ZnO@graphene oxide core@shell nanoparticles prepared via one-pot approach based on laser ablation in water

Biodegradable Polymer Nanosheets Incorporated with Zn-Containing Nanoparticles for Biomedical Applications

“…In this study, we prepared Zn-containing NPs by LAL of Zn in chloroform or water, aiming at obtaining ZnCl2 and ZnO NPs, respectively. While laser ablation of metallic Zn in water is known to result in zinc oxide or/and hydroxide NPs [15,17,18,23,26,28,29,31], LAL processing of Zn plate in chloroform was not reported before. Chloroform was chosen as reaction medium for LAL for two reasons: (i) because ZnCl2 based NPs were expected, and (ii) because chloroform was then used as solvent for spin-coating of PLLA NSs without the necessary to centrifuge produced NPs and redisperse them in chloroform.…”

In this approach, laser beam is typically focused on a solid target, its pulses ablating the target and producing various nanostructures whose morphology, size and chemistry depend on the laser pulse parameters and liquid medium [14][15][16][18][19][20][21]25,29,30].…”

As a preparative method, LAL is attractive for several reasons: (i) it is an easy-to-use and green technique consuming minimum chemicals; (ii) a wide variety of nanostructures can be prepared, with control over their composition and morphology; (iii) the method operates at nominally room temperature while can often generate unique phases and morphologies.…”

Black Au-Decorated TiO2 Produced via Laser Ablation in Liquid

“…Laser ablation in liquids (LAL) has emerged as a promising high-performance and green approach for nanomaterial preparation. − When compared with wet-chemistry methods, LAL represents a simple and environmentally friendly technology that can be performed under normal environmental conditions without external stimuli. Intense pulsed laser radiation generates extremely high local pressures, temperatures, and quenching rates, thus providing experimental conditions for production of nanostructures with different phase composition (including unique metastable phases), , complex chemical composition, and morphology. − However, so far only a few studies reported on LAL-generated hybrid nanomaterials where plasmonic and dielectric counterparts were combined within practically relevant design, ,− yet without rigorous assessment of their nanophotonic properties and practical applications.…”

“…In this technique, the laser beam has been employed for material synthesis based on the high intensity of the laser beam at the focusing condition, which was sufficient to remove tiny particles from the surface of ablated target due to the high pressure and temperature of the forming plasma plume inside a liquid medium, followed to form colloidal nanoparticles (NPs) suspended in the liquid media (Mostafa & Mwafy, 2020a;Mostafa, Mwafy, Awwad, & Ibrahium, 2021;Mostafa, Mwafy, Awwad, & Ibrahium, 2021b;Mwafy, Gaafar, Mostafa, Marzouk, & Mahmoud, 2021) (Mostafa & Mwafy, 2020b). Shankar et al prepared ZnO@ graphene oxide via one-pot PLAL (Shankar et al, 2020). In 2021, Mostafa et al prepared ZnO NPs via nanosecond PLAL to form a nanocomposite structure with CNTs for water treatment (Mostafa, Mwafy, & Toghan, 2021) and PVA matrix for optoelectronic applications (Mostafa, 2021b).…”
