Recent advances in silver nanoparticle-based electrochemical sensors for determining organic pollutants in water: a review

“…Additionally, thiodicarb was detected at an AgNPs/silver solid amalgam electrode depending on the electrochemical reduction of two symmetric carbonyl groups in the molecule involving four protons and four electrons 168 . Also, trichloroacetic acid could be detected at maleic acid-AgNPs/GC through its irreversible reduction to dichloroacetic acid 169 . Moreover, the reduction mechanism was reported for oxazepam detection 170 .…”

Recent Advances on Electrochemical Sensors for the Detection of Organic Disinfection Byproducts in Water

“…Therefore, they have been considered as more promising alternatives as electrode materials and received far more attention in electrochemical detection of DBPs (see Table ). In reported literature, glassy carbon electrode (GCE) − ,,,, and carbon paste electrode (CPE) are examples of carbon electrodes. Between them, an improved version of CPE, such as carbon ionic liquid electrode (CILE), has been developed and utilized as it is a strong preference for electrochemical sensors − ,− ,− ,− ,, owing to less electrode fouling and better electron transfer kinetics .…”

“…As a result, electrodes modified by the introduction of metal nanoparticles or oxides produced more sensitive sensors compared with electrode–metallic additive–redox protein assemblies. Bashami et al developed a glass carbon electrode (GCE) modified with AgNPs and malic acid (MA) for electrochemical biosensing of TCA . In their work, MA was used as a cross-linker and immobilizer for AgNPs through hydrogen bonding as well as electrostatic effect, which is shown in Figure a.…”

“…Chen et al observed a similar enlargement of detection range when DPV measurements were applied73 . Bashami et al attempted to develop a background interference-eliminated analytical method for the electrochemical determination of TCA, in which reduction peak of TCA using SWV were most distinctive compared with CV and DPV under identical experimental conditions72 .In addition to voltammetry or amperometry, impedance or resistance-related monitoring, such as electrochemical impedance spectroscopy (EIS), is another promising analytical technique for monitoring chemical or physical changes of electrode surface, which displays many advantages such as low cost, fast and stable response, ease of operation and high sensitivity. For EIS measurements, AC signals of different frequencies are applied between the electrodes while the voltage and current are monitored.…”

The Effect of Physicochemical Properties of Perfluoroalkylsilanes Solutions on Microtribological Features of Created Self-Assembled Monolayers

“…In recent years, nanotechnology has become one of the most dynamic developing fields of modern science [1][2][3], which allows structures to be obtained at the nanometer scale and new materials to be obtained with specific properties and consequently application of those materials for the miniaturization of devices [3][4][5]. The construction of devices with contact surfaces of the order of micro-and even nanometers resulted in the need to search for new nanomaterials as well as substances to protect their surfaces.…”
