“…Silver nanoparticles (AgNPs) synthesis is an expanding research area due to their unique chemical, physical, and biological properties [1][2][3][4] that can lead to a wide range of applications in spectroscopy, sensors, electronics, catalysis, and pharmaceutical sciences [5][6][7][8]. Although several approaches (physical-and chemical-based methods) have been reported in order to prepare AgNPs [9][10][11][12], yet the biosynthesis of NPs can eliminate the requirement of using harmful chemicals while reducing the need for downstream procedures, and as a result make the biosynthesis protocol further low cost, fast, and less energy consuming [13][14][15].…”

Silver nanoparticles (AgNPs) have been biosynthesised through the extracts of Ribes khorassanicum fruits, which served as the reducing agents and capping agents. Biosynthesised AgNPs have been found to be ultraviolet-visible (UV-vis) absorption spectra since they have displayed one surface plasmon resonance peak at 438 nm, attesting the formation of spherical NPs. These particles have been characterised by UV-vis, field-emission scanning electron microscopy, energydispersive X-ray spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy analysis. The formation of AgNPs at 1.0 mM concentration of AgNO 3 has resulted in NPs that contained mean diameters in a range of 20-40 nm. The green-synthesised AgNPs have demonstrated high antibacterial effect against pathogenic bacteria (i.e. Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa). Biosynthesising metal NPs through plant extracts can serve as the facile and eco-friendly alternative for chemical and/or physical methods that are utilised for large-scale nanometal fabrication in various medical and industrial applications.

“…Laser ablation technique is an alternative method for preparation of gold nanoparticles in an aqueous solution. Recently, gold nanoparticles were prepared in graphene oxide and vegetable oils such as pomegranate seed oil [25]. When gold nanoparticles were fabricated using laser ablation of the gold target, the nanoparticles were formed in the spherical shape (Figure 3a) that was investigated using transmission electron microscopy.…”

Recently, the synthesis and application of metal and ceramic nanoparticle are significant subject in science and engineering. The metal nanoparticles such as silver, gold, and copper nanoparticles have more application in material science, nanomedicine, electronic, photonic, and art. One of the green methods for preparation of metal nanoparticles is laser ablation technique that offers a unique tool for nanofabrication of nanoparticles. In this technique, the high-power laser ablates the metal plate and the nanoparticles are formed in the liquid. The properties of nanoparticles using laser ablation are unique, and they are not reproducible by any other method such as chemical methods. The important parameters to produce the metal nanoparticles are energy, wavelength, repetition rate of laser, ablation time, and absorption of an aqueous solution. Laser ablation is a simple method for fabricating the metal nanoparticles without surfactant or chemical addition. In this chapter, the mechanism of formation of metal nanoparticles in liquid, significant parameters for using the laser ablation technique to prepare the metal nanoparticles, and the preparation of silver, gold and copper nanoparticles will be reviewed.

“…The chemical methods normally used convey a reduction step; one of the most widely used is the borohydride reduction in which the injection method is preferred to provide AgNP of 17 ± 2 nm by using a polymeric template [8,9]. In the borohydride method, the silver cation is reduced by the free electron pairs on borohydride molecule [10,11].…”

The Ag nanoparticles and nanoclusters (AgNP, AgNC) have been widely used due to their multiple applications, for example, in catalysts for CO 2 to CO electrochemical reduction, O 2 reduction in fuel cells, interface design for plasmonic resonance experiments and H 2 O 2 or glucose sensors. The chemical methods most used to obtain AgNP, reported in the literature are: borohydride reduction, the Tollens method or the sonication at high concentrations of AgNO 3. One important disadvantage of these methods is the multiple steps required for electrode design, especially in carbon materials, and one of them is MWCNTs, used in some applications mentioned above. Electrodeposition has been reported in the preparation of metallic particles. In this chapter, we described the electropolishing method in the preparation of AgNP and AgNC supported on MWCNT film. An advantage of this proposed method is that it allows obtaining AgNP and AgNC in situ, supported on carbon matrices, ready to use as electrodes in different applications.
