“…The pH plays a very important role in the properties of the NPs [ 42 ] prepared, including their SERS activity [ 43 ]. A change in the ionic strength in the medium leads to the formation of clusters of particles or even a monolayer of particles on a surface.…”

Gold and silver nanoparticles (NPs) were prepared in water, acetonitrile and isopropanol by laser ablation methodologies. The average characteristic (longer) size of the NPs obtained ranged from 3 to 70 nm. 4-Aminobenzebethiol (4-ABT) was chosen as the surface enhanced Raman scattering (SERS) probe molecule to determine the optimum irradiation time and the pH of aqueous synthesis of the laser ablation-based synthesis of metallic NPs. The synthesized NPs were used to evaluate their capacity as substrates for developing more analytical applications based on SERS measurements. A highly energetic material, TNT, was used as the target compound in the SERS experiments. The Raman spectra were measured with a Raman microspectrometer. The results demonstrate that gold and silver NP substrates fabricated by the methods developed show promising results for SERS-based studies and could lead to the development of micro sensors.

Colloidal gold is very attractive for several applications in biotechnology because of its unique physical and chemical properties. Many different synthesis methods have been developed to generate gold nanoparticles (AuNPs). Here, we will introduce these methods and discuss the differences between fabrication techniques. We will also discuss ecofriendly synthesis methods being developed to efficiently generate AuNPs without the use of toxic substrates. Finally, we will discuss the medical applications for AuNPs by highlighting the potential use of intact or functionalized AuNPs in combating bacterial infections.

“…PLA in a liquid medium also provides the ability to easily control the size and shape of the produced nanoparticles [28][29][30][31]. PLA of a tin target in an ethanol solution of thioacetamide was reported to produce hollow tin monosulfide nanoparticles after acid etching was employed [32].…”

Nickel nanoparticles with various structures were synthesized by a pulsed laser ablation process in liquid CO 2 at 17°C and 5.2 MPa. A nickel plate immersed in liquid CO 2 was used as a target. This was irradiated by a laser beam with a fundamental wavelength of 1064 nm at 2.46 mJ for 15 min. The generated particles were deposited on a silicon wafer after natural evaporation of the liquid CO 2 , and analyzed by field emission scanning electron microscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Nickel and carbon particles with sphere-like structures or apple-shaped structures were observed. Furthermore, characteristic nickel/carbon particles with core/shell structures were also produced. The generated particles ranged in size between 5 and 350 nm in diameter, with dominant sizes under 50 nm.
