“…After that, a pencil got its name [10], which is now used, although the material currently used is graphite. The lead voltage value is (0.13 V) [11], it is an anti-magnetic metal that is ductile and malleable [12], and it also has corrosion resistance due to passivation [13]. The nanoparticles of PbO have a spherical shape [14].…”

The induced plasma technique was used in the current investigation to create lead oxide nanoparticles from bulk structures at various bombardment periods (4,6,8,10) min. The process will be carried out in the presence of argon gas that flows at a constant rate (3 L/sec). These nanoparticles were created as thin layers on various thicknesses of glass substrates prepared at different times of shelling”. After that, they were analyzed with an x-ray spectrum, scanning electron microscope (SEM), atomic force microscope (AFM) and UV-visible spectrophotometer. Where the optical characteristics and constants were examined, the energy gap of the films varied with bombardment periods from 2.1 ~1.98eV. The SEM and AFM images clearly display a structure that varies with bombardment duration due to the fluctuation in the diameter of the nanoparticles. Finally, the layers' entire amorphous nature is revealed by the x-ray spectrum.

“…To create silver nanoparticles, it is necessary to add chemical reducing agents to silver salt ions and reduce silver ions in boiling water. In addition, stabilizers such as citrate [ 16 ], polyvinyl alcohol [ 17 ], polyvinyl pyrrolidone [ 6 ], bovine serum albumin [ 18 ], and cellulose [ 19 ] are extensively used to avoid aggregation of nanoparticles.…”

Citrate-capped silver nanoparticles Ag@Cit NPs were synthesized by a simple plasma-assisted reduction method. Homogenous colloidal Ag@Cit NPs solutions were produced by treating a AgNO3-trisodium citrate-deionized water with an atmospheric-pressure argon plasma jet. The plasma-synthesized Ag@Cit NPs exhibited quasi-spherical shape with an average particle diameter of about 5.9−7.5 nm, and their absorption spectra showed surface plasmon resonance peaks at approximately 406 nm. The amount of Ag@Cit NPs increased in a plasma exposure duration-dependent manner. Plasma synthesis of Ag@Cit NPs was more effective in the 8.5 cm plume jet than in the shorter and longer plume jets. A larger amount of Ag@Cit NPs were produced from the 8.5 cm plume jet with a higher pH and a larger number of aqua electrons, indicating that the synergetic effect between plasma electrons and citrate plays an important role in the plasma synthesis of Ag@Cit NPs. Plasma-assisted citrate reduction facilitates the synthesis of Ag@Cit NPs, and citrate-capped nanoparticles are stabilized in an aqueous solution due to their repulsive force. Next, we demonstrated that plasma-synthesized Ag@Cit NPs exhibited a significant degradation of methylene blue dye.

“…Among the metal NPs, AgNPs have found appropriate claimants as antimicrobial and anticancer agents; wound healing, drug delivery system and waste water treatment [29][30].Nowadays, harmful chemical substances such as organic dyes have become the root cause of water contamination. So, the catalytic degradation of organic dyes using synthesized AgNPs received the attention of scientists due to the high potential of degrading organic dyes.Other important properties of AgNPs, such as sensing and antimicrobial properties have been addressed previously [31].…”

In recent days, the usage of biological and non-biological pollutants increases and it poses a significant threat to environmental and biological systems. Therefore, the present aim is to develop effective methods to treat such pollutants by using highly stable and small-sized Schiff base ligand capped silver nanoparticles (AgNPs) with a face-centered cubic (fcc) crystalline structure and the size range is 5–10 nm. The potent role of the resulting synthesized AgNPs was found as multiple platforms such as catalyst, sensor, antioxidant, and antimicrobial disinfectant. The synthesized AgNPs were characterized through UV–vis spectroscopy, PL, FTIR, XRD, SEM, and TEM. The FTIR spectrum of AgNPs exhibited the interacted functional groups of Schiff base and size was estimated by XRD and TEM. AgNPs were able to catalytically degrade approximately 95% of methylene blue (MB), rhodamine B (RhB), and eosin Y (EY) dyes within 80 min of reaction time using NaBH4. The fluorometric sensor studies of synthesized AgNPs showed selective sensing of the potentially hazardous Fe2+ ion in water. As an antimicrobial agent, the AgNPs are effective against both Gram-positive and Gram-negative bacteria; as well as fungi, with the zones of clearance as approximately compatible with standard drugs. The AgNPs displayed a greater ability to scavenge free radicals, especially DPPH when compared with AgNPs and ascorbic acid. Thus, the results of this study validate the triple role of AgNPs derived via a simple synthesis as a catalyst, sensor, antioxidant, and antimicrobial agent for effective environmental remediation.
