“…14 Gradual colour change of nanoparticles sample from light to dark colour is an indication of formation of nanoparticles by reduction of metallic silver ion (Ag + ) into Ag 0 to form AgNPs. 15 It has been reported that metabolites of plant extract trapped on the Ag + ions due to electrostatic interactions between the silver ions and metabolites in plant extract and form their secondary structural change (Ag 0 ) and further reduction of silver nuclei turns in to AgNPs by stabilizing activity of phytochemicals. 16 UV-vis spectroscopy is one of the most commonly used technique for the characterization, stability, morphology, shape, size, and chemical surroundings of synthesized nanoparticles and it provides surface plasmon resonance (SPR) band due to the combined oscillation of electrons on valence band and conduction band on the surface of AgNPs.…”

Characterization of synthesized silver nanoparticles were done by UV-vis spectroscopy, SEM photography, DLS analysis and FTIR analysis. UV-Visible spectra analysis was done by using Parkin Elmer Lambda-25 UV-Visible spectrophotometer. SEM was done Abstract C. reflexa is a parasitic medicinal plant has been used for ailment of different diseases. Aqueous extract of C. reflexa has been used for the synthesis of SNPs .In present work synthesis and characterization of SNPs mediated by C. reflexa aqueous extract has been done. The synthesized SNPs showed SRP at 442.94nm. SEM image analysis provided the spherical shape of the SNPs. DLS analysis provided the synthesized SNPs were 169.10nm in diameter with -23mV zeta potential. FTIR spectroscopy provided the confirmation about synthesis of SNPs by representing various transmission peaks 3062.96cm -1 represented to O-H stretch for alcohol and phenol, 2735.06cm -1 , 2395.59cm -1 , 2063.83cm -1 represented to N-H stretches for primary and secondary amines, 825.53cm -1 for C-H stretch represented to vinyl group. Thus, C. reflexa extract can be used for synthesis of metallic nanoparticles for pharmacological studies. Citation: Ranjan R, Dandapat S, Kumar M, et al.

“…Creation of metallic clusters at ambient pressures is predominantly done through ambient plasma methods [32][33][34] and/or synthetic routes. 35,36 In the work presented here, we provide a further development in the field of ambient soft-landing through the usage of a SLIM system. A nitrogen-gradient pressure was used to look for the effects of laser ablated metallic clusters post soft-landing.…”

Metallic nanoparticles (NPs) have been accepted for various applications ranging from cosmetics to medicine. However, no method has been established in the scientific community that is capable of analyzing various metals, sizes, and levels of exposures without the concern of background chemical contaminations. We present here a system utilizing soft-landing ion mobility (SLIM) exposures of laser ablated metallic clusters capable of operating pressures of reduced vacuum (1 Torr) up to ambient (760 Torr) in the presence of a buffer gas. Clusters experience kinetic energies of less than 1 eV upon exiting the SLIM, allowing for the exposure of NPs to take place in a passive manner. While there is no mass-selection of cluster sizes in this work, it does show for the first time the creation and soft-landing of nanoclusters at ambient pressures. Factors such as area coverage and percentage distribution were studied, as well as the different effects that varying surfaces may cause in the agglomeration of the clusters. Furthermore, the system was successfully used to study the effects of silver nanoparticle exposure and determine the specific organs the NPs accumulate in using zebrafish (Danio rerio) as a model organism. This method provides a novel way to synthesize NPs and expose biological organisms for various toxicological analysis.

“…The process is performed at room temperature (RT) without utilizing any extra solvent. Another attempt was done by Zhang et al (Zhang, Tian, Xiao, Sun, & Li, 2015) to introduce a method for Ag NPs preparation. They mixed the metal precursor AgNO3 with the reducing agent Ascorbic Acid (AA) and grinding the mixture in a solid-state reaction at room temperature for about 30 min.…”

Metal Nanoparticles (NPs) are recognized as the most attractive materials due to their distinct physical and chemical characteristics. Several physical and chemical synthesis methods have already been tested to obtain NPs of appropriate size and shape. Although the chemical-based solution methods provide NPs within a proper size and shape and can be reasonably controlled, they require a large amount of raw material including solvents, capping agents, etc., which usually lead to toxic output and waste. In this study, the author tested an easy and environmentally friendly solid-state synthesis pathway for synthesizing silver (Ag) NPs within a suitable size and shape, using a novel reducing agent. Silver carbonate (Ag2CO3) was allowed to react with Violuric acid (C4H3N3O4) as a reducing agent through a solid-state grinding method for one hour. The results confirmed that Violuric Acid can be considered a promising reducing agent that results in the formation of well-shaped spherical Ag NPs within an average particle size of about 60 nm.
