“…However, the poor response of bare electrodes in curcumin direct analysis has led to the use of modified electrodes. Numerous sensing strategies based on functional electrodes and nanostructured materials, such as polymer films, metal and carbon NPs, NFs, nanowires (NWs), quantum dots (QDs), carbon nanotubes (CNTs), Gr, GO, reduced graphene oxide (rGO), metal-organic frameworks (MOFs), and molecularly imprinted polymers (MIPs), have been reported [43,44].…”

Curcumin is a natural polyphenol derived from turmeric (Curcuma longa) root that has been used for centuries as a spice, coloring agent, and medicine. Curcumin presents anti-inflammatory, antioxidant, anticarcinogenic, antimicrobial, antiviral, antimalarial, hepatoprotective, thrombosuppressive, cardiovascular, hypoglycemic, antiarthritic, and anti-neurodegenerative properties. It scavenges different forms of free radicals and acts on transcription factors, growth factors and their receptors, cytokines, enzymes, and genes, regulating cell proliferation and apoptosis. Curcumin is electroactive, and a relationship between its electron transfer properties and radical-scavenging activity has been highlighted. The objective of this review is to provide a comprehensive overview of the curcumin electron transfer reactions, with emphasis on the controversial aspects related to its oxidation mechanism. The final sections will focus on the electroanalysis of curcumin in natural products, highlighting the most important sensing strategies, based on functional electrodes and nanostructured materials, essential for the development of more efficient in vitro methods of detection and quantification of curcumin in food samples, supplements, and nutripharmaceuticals.

“…A few examples of voltammetric determination of CU in spices were discussed in 2018 by Ziyatidinova and Budnikov [80] in a review paper related to the analytical chemistry of spice antioxidants. The examples of CU electrochemical detection presented in 2019 by Mohajeri et al [81] in a synthesizing article that addressed the interaction between CU and carbon-based nanomaterials were limited only to the biosensors using this type of sensing material. In a recent review on the CU extraction and analysis procedures, electrochemical methods and sensors are mentioned [12].…”

Curcumin (CU) is a polyphenolic compound extracted from turmeric, a well-known dietary spice. Since it has been shown that CU exerts beneficial effects on human health, interest has increased in its use but also in its analysis in different matrices. CU has an antioxidant character and is electroactive due to the presence of phenolic groups in its molecule. This paper reviews the data reported in the literature regarding the use of electrochemical techniques for the assessment of CU antioxidant activity and the investigation of the voltammetric behavior at different electrodes of free or loaded CU on various carriers. The performance characteristics and the analytical applications of the electrochemical methods developed for CU analysis are compared and critically discussed. Examples of voltammetric investigations of CU interaction with different metallic ions or of CU or CU complexes with DNA as well as the CU applications as electrode modifiers for the enhanced detection of various chemical species are also shown.

“…Curcumin, the principal curcuminoid, possesses inherent electrocatalytic properties and has been reported to amplify the electrochemical response in sensor applications [ 1 , 2 ]. Structurally, the binding of CM to an analyte could be easily identified by spectroscopically analyzing the peaks corresponding to CM’s keto-enol moiety, phenolic, and methoxy group, leading to improved electrochemical response [ 3 ]. For enhanced sensing performance, CM conjugated with various carbonaceous nanostructures has been reported [ 1 , 2 , 3 ].…”

This work reports the development of novel curcuminoid-based electrochemical sensors for the detection of environmental pollutants from water. In this study, the first set of electrochemical experiments was carried out using curcumin-conjugated multi-walled carbon nanotubes (MWCNT–CM) for 1,4-dioxane detection. The MWCNT–CM/GCE showed good sensitivity (103.25 nA nM−1 cm−2 in the linear range 1 nM to 1 µM), with LOD of 35.71 pM and LOQ of 108.21 pM. The second set of electrochemical experiments was carried out with bisdemethoxy curcumin analog quantum dots (BDMCAQD) for hydrazine detection. The BDMCAQD/GCE exhibited good sensitivity (74.96 nA nM−1 cm−2 in the linear range 100 nM to 1 µM), with LOD of 10 nM and LOQ of 44.93 nM. Thus, this work will serve as a reference for the fabrication of metal-free electrochemical sensors using curcuminoids as the redox mediator for the enhanced detection of environmental pollutants.
