“…After being successfully tested in the presence of 12 possible interfering compounds, the sensor was finally used to quantify the amount of caffeic acid present in carbonated soft drinks and red wine without sample pretreatments. The results were compared with those obtained by HPLC as reference method, showing very good accuracy of the proposed amperometric method [ 55 ]. In the last two years several electrochemical sensors have been proposed in the literature for the detection of quercetin.…”

Biosensors and Sensing Systems for Rapid Analysis of Phenolic Compounds from Plants: A Comprehensive Review

2020

View full text Add to dashboard Cite

Phenolic compounds are secondary metabolites frequently found in plants that exhibit many different effects on human health. Because of the relevant bioactivity, their identification and quantification in agro-food matrices as well as in biological samples are a fundamental issue in the field of quality control of food and food supplements, and clinical analysis. In this review, a critical selection of sensors and biosensors for rapid and selective detection of phenolic compounds is discussed. Sensors based on electrochemistry, photoelectrochemistry, fluorescence, and colorimetry are discussed including devices with or without specific recognition elements, such as biomolecules, enzymes and molecularly imprinted materials. Systems that have been tested on real matrices are prevalently considered but also techniques that show potential development in the field.

“…Up to the present, various analytical methods have been developed for CA determination which include liquid chromatography, capillary electrophoresis, as well as electrochemical methods [7,[66][67][68][69]. Among the methods mentioned, the electrochemical ones are preferred due to their excellent sensitivity, fast response, good selectivity, low cost, reliability, and simplicity [1,69]. In the case of electrochemical techniques, the selective determination depends mainly on the electroactivity of the analyte, but the sensitive material also influences this type of determination.…”

“…Caffeic acid (CA) (3,4-dihydroxycinnamic acid) is one of the main phenolic derivatives, usually found in red wine, green tea, coffee, fruits, and vegetables [1][2][3]. An exceptional source of free or bound CA is the fruit of the plant called wild cherry (chokecherry), Prunus virginiana, native to North America [4].…”

Caffeic acid is one of the most important hydroxycinnamic acids found in various foods and plant products. It has multiple beneficial effects in the human body such as antioxidant, antibacterial, anti-inflammatory, and antineoplastic. Since overdoses of caffeic acid may have negative effects, the quality and quantity of this acid in foods, pharmaceuticals, food supplements, etc., needs to be accurately determined. The present paper analyzes the most representative scientific papers published mostly in the last 10 years which describe the development and characterization of voltamperometric sensors or biosensors based on carbon nanomaterials and/or enzyme commonly used for detecting caffeic acid and a series of methods which may improve the performance characteristics of such sensors.

“…Along with the MS family, Nickel sul de semiconducting NPs include a potential candidate for diverse applications such as lithium-ion batteries, electrochemical supercapacitors, light-emitting diodes, photocatalysis, eld-effect transistors and solar cell, etc., [3,[6][7][8][9][10][11]. Besides, various types of preparation methods are followed to prepare MS NPs with different structures and shapes (for example, sonochemical, re ex technique, sol-gel, microwave illumination, hydrothermal, and thermolysis technique) using a single source [3,[12][13][14][15][16] [17,18]. At present, the two possible solutions for energy demands are available in the marketplace; they are supercapacitors and hybrid batteries.…”

High-performance energy storage electrode materials are emerging demand in near future for the construction of supercapacitor with high energy and power densities. Herein, Nickel (II) Diethyldithiocarbamate was used as single source precursor for Nickel Sulfide (Ni9S8) two dimensional (2D) nanosheets preparation and hexadecylamine as shape directing agent via simple solvothermal method. The orthorhombic structure of Ni9S8 nanosheets was confirmed by X-ray diffraction (XRD) pattern. Scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) images revealed that as-prepared Ni9S8 nanoparticles possess sheet-like morphology. Besides, the thermal stability of Ni(DTC)2 complex was studied by Thermo-gravimetric/Derivative thermo gravimetric(TG/DTG) with Differential scanning calorimetric (DSC) analysis. The electrochemical properties of Ni9S8 nanosheets was studied using galvanostatic charge-discharge (GCD) and cyclic voltammetry (CV) techniques. From the charge-discharge study of Ni9S8 nanosheets, a high specific capacitance of 281 Fg− 1 was obtained at a current density of 1 Ag− 1, and up to 82 % retentivity was achieved after 5000 cycles. Thus, the prepared Ni9S8 nanosheets could be one of the attractive potential active electrode materials for the application of supercapacitor.
