Preparation Conditions

Ag nanoparticles were prepared using Nd:YAG laser from Ag matel in distilled water using different energies laser (100 and 600) mJ using 200 pulses, and study the effect of the preparation conditions on the structural characteristics of and then study the effect of nanoparticles on the rate of killing the two types of bacteria particles (Staph and E.coli). The goal is to prepare the nanoparticle effectively used to kill bacteria.

Ag nanoparticles colloids have been fabricated by pulsed laser ablation in various liquids. The particle size, morphology and absorption spectroscopy of the obtained nanoparticles colloids were characterized by ultraviolet to visible (UV-Vis) spectrophotometer and transmission electron microscopy (TEM), the average diameter and its distribution were analyzed by Image-ProPlus software. The results showed that the Ag nanoparticles with best characterization are those produced at the repetition rate of 10Hz and laser fluence of 4.2J/cm2 by ablating for 7.5min in the distilled water, with the least average diameter(D=14.48 nm), the narrowest distribution of particles size (=25.8 nm) and more homogeneous morphologies. The effects of experimental conditions on the silver nanoparticles colloid can be explained by fragmentation and melting induced aggregation of colloidal particles by self-absorption of laser pulses.

Specific Morphology

Two dimensional (2D) materials are widely attracting the interest of researchers due to their unique crystal structure and diverse properties. In the present work, tungsten disulfide (WS[Formula: see text] nanorods were synthesized by a simple method of pulsed laser ablation in liquid (PLAL) environment. The prepared WS2 are analyzed by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), UV-visible spectroscopy (UV-vis) and Raman spectroscopy to confirm the surface morphology, phase and structure. A possible growth mechanism of WS2 is proposed. This study indicates new door for the preparation of 2D materials with specific morphology.
