“…In this connection, the pulse laser ablation (PLAL) approach is an important physical method for producing nanostructures that has been demonstrated to be reliable and versatile [6]. Furthermore, more research needs to be done on the shape, structure, and media sensitivity of uniform and well-dispersed NPs produced inside of liquid suspension [7]. Due to its simplicity, costeffectiveness, and speed in reactive quenching of ablated species at room temperature, the (PLAL) technology has recently been acknowledged as a promising nanofabrication pathway [8].…”

Using a quick, easy, and effective one-step synthesis method called Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG)-pulsed laser ablation in liquid (PLAL), silver nanoparticles (NPs) are physically created. By using a pulsed laser at 532 nm to vaporize a metallic target (in this case, silver) submerged in deionized water, silver colloidal solutions are separately created. Laser parameters pulse of number (100, 200, and 300 pulse/sec) with constant ablation energy 500 mJ. The cubic crystalline structure of Ag particles was revealed by XRD, along with the formation of a pure cubic crystal structure of Ag particles and another cubic crystal structure attributed to AgO particles. The subsequent FESEM images showed the formation of highly spherical crystals (mean diameter 25.003 nm, 24.43 nm, and 9.75 nm ). UV-Vis analysis reveals the absorption band of Ag NPs at (407, 406, and 404 nm), and the energy gap was (2.74, 2,79, and 2.95 eV ) respectively. The diagnosis of spherical colloidal Ag-NPs was approved by FESEM, and the PL spectra show two peaks at 320 and 639 nm, confirming the purity of the produced Ag-NPs. It is clear that the possibility of using the prepared nanoparticle in optoelectronics applications such as optical detectors, solar cells, and optical sensors.

The biosynthesis of nanoparticles is a crucial research area aimed at developing innovative, cost‐effective, and eco‐friendly synthesis techniques for various applications. Herein, we synthesized copper oxide nanoparticles (CuNPs) using Couroupita guianensis flower extract via a simple green synthesis method. These green CuNPs demonstrate promising antimicrobial activity and anticancer activity against A549 nonsmall cell lung cancer (NSCLC) cells. We comprehensively characterized the CuNPs using UV spectrum, XRD, FTIR, SEM, and EDS analyses. The antibacterial and anticancerous performance is attributed to their spherical‐like morphology, which enhances effective interaction with bacterial and cancer cells. Moreover, CuNPs proved effective in inactivating Escherichia coli, achieving 2%, 52%, and 99% inactivation at 0, 30, and 60 min, respectively, and Listeria monocytogenes, achieving 1%, 48%, and 98% inactivation at 0, 30, and 60 min, respectively, under visible light. Furthermore, the CuNPs exhibited significant anticancer activity against A549 NSCLC cells, achieving cell viability reductions of 10%, 30%, 50%, 70%, 83%, and 91% at concentrations of 25, 50, 100, 150, 200, and 250 μg/mL, respectively. The green synthesized CuNPs demonstrate their potential in biomedical applications.
