“…Propranolol (1‐isopropylamino‐3‐(1‐naphthoxy)‐2‐propanol) is known to be irreversibly oxidised on the modified GCE in a potential range from 1–2 V, with the transfer of two electrons . The majority of the publications attribute the oxidation peak to the hydroxyl group directly bonded to the chiral center , whereas a few papers assign it to the secondary amine . For some electrodes, the voltammograms of the propranolol enantiomers differ among themselves .…”

“…The majority of the publications attribute the oxidation peak to the hydroxyl group directly bonded to the chiral center , whereas a few papers assign it to the secondary amine . For some electrodes, the voltammograms of the propranolol enantiomers differ among themselves . On the bare (Figure c) and PAP‐modified GCE (Figure d) against a background of 0.1 M H 2 SO 4 , the enantiomers of propranolol are oxidised in the investigated potential range with the formation of the corresponding peaks.…”

An enantioselective voltammetric sensory system based on glassy carbon electrodes modified by polyarylenephthalide composites of melamine and cyanuric acid using chemometric method principal component analysis for the recognition of propranolol enantiomers was developed. It is shown that glassy carbon electrodes modified by polyarylenephthalide composites of melamine and cyanuric acid exhibit the properties of enantioselective sensors. The molecular dynamics simulations of the interaction processes of propranolol enantiomers with polyarylenephthalide composites of melamine and cyanuric acid show that the differences between the voltammograms of propranolol enantiomers on such electrodes are due to differences in the energy of hydrogen bonds formation between enantiomeric molecules and supramolecules of melamine and cyanuric acid. This is reflected not only in the characteristics and shape of the voltammograms, but also in the sensitivity of the electrodes, with respect to the propranolol enantiomers. The possibilities of the sensory system for express recognition of R‐ and S‐propranolol are considered. The recognition of these enantiomers by the registered voltammograms on two glassy carbon electrodes modified by polyarylenephthalide composites of melamine and cyanuric acid allows to increase significantly the percentage of correctly recognised samples in comparison with the registration of voltammograms on only one electrode.

“…Compared with R-PRO, S-RPO has much higher affinity with ctDNA. [108] Using an l/d-cysteine modified gold electrode, Yang et al developed an electrochemical chiral sensing strategy to recognize carnitine enantiomers. [109] Chen et al reported an electrochemical enantioselective sensor based on a quasi-chiral MWCNT/ionic liquid nanocomposite and used this sensor to achieve enantiomeric recognition of propranolol.…”

nanostructures, both static and dynamic. [8] According to the material composition and underlying mechanisms of chiral nanostructures, Chen and co-workers summarized their preparation methods and properties. [10] Nam and co-workers summarized the chiral assemblies of plasmonic nanostructures enabled by biomolecules (amino acids, peptides, DNA, etc.). [11] After paying great attention to the preparation, characterization, and optical properties of chiral materials, researchers are now focusing on their potential applications, [12] such as optical devices, [13] chiral catalysis, [14] chiral memory, [15] chiral detection, [16] biolabeling, [17] chiral recognition and separation, [18] and others. [19] This progress report will focus on the bioapplications of chiral materials. Herein, first the general design principles of chirality-based biosensors will be introduced. Subsequently, the focus will shift to chiral sensors based on chiral semiconductor nanoparticles, followed by a description of chiral metal-nanoparticle-based probes in Section 4. Next, a variety of chiral sensors using chiral nanoassemblies will be discussed in Section 5. Sections 6 and 7 will review probes based on chiral meta-materials and metalorganic frameworks (MOFs) respectively. Biosensors based on other chiral materials will also be summarized. Finally, a brief conclusion and a perspective on the future development of chiral-material-based sensors will be provided.

“…Using the irreversible and adsorption-controlled oxidation process of the estrogen onto the three-bilayer CTS@MWCNT/FTO, it was possible to determine it by SWV (LOD = 0.09 µmol L −1 ) without significant effect of the most common interfering compounds present in human urine (urea, uric, and ascorbic acids, glucose, NaCl, KCl, and NH 4 Cl). Chen et al [33] used a nanocomposite based on MWCNT and 1-octyl-3-methyl-imidazolium hexa-fluorophosphate ionic liquid (IL) to modify a GCE, to develop a chiral electrochemical sensor for the enantiomeric recognition of propranolol, using the linear sweep voltammetry (LSV) technique. The authors did not present a LOD but declared the success of the proposed method to evaluate the enantiomeric purity of reagents and wastewater treatment efficiency.…”

Multi-walled carbon nanotubes (MWCNT) have provided unprecedented advances in the design of electrochemical sensors. They are composed by sp2 carbon units oriented as multiple concentric tubes of rolled-up graphene, and present remarkable active surface area, chemical inertness, high strength, and low charge-transfer resistance in both aqueous and non-aqueous solutions. MWCNT are very versatile and have been boosting the development of a new generation of electrochemical sensors with application in medicine, pharmacology, food industry, forensic chemistry, and environmental fields. This work highlights the most important synthesis methods and relevant electrochemical properties of MWCNT for the construction of electrochemical sensors, and the numerous configurations and successful applications of these devices. Thousands of studies have been attesting to the exceptional electroanalytical performance of these devices, but there are still questions in MWCNT electrochemistry that deserve more investigation, aiming to provide new outlooks and advances in this field. Additionally, MWCNT-based sensors should be further explored for real industrial applications including for on-line quality control.
