“…The h-BN NPs were synthesized in de-ionized distilled water (DDW) by exfoliation and fragmentation of BN particles; utilizing a pulsed laser. The nanoparticles were characterized within 2 h of production [32,33]; in addition, the hexagonal boron nitride (h-BN) was synthesized in the route shown in figure 1. Two mg of h-BN powder was disseminated in 50 ml of DDW for 20 min using probe sonication.…”

In this paper, we reported the synthesis of hexagonal BN, Gd2O3 nanoparticles, and BN@Gd2O3 hybrid nanocomposites by novel laser ablation in liquid. Several analytical techniques including X-ray diffraction (XRD), UV-Vis spectroscopy, Fluorescence spectroscopy, Field Emission Scanning electron Microscopy (FE-SEM) with Energy dispersive spectroscopy (EDS), High-resolution transmission electron microscope (HR-TEM), and map imaging were used to investigate the structural and optical properties of synthesized nanoparticles. According to FE-SEM and TEM results, FE-SEM images show the formation of h-BN NPs, sheet-like, and spherical nanoparticles, hexagonal-type nanoflake of Gd2O3, and needle-like shapes. High-resolution transmission electron microscopy images confirm that the average diameter of all samples is ~ 40 nm. However, the length of the nanorods is found to vary from 50 nm to 240 nm. The optical properties studies show that the optical energy gap of h-BN, Gd2O3, and h-BN@Gd2O3 is in the range of (4.5 – 5.5) eV.

“…There is a potential to prepare a new nanosystem, where the components are loaded on a carrier to convey ions, and CNPs are demonstrated to be a good carrier [11]. Different ways are used to produce nanostructured materials [12][13][14][15]; among them, pulsed laser ablation in liquid (PLAL) is the best method for synthesizing different types, sized, and shaped nanomaterials, in addition to other advantages like cost control and without the production for any by-product(s) and purification [16][17][18][19][20][21][22][23][24]. In addition, the NP morphology is prone to modification by using different liquids and laser parameters.…”

Copper oxide (CuO) nanoparticle- (NP-) decorated carbon NPs (CNPs) were produced as colloidal suspension through pulsed laser ablation technique in liquid (PLAL) medium. The antimicrobial activity of the produced NPs was tested against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), and anticancer activity was tested against breast cancer cell line, MCF-7, together with the biocompatibility assessment of these NPs. The X-ray diffraction (XRD) patterns of the obtained CNPs showed peaks at 26.58° and 43.78° (2θ) identical to (002) and (111) planes, respectively, of the carbon phases. It also displayed new peaks at 38.5° and 48.64° (2θ) after doping with CuO NPs. Transmission electron microscope (TEM) images revealed the crystalline nature with the spherical shape of the prepared CNPs with 5-40 nm diameter ranges. In addition, the NP effects on the bacterial cell walls and nucleic acid were confirmed using a scanning electron microscope (SEM) and microscopic fluorescence analysis. The NPs showed antibacterial activity through SEM examinations against the pathogenic microbial species, S. aureus and E. coli. In the cellular material release assay, the optical density of the bacterial cells, treated with NPs, displayed a significant increase with the time of exposure to NPs, and the cytotoxicity reached more than 80% of the level for the CNPs decorated with CuO NPs. The morphology of the MCF-7 cells treated with NPs decreased numbers, and the loss of contact with the surrounding cells was observed. These results confirmed that the CNPs decorated with CuO NPs have no observable side effects and can be safely used for therapeutic applications. It is also noteworthy that it is the first report of preparation of CuO NPs decorated with CNPs (CuO NPs-CNPs) by PLAL, and the produced NPs showed antimicrobial antiproliferative activities against breast cancer cell lines, MCF-7. The main advantage of the PLAL technique of synthesizing CuO NPs-CNPs provided a two-step, cost-effective, and eco-friendly method.

“…To date, several controlled synthesis methods for Ag NPs have been reported such as evaporation condensation, chemical reduction, sol-gel, laser ablation, electron irradiation, microwave processing, electro-chemical, photochemical, and biosynthesis [4,5]. Each method has advantages and disadvantages [6][7][8][9][10]. However, all techniques can be classified into one of two approaches: top-down or bottom-up.…”

The pulsed laser ablation in liquid (PLAL) technique was used to successfully synthesise silver nanoparticles (Ag NPs). With the goal of controlling their size, a laser wavelength of 1064 nm was focused on the Ag bulk target immersed in distilled water in a glass vessel with different laser fluences. The effect of laser fluence, and thus Ag NPs concentration on the bacterial pathogenic was investigated. While the Fourier-transform infrared spectroscopy (FTIR) and x-ray diffraction (XRD) patterns confirm the presence of Ag NPs, UV–vis spectrophotometry revealed a significant absorption peak at around 405 nm, which is attributed to the obtained Ag NPs’ characteristic surface plasmon resonance (SPR) peak. The SPR peak shifted towards a shorter wavelength as the laser fluence was increased, indicating that the Ag NPs have reduced in size. The transmission electron microscopy and size distribution images of Ag NPs clearly showed the effects of laser fluence on size reduction of Ag NPs. Bacteria activity was effectively inhibited by the Ag NPs which are found to be more effective against Gram-negative (Escherichia coli) than Gram-positive strains (Streptococcus aureus). PLAL has proven to be an effective method for controlling the size of NPs, which can be used in a variety of applications.
