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 discusses the properties of AgNPs, including their antibacterial, anticancer, wound healing, and therapeutic potential. It synthesizes small, spherical particles and analyzes key parameters like laser beam spot size, strength, ablation duration, and green synthesis factors. These analyses are strategically aligned to achieve the desired properties for producing AgNPs efficiently. Simultaneously, green synthesis techniques ensure an environmentally friendly approach, carefully considering 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 UVVis spectral analysis, to comprehensively analyze the synthesized AgNPs. DLS offers insights into size distribution and stability, SEM facilitates morphology visualization, and UVVis spectral analysis definitively confirms the presence of silver nanoparticles through characteristic absorption peaks. Expanding the scope, the review delves into the assessment of antibacterial activity exhibited by the synthesized AgNPs. Initial findings suggest a comparable antibacterial efficacy to metal salt solutions, indicating the potential potency of AgNPs against gram-positive (Staphylococcus aureus) and gram- negative (Escherichia coli) microorganisms. Overall, this ongoing review significantly contributes to advancing our understanding of optimized synthesis techniques and the diverse applications of silver nanoparticles in the evolving landscape of nanotechnology.
