“…Considering the control group of deionized water as a reference standard, among the seven tested metal ions, only mercury reacted to the AgNPs. Other scholars have also conducted tests using the same interferents, and the metal ions with a concentration of 1.5–3 μM did not undergo a coloring reaction with AgNPs, except for mercury ions [ 54 , 55 ]. Based on the above analysis results, it can be concluded that the AgNPs synthesized by the chemical reduction method using trisodium citrate and sodium borohydride as the capping and reducing agents, respectively, can specifically detect mercury ions.…”

Silver nanoparticles (AgNPs) have stable reactivity and excellent optical absorption properties. They can be applied in various industries, such as environmental protection, biochemical engineering, and analyte monitoring. However, synthesizing AgNPs and determining their appropriate dosage as a coloring substance are difficult tasks. In this study, to optimize the process of AgNP synthesis and obtain a simple detection method for trace mercury in the environment, we evaluate several factors—including the reagent addition sequence, reaction temperature, reaction time, the pH of the solution, and reagent concentration—considering the color intensity and purity of AgNPs as the reaction optimization criteria. The optimal process for AgNP synthesis is as follows: Mix 10 mM of silver nitrate with trisodium citrate in a hot water bath for 10 min; then, add 10 mM of sodium borohydride to produce the AgNPs and keep stirring for 2 h; finally, adjust the pH to 12 to obtain the most stable products. For AgNP-based mercury detection, the calibration curve of mercury over the concentration range of 0.1–2 ppb exhibits good linearity (R2 > 0.99). This study provides a stable and excellent AgNP synthesis technique that can improve various applications involving AgNP-mediated reactions and has the potential to be developed as an alternative to using expensive detection equipment and to be applied for the detection of mercury in food.

Water and cosmetics containing mercury can cause damage to the skin and body. There is a great need for in situ monitoring and removal of mercury ion concentrations with a highly selective, sensitive, accurate, rapid, and simple protocol in water and skin-whitening cosmetic products. In situ recognition is an easy and inexpensive approach for recognition and uptake of Hg 2+ ions in skin-lightening cosmetics and water. Our system is based on the fabrication of a sticklike structure of the newly developed metal−organic framework (MOF) via a solvothermal protocol. The rodlike structure of the Al-MOF has a tremendously high surface area which is a powering point that supported it as a microporous substrate for loading a Hg 2+ ion chromophore (bis(4-(dimethylamino)phenyl)methanethione). The thioketone derivative chromophore based on an Al-MOF microporous carrier allows visual monitoring of toxic mercury in a few seconds. The proposed chemosensors have a color change from yellow to a green color that is extremely noticeable by the naked eye. Our designated chemosensors sensitivity (0.8 ppb) toward mercury ions was found to be lower than the WHO permissible drinking water limits which made it a good choice for in situ pretests of drinking water. Moreover, superior adsorption characteristics of the fabricated thioketone Al-MOF (TAM) nanorods as adsorbent were achieved. A high adsorption capacity was observed (1110 mg/g) in solution for capturing of mercury ions. Our developed protocol is built on the use of a small amount of prepared optical chemosensors, about 20 mg, for all measurements and the potential for multiple uses after a simple regeneration process. Our results revealed that the designed TAM nanorods would be a promising means of visualizing mercury ions in water and cosmetics products.

“…Further investigation has been carried out to systematically study the DNA design dependency of the segmented DNA-induced AuNPs aggregation toward versatile bioassay development. 214 In another example, Kataria et al 215 designed a colorimetric biosensor for detecting mercury ions based on the antiaggregation approach where aggregation of metal NPs is prevented in the presence of the analyte. In this assay, 5-dimethyl-1-thiocarboxamidepyrazole causes the accumulation of AuNP and changes color from red to blue.…”

Nature has inspired scientists to develop green and sustainable nanomaterials with biomimetic functions. Particularly, biomimetic metallic nanostructures (biometal NPs) with unique optical, catalytic, and electrical properties have received tremendous attention in many fields, ranging from healthcare and agriculture to energy and environmental sciences. Biometal NPs synthesized by various natural resources such as plant extracts, biomolecules, bacteria, and even viruses possess unique biomimetic functions including but not limited to precise biorecognition, selfassembly, antibacterial/antiviral, and enzymatic properties. In this report, we first review the bioinspired synthesis of industrially important metal nanoparticles, followed by the discussion on how the different biological sources affect the biomimetic functions of the as-synthesized biometal NPs. Next, we review the recent advancement and applications of these biometal NPs in the fields of biomedical engineering and catalysis, which include the development of metallic nanobiosensors, biomedical imaging probes, nanotherapeutics (e.g., antimicrobial and photodynamic/photothermal therapeutic agents), as well as the design of multifunctional nanozymes and artificial metalloenzymes for chemical and biopharmaceutical industries. Finally, we highlight some of the latest advancements in nanobiomimicry and their emerging applications in clean energy, electronic devices, and data storage, which shows the game-changing role of biomimetic metallic nanostructures for various technological applications in the near future.
