Stability of Silver Nano Particles in Deionized Water Produced by using the Low-Energy Nd : YAG laser

Abstract

Nanoparticle stability is essential for its usage in a wide range of fields, including healthcare. Therefore, the purpose of this study is to evaluate the safety of silver nanoparticles in deionized (DI) water using low-energy laser ablation. In this research, a Nd: YAG laser (Q-smart 850 by Quantel) was utilized to produce radiation at 1064 nm and 50 mJ of energy. 10 minutes were spent blasting deionized water full of colloidal silver nanoparticles at a frequency of 10 Hz (DI water). After 30 days, the photos demonstrate that the color of the colloidal SNPs has changed to be more transparent, and no agglomeration or precipitation has taken place. The little impact of Brownian motion and the evenly distributed population of SNPs contribute to their stability. Because the nanoparticles in the colloid were slightly diluted, the absorbance dropped. When subjected to a low-energy laser, they maintain their spherical shape. Colloidal silver nanoparticles have a golden yellow hue. There has been no variation in the colloidal SNPs after 30 days. Spectral analysis of colloidal silver nanoparticles reveals an SPR peak at 403 nm. The average size of silver NPs was measured to be 28 nm using the ImageJ software. The shape of silver nanoparticles is typically spherical.
