“…The various NP synthesis techniques, ltering methods, lter paper properties, and other pertinent factors affect Hg solid-phase extraction. 47 By using lter paper that has been treated with AgNPs, the technique enables the direct analysis of mercury without the need for further digestion or desorption processes. This makes it possible to determine mercury at ultra-trace levels and streamlines the preconcentration procedure.…”

“…Moreover, the technique shows excellent selectivity for Hg 2+ sorption, with recoveries for synthetic waters and veried reference materials ranging from 92% to 105%. 47 An inventive method for the synthesis of AgNPs using lignin as a reducing and stabilizing agent under solar light was presented by Zhang et al The AgNPs were tangled in lignin aer being placed onto the surface of lignin nanoparticles (LNPs) with an average size of around 14 nm and a consistent shape. 48 When it came to Hg 2+ detection, the AgNP-LNP solution exhibited excellent sensitivity and selectivity.…”

“…De la Calle et al [ 100 ] described a filtration device on cellulose paper modified with different metal nanoparticles (i.e., AgNPs, PdNPs, AuNPs) for the selective preconcentration of Hg(II). However, in this work, detection on the cellulose substrate was not attempted and Hg was directly measured in vapor phase after complete combustion of the substrate.…”

The development of disposable sensors that can be easily adapted to every analytical problem is currently a hot topic that is revolutionizing many areas of science and technology. The need for decentralized analytical measurements at real time is increasing for solving problems in areas such as environment pollution, medical diagnostic, food quality assurance, etc., requiring fast action. Despite some current limitations of these devices, such as insufficient detection capability at (ultra)trace level and risk of interferent effects due to matrix, they allow low-cost analysis, portability, low sample consumption, and fast response. In the last years, development of paper-based analytical devices has undergone a dramatic increase for on-site detection of toxic metal ions and other pollutants. Along with the great availability of cellulose substrates, the immobilization of receptors providing enhanced recognition ability, such as a variety of nanomaterials, has driven the design of novel sensing approaches. This review is aimed at describing and discussing the different possibilities arisen with the use of different nanoreceptors (e.g., plasmonic nanoparticles, quantum dots, carbon-based fluorescent nanoparticles, etc.) immobilized onto cellulose-based substrates for trace element detection, their advantages and shortcomings.

“…These techniques are favored for their superior analytical capabilities, delivering precise results with high accuracy and sensitivity. Nevertheless, they come with significant drawbacks such as high costs, lengthy analysis periods, and intricate sample preparation procedures [10]. Moreover, given the typically low concentrations of heavy metals like mercury in cosmetic products, there's a pressing need for developing more efficient methods to analyze such minute amounts effectively.…”

The carcinogenic and teratogenic properties of mercury have driven the necessity for the development of highly sensitive methods capable of detecting even trace amounts of the element. In response to this need, an analysis technique has been established for mercury ions, employing preconcentration methods utilizing filter paper modified by silver nanoparticles (AgNPs) and 3-Amino propyl trimethoxy silane (APTMS). This method allows for the detection of mercury ions through the voltammetry technique, ensuring accurate and reliable results. Upon conducting analyses using this method, it was found that the tested cosmetic samples were free from Hg2+ ions, indicating the absence of mercury contamination in the cosmetics under investigation. The correlation coefficient derived from the graph of the analysis results stands at an impressive value of 0.9976, affirming the strong relationship between the measured concentrations and the actual mercury content. Additionally, the method demonstrates excellent sensitivity, as evidenced by the low limit of detection (LOD) value of 0.0483 mM and the limit of quantification (LOQ) value of 0.1611 mM.
