“…These results demonstrated good selectivity for those metal ions over a wide range of others. Moreover, the presence of organic functional groups in the stabilizing agent also facilitates the binding of metal ions onto the surface of GMAs, eventually enhancing the detection performance [68,69] …”

In this work, the Garcinia mangostana pericarp aqueous extract was utilized as an efficient reducing agent for the phyto‐synthesis of eco‐friendly silver nanoparticles (GM/AgNPs (GMAs)). Characterization of the as‐synthesized material revealed the optimal synthesis conditions of 1 mL of the extract, 1.6 mL of AgNO3, and 1 mL of pH 10 buffer solution at 70 °C for 30 min of reaction. The formation and distribution of quasi‐spherical silver nanoparticles were elucidated with an average particle size of 22.12±1.106 nm, whilst the colloidal system of GMAs also possessed a negative surface charge (−25.4 mV) with such low particle instability parameters (PIP), signifying great stability even after 8 weeks. Furthermore, the material demonstrated excellent bioactivities, wherein a good inhibitory was acquired towards both P. aeruginosa and S. aureus. Besides, the synthesized GMAs provided great catalytic reduction performances, which removed 98.75, 96.55, and 90.85 % of RhB, MO, and 4‐NP, respectively, within 120 s. Along with a low detection limit for surveyed heavy metal ions as well as H2O2 in specific concentration ranges, the phyto‐synthesized GMAs can be efficaciously employed in a wide range of environmental applications, namely in the medical and wastewater remediation sectors.

“…Electrodeposition can be performed by immersing the electrode substrate (disc or 3D electrodes) into the silver salt solution [ 75 ]. In addition, electrodeposition can be carried out from various background electrolytes such as acetic acid(AcOH)/NH 3 buffer [ 76 ], H 2 SO 4 [ 77 ], HNO 3 [ 78 ], KNO 3 [ 79 ] and phosphate buffer solution (PBS) [ 80 ]. For two-dimensional sensors (screen-printed carbon electrodes, inkjet-printed electrodes, doped rigid glass substrates), electrodeposition can also be done by drop casting the Ag(I) solution on the surface of the working electrode and applying a CV in a given timeframe [ 81 ].…”

“…The three-dimensionally ordered crystalline architecture was spread on a 1 × 1 cm 2 indium tin oxide (ITO) glass substrate, and the prepared Ag@MOF/ITO sensor exhibited remarkable sensitivity in voltammetric detection of HMs, with LODs of 0.68 μM (copper) and 0.64 μM (lead), respectively [ 114 ]. An electrochemical deposition method was used to fabricate polyrutin/AgNPs/GCE sensor for voltammetric determination of Pb(II) and Cd(II) in water and soil samples [ 77 ]. To obtain a highly selective sensor, the WE was first immersed in 0.1 M ABS to preconcentrate the target HMs via the complex alloy formation on the electrode surface.…”

With rapidly increasing environmental pollution, there is an urgent need for the development of fast, low-cost, and effective sensing devices for the detection of various organic and inorganic substances. Silver nanoparticles (AgNPs) are well known for their superior optoelectronic and physicochemical properties, and have, therefore, attracted a great deal of interest in the sensor arena. The introduction of AgNPs onto the surface of two-dimensional (2D) structures, incorporation into conductive polymers, or within three-dimensional (3D) nanohybrid architectures is a common strategy to fabricate novel platforms with improved chemical and physical properties for analyte sensing. In the first section of this review, the main wet chemical reduction approaches for the successful synthesis of functional AgNPs for electrochemical sensing applications are discussed. Then, a brief section on the sensing principles of voltammetric and amperometric sensors is given. The current utilization of silver nanoparticles and silver-based composite nanomaterials for the fabrication of voltammetric and amperometric sensors as novel platforms for the detection of environmental pollutants in water matrices is summarized. Finally, the current challenges and future directions for the nanosilver-based electrochemical sensing of environmental pollutants are outlined.

“…Over time, a range of techniques has been developed for detecting heavy metal ions (HMIs) in soil samples, each with its own set of advantages and limitations, including inductively coupled plasma mass spectrometry (ICP-MS) [13,14], inductively coupled plasma optical emission spectrometry (ICP-OES) [15], flame atomic absorption spectrophotometry (FAAS) [16,17] and atomic absorption spectroscopy (AAS) [18][19][20]. These methods vary in their focus, sometimes emphasizing parameters and other times the choice of analysis method.…”

Heavy metals constitute pollutants particularly common in air, water, and soil. They are present in both urban and rural environments, on land and in marine ecosystems, causing serious environmental problems since they do not degrade easily, remain almost unchanged for long periods, and bioaccumulate. Detection, though especially quantification, is a systematic process as monitoring of their levels needs to be carried out at regular intervals since there is often seasonal variation. The need for rapid and low-cost determination of metals is therefore considerable. In the present study atomic absorption spectroscopy (AAS), using a flame or graphite furnace, and square wave anodic stripping voltammetry (SWASV), using a bismuth thin film electrode, a sensitive voltammetric method is being compared and analytically validated. Atomic absorption spectroscopy (AAS) represents a well-established analytical technique while anodic stripping voltammetry is being criticized for its applicability in complicated sample matrices such as soil samples. This sample-handling challenge is being investigated in the present study. The results show that both methods AAS and ASV were satisfactorily correlated and showed that the concentration of metals is lower than the limit values, but with increasing trend. Therefore, continuous monitoring of metal levels in the urban complex of the city is necessary and a matter of great importance. Regarding Cd, the detection limits of Cd are lower compared to those of AAS when using the graphite furnace, while an overestimation was noted when using flame-AAS in comparison with those found with SWASV. The SWASV method has the advantage of being cheaper and faster, enabling the simultaneous determination of heavy elements across the range of concentrations that these elements can occur in Mediterranean soils. Additionally, we applied a dsDNA-modified electrode which can be used in the speciation analysis of Cu(I) and Cu(II). The changes in the characteristic peaks of guanine and adenine can be applied in the redox speciation analysis of copper in soil which represents an issue of great importance.
