REVIEW OF SILVER NANOPARTICLE SYNTHESIS USING LASER ABLATION; ITS CHARACTERIZATION, ANTIOXIDANT AND ANTIBACTERIAL FOR SKIN WOUNDS

This comprehensive review paper thoroughly investigates the synthesis of silver nanoparticles (AgNPs) through laser ablation and biosynthesis methods, exploring their potential applications in nanotechnology. The paper highlights the distinctive properties of AgNPs, including their notable antibacterial and anticancer attributes, wound healing capabilities, and therapeutic potential. The focus is specifically on the synthesis of small, spherical particles ranging from 2 to 5 nm. This investigation centers on key parameters crucial to the synthesis process, such as laser beam spot size, strength, ablation duration, and green synthesis factors like time, temperature, and concentration. In the realm of laser ablation optimization, the study scrutinizes the impact of various spot sizes on particle size distribution, variations in laser strength, and the intricate relationship between ablation duration and particle size. These analyses are strategically aligned to achieve the desired properties for the efficient production of AgNPs. Simultaneously, green synthesis techniques are employed to ensure an environmentally friendly approach, with careful consideration for factors like time, temperature, and concentration to attain targeted characteristics. The paper employs sophisticated characterization techniques, including dynamic light scattering (DLS), scanning electron microscopy (SEM), and UV-Vis spectral analysis, for a comprehensive analysis of the synthesized AgNPs. DLS offers insights into size distribution and stability, SEM facilitates morphology visualization, and UV-Vis spectral analysis definitively confirms the presence of silver nanoparticles through characteristic absorption peaks.
