“…Generally, the target is located prior to the focal plane of the optical system, specifically, the focusing lense, to avoid optical breakdown in the liquid medium during the ablation process, while the laser spots on the target surface have diameter sizes ranging from millimeters to microns. Also, suitable modifications to the experimental setup can be made in order to increase the efficiency of the ablation rate by positioning the target at different angles (0°, 45°, 90°) during PLAL processes [53][54][55][56][57].…”

Pulsed laser ablation in liquids (PLAL) is a physical method that is applied for the fabrication of noble metal nanostructures with different optical and morphological properties. The physical mechanism of laser ablation in liquid environment, the subsequent growth of nanostructures, the essential laser technological parameters that determine the nanostructures’ properties, and the liquid medium’s influence are discussed. The main advantages and disadvantages of the PLAL method are noted. Post-ablation treatment at optimal laser wavelength, fluence and duration of exposure has been indicated as a means of mitigating and overcoming the latter. The aging effect of the colloids and some applications of them are also marked. The most commonly used methods for studying the nanostructures’ characteristics such as UV/vis spectroscopy, high-resolution scanning transmission electron microscopy (HR-STEM), mass spectrometry (MS) and X-ray diffraction (XRD) are commented.

“…To see the morphology and size of tin oxide (SnO2) nanoparticles, a Transmission Electron Microscope (TEM) test was performed. The image results from the TEM test were then processed using ImageJ software to determine the size distribution of the resulting tin oxide (SnO2) nanoparticles (SnNPs) [8].…”

Tin oxide nanoparticles (SnNPs) are very useful to be employed as an antibacterial agent for both gram-positive and gram-negative bacteria. In this present work, the synthesis of SnNPs was successfully carried out using the neodymium yttrium aluminum garnet (Nd:YAG) laser with a wavelength of 1064 nm, pulse duration of 7 ns, and a laser frequency of 10 Hz. Experimentally, a pulse Nd:YAG laser was directed and focused on a high-purity tin (Sn) metal, immersed in various liquid media including pure water and ethylene glycol. A brownish colloidal colour was produced both in pure water and ethylene glycol liquid media. Characterizations of tin oxide nanoparticles were made using UV-Vis, EDX, FTIR, and TEM. UV-Vis characterization produced absorbance values in pure water and ethylene glycol media of 1.314 a.u. and 1.119 a.u., respectively. TEM images show that the shape of tin oxide nanoparticles produced is spherical. Measurement of nanoparticle size distribution was made using image-J software and the average diameter of nano-size in the ethylene glycol medium is 12.55 nm, which is smaller than the size in the pure water of 19.98 nm. The EDX spectrum analysis results show that there are only Sn and O atoms in colloidal tin oxide nanoparticles (SnNPs). FTIR results show the formation of tin oxide (SnO2) spectrum at the wavenumber of 629.03 cm-1. The produced colloidal SnNPs were then applied as an antibacterial agent of E. coli using the disk diffusion method. Results certified that various concentrations of SnNPs of 10 ppm, 20 ppm, and 30 ppm gain the diameter of inhibition zone (DIZ) in sequence 6.50 mm, 6.75 mm, and 9.50 mm. Based on these experimental results, it shows that the higher the concentration of SnNPs given, the greater the ability to degrade and inhibit bacteria.
