“…(UV) spectroscopy (Asfaram, Ghaedi, & Dashtian, 2017), highperformance liquid chromatography (HPLC; Fernandes, Batista, de Medeiros, Santos, & Medeiros, 2015), ultrahigh-performance liquid chromatography−tandem mass spectrometry (Newsome, Li, & van Breemen, 2016), thin layer chromatography (Anandjiwala, Srinivasa, & Rajani, 2007), and electrochemical techniques (Shojaei, Nasirizadeh, Entezam, Koosha, & Azimzadeh, 2016). Among these approaches, electrochemical analysis is one of the most facile methods due to its advantages of low cost, high sensitivity, and efficiency (Baig, & Sajid, 2017), and a variety of modified electrodes have been developed to improve the electrochemical signal response of the analyte (Balasubramanian, Balamurugan, Chen, Chen, & Lin, 2019;Devi et al, 2019). Based on the oxidizable characteristics of GA, voltammetry, including cyclic voltammetry, differential pulse voltammetry, stripping voltammetry, and square wave voltammetry, has been employed in almost all electrochemical measurements of GA (Abbasi, Daneshfar, Hamdghadareh, & Farmany, 2011;Shahamirifard, Ghaedi, Razmi, & Hajati, 2018;Tashkhourian, & Nami-Ana, 2015).…”

Molecularly imprinted polymers (MIPs) have become a valuable material in the field of electrochemical sensors, due to their selective recognition capabilities towards target molecules. A low‐cost potentiometric sensor based on molecular imprinting was developed for the measurement of gallic acid (GA) in edible plants. The imprinted polymer was synthesized by bulk polymerization in the presence of trimethylolpropane triacrylate as the cross‐linker and 2,2’‐azo‐bisisobutyronitrile as the initiator. The sensing component of the sensor was fabricated by the incorporation of MIPs in a polyvinyl chloride matrix. The species and amount of MIPs were optimized, and the imprinted poly(methacrylic acid) sensor was examined and characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and potential response. The proposed sensor exhibited a fast near‐Nernst response to GA in the range of 1 × 10−5 to 3.2 × 10−4mol/L. The potentiometric measurement of GA in edible plants was checked by high‐performance liquid chromatography, and the two test results showed no significant difference (P > 0.05). The imprinted sensor is applicable to the electrochemical determination of GA in edible plants. Practical Application The proposed MIP‐based potentiometric sensor provided a low‐cost, efficient, and green tool for the rapid determination of the bioactive ingredient GA in edible plants. The knowledge obtained will offer useful reference to the quality control and bioactive assessment of botanical food.

“…In recent years, electrochemical methods and particularly voltammetry, have attracted significant attention due to their benefits like sensitivity, simplicity, low cost, accuracy and selective specification of electroactive species [15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In addition, the usage of electrochemical approaches towards detection of FA is generally promising because FA is the electrochemically active compound [29,30].…”

In the field of determination of vitamin B9 (folic acid, FA), we have described the development of a sensitive electrochemical sensor through promoting the screen-printed electrode (SPE) and taking the advantage of zinc ferrite magnetic nanoparticles (ZnFe2O4MNPs). Cyclic voltammetry (CV) experiments demonstrated the powerful activity of ZnFe2O4MNPs/SPE for electrooxidation of FA by showing the prominent oxidation peak at 600 mV vs. Ag/AgCl. By differential pulse voltammetry (DPV) measurements, a linear relation between current response and concentration of vitamin B9 was determined in the range of 1.0–100.0 µM, and detection limit is found to be 0.3 µM (S/N=3). Except high sensitivity, the developed sensor demonstrated high stability, reproducibility and repeatability, and was also successfully applied to specify FA in real samples of vitamin B9 tablets and human urine.

“…These determinations guarantee the safety, quality and traceability of food, in compliance with legislation and consumers’ demands. In this framework, the use of noble metal nanoparticles was recently suggested as an alternative to classical methods of determination [54]. NPs could improve the analytical accuracy, precision, detection limits, and sample quantity, thereby expanding the practical range of food applications [2].…”

“…An amperometric immunosensor for the detection of monosodium glutamate (MSG) was recently reported by Devi et al In this sensor, the anti-glutamate antibody was immobilized on to the sensor surface, composed of a carbon electrode modified with gold nanoparticles decorated on a molybdenum disulfide/chitosan (Au@MoS2/Ch) nanocomposite. This method was validated and showed limit of detection and limit of quantification values of 0.03 and 0.1 µM, respectively, with a detection range of 0.05–200 µM [54]. A method based on optical absorption was developed by Li et al for the rapid detection of L-cysteine with gold nanoparticles on a graphene oxide substrate, as sensitive nanoprobes.…”

Scientific research in the nanomaterials field is constantly evolving, making it possible to develop new materials and above all to find new applications. Therefore, nanoparticles (NPs) are suitable for different applications: nanomedicine, drug delivery, sensors, optoelectronics and food control. This review explores the recent trend in food control of using noble metallic nanoparticles as determination tools. Two major uses of NPs in food control have been found: the determination of contaminants and bioactive compounds. Applications were found for the determination of mycotoxins, pesticides, drug residues, allergens, probable carcinogenic compounds, bacteria, amino acids, gluten and antioxidants. The new developed methods are competitive for their use in food control, demonstrated by their validation and application to real samples.
