detection of diethylstilbestrol (a nonsteroidal estrogen medication) [ 84 ].…”

Endocrine disrupting chemicals in water and recent advances on their detection using electrochemical biosensors

“…112,152 As a novel planar material, MXene has been applied to support electrodes because of its large specific surface area, high electron mobility, and hydrophilic nature. 113,173 Electrode-supporting substances that contain functional ends are also frequently involved to present binding sites for biorecognition components. Instead of pristine graphene, graphene oxide (GO) is often employed to bind to other electrode additions such as ionic liquids (ILs), 153 3-aminopropyltriethoxysilane (APTES), 158 and metal nanoparticles, 184 relying on its abundant oxygen-containing functional groups.…”

MXene-modified molecularly imprinted polymers as an artificial bio-recognition platform for efficient electrochemical sensing: progress and perspectives

“…91 The incorporation of the MXene structure also facilitates the immobilization of nanomaterials and the fabricated MXMIEC shows excellent results. 92,93 Some of the electrochemical studies employing MXene-MIP composites are discussed. For the detection of fisetin, Ma et al developed an electrochemical sensor based on the negatively charged MXene, positively charged amino carbon nanotube composites, and MIPs.…”
