“…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.…”

“…Applications of this approach facilitate the detection of a wide range of potential analytes including, but not limited to, small organic molecules [107][108][109][110][111][112][113][114][115][116][117][118][119][120][121][122] and ions. [123][124][125] Supplementary materials can be added to the paste, boosting the conductivity of the composite and enhancing the sensitive of the system, with common additives including carbon nanotubes [108,110,111,124,125] or platinum nanoparticles.

Offering high specificity and selectivity, molecularly imprinted polymers (MIPs) are synthetic polymeric affinity reagents that have become increasingly popular over the last couple of decades. Due to their long-term chemical and physical stability and low production cost, they have become an increasingly popular choice of receptor in the realm of sense. MIPs have therefore been associated with the detection of small molecules, proteins, cells, and pathogens, proving a highly robust and useful tool in the production of next-gen sensing platforms. This said, the development of these sensors pivots on one simple fact; these receptors have to be deposited onto a substrate for their desired application. The deposition of MIPs during sensor fabrication is therefore of great importance, with the field utilizing an array of mechanical and chemical deposition methods to achieve this. To this end, this review, therefore, sets aim at coalescing these different deposition approaches, classifying them, and outlining their utility when it comes to receptor design and integration. Thus, offering a knowledge base on current deposition methods, potential future approaches and analyzing where the MIP deposition field is tending toward.

“…Ce-IP-MWCNTs-CPE showed a linear response to Ce 3+ in the concentration range of 1.0 to 25 pM with a LOD of 10 pM, and this method has been successfully applied to the determination of trace amounts of Ce 3+ in drinking water and seawater. Again, Alizadeh et al developed an inexpensive and simple potentiometric sensor based on CPE modified with IIP and MWCNTs to selectively recognize Cr 3+ [ 84 ]. The all-solid-state Cr 3+ -selective sensor was obtained by using IIP as an ionophore.…”

Heavy metal ions (HMIs) pose a serious threat to the environment and human body because they are toxic and non-biodegradable and widely exist in environmental ecosystems. It is necessary to develop a rapid, sensitive and convenient method for HMIs detection to provide a strong guarantee for ecology and human health. Ion-imprinted electrochemical sensors (IIECSs) based on nanomaterials have been regarded as an excellent technology because of the good selectivity, the advantages of fast detection speed, low cost, and portability. Electrode surfaces modified with nanomaterials can obtain excellent nano-effects, such as size effect, macroscopic quantum tunneling effect and surface effect, which greatly improve its surface area and conductivity, so as to improve the detection sensitivity and reduce the detection limit of the sensor. Hence, the present review focused on the fundamentals and the synthetic strategies of ion-imprinted polymers (IIPs) and IIECSs for HMIs detection, as well as the applications of various nanomaterials as modifiers and sensitizers in the construction of HMIIECSs and the influence on the sensing performance of the fabricated sensors. Finally, the potential challenges and outlook on the future development of the HMIIECSs technology were also highlighted. By means of the points presented in this review, we hope to provide some help in further developing the preparation methods of high-performance HMIIECSs and expanding their potential applications.
