The formation and antibacterial activity of Zn/ZnO nanoparticle produced in Pometia pinnata leaf extract solution using a laser ablation technique

In this research, Zn/ZnO Nanoparticles (NPs) were prepared via the Pulse Laser Ablation (PLA) method using three liquids (Ethanol, Acetone, and Distilled Water). Zn/ZnO NPs were synthesized via an Nd-YAG laser with a wavelength of 1064 nm, applied energy of 800 mJ, a frequency of 6 Hz, and 100 laser pulses at room temperature. The Zn metal plate was dipped in Ethanol, Acetone, and Distilled Water, respectively. The UV-Vis results shows sharp and single peaks at 320, 341, and 333 nm for Zn/ZnO NPs in Ethanol, Acetone, and Distilled Water respectively. FTIR testing shows peaks at about 500 cm−1 for Zn/ZnO NPs in Ethanol, Acetone, and Distilled Water, which indicates Zn-O stretching vibrations. XRD investigation shows low-angle peaks at 23.31˚, 23.81˚, and 19.20˚ for Zn/ZnO NPs in Ethanol, Acetone, and Distilled Water, respectively. In addition, a sharp peak of high intensity was observed at 13.54˚ for Zn/ZnO Core/Shell NPs in Acetone. These peaks indicate that the structure is stable and undistorted. These patterns emphasize compact pore arrangements. The lower intensity of the gradient peaks indicates that ZnO formed at a preferred site. Nor did high-angle XRD patterns appear, indicating that the formed ZnO NPs are so small to be distinct from background noise or undetectable by widish angle XRD. The broad XRD peak at 2θ angles from 20° to 30° can also confirm that ZnO is low-crystalline. The TEM images show the presence of Zn/ZnO NPs in Ethanol, Acetone, and Distilled Water with a size of less than 50 nm, and TEM analysis confirms that the primary structure of Zn/ZnO NPs is a Core/Shell.

“…This means that the size of the Zn/ZnO NPs is very small. These outcomes match primarily in agreement with the literature [7,8,9,10].…”

“…At extreme conditions induced by high-power LAL of Zn in water (e.g., 1.7×10 11 W/cm 2 at λ=1064 nm and 8.3×10 10 W/cm 2 at λ=532 nm excitation), the high-pressure phase of W-ZnO and ε-Zn(OH) 2 composite nanocondensates is producible [251]. Summary of products obtained by LAL of Zn is shown in Table 8 [71,72,101,243,[251][252][253][254][255][256][257][258][259][260][261][262][263][264][265][266][267]. Ishikawa et al [254] reported that the growth of ZnO particles into columnar structures starts at temperatures higher than 60°C and becomes finely crystalized at 80°C.…”

“…This finding means that the Water + SDS (0.0001, 0.001, 0.01, 0.05, and 0.1 mol/L) 10 ns, 1064 nm, 10 Hz, 70 mJ/pulse air core-shell (AVG 18.1-44.5 nm) Zn@ZnO, Zn@Zn(OH) 2 [262] Water + chitosan (20 g/L) Natural resources are attaining increasing attention because of their bioaffinity and environmental friendliness. Yudasari et al [255] performed LAL of Zn in Pometia pinnata leaf extract (PPLE) solution and found that ZnO nanorods prepared in pure water transformed into smaller Zn/ ZnO spherical particles after adding PPLE, indicating the reduction and capping capacities of PPLE. Pure Zn NPs are obtainable in aqueous solutions containing chitosan biomolecules to inhibit oxidation [263].…”

“…Thermal treatment of LAL-synthesized ZnO and FeO x colloids allows the synthesis of ternary oxide (i.e., ZnFe 2 O 4 ) photocatalysts [277]. Benefiting from photocatalytic capacity, reactive oxygen species (ROS) generation, and internalization, LAL-synthesized ZnO [255], Zn/ZnO [255], and Zn@ZnO [255] colloids are also suitable for antibacterial applications. Successive LAL of Zn and Fe targets offers a good strategy to prepare antibacterial Fe-doped ZnO composites with a better performance than pure ZnO [278].…”

Diverse nanomaterials, in the forms of carbides, sulfides, oxides, metals, hydroxides, etc., have been synthesized by laser ablation in liquids (LAL) with metal targets as the dominant educts. Many advantages of LAL technique itself and its products have been revealed since 1983 when the first report about LAL was released. Different from traditional wet-chemical synthesis, one unique feature of LAL is its resultant extreme high-temperature and high-pressure local environment for the nucleation and growth of nanomaterials, despite being performed at room temperature. This extreme condition can induce the atomization and ionization of the target materials and liquid molecules to incur different chemical reactions. The laser, liquid, liquid additive, and target can significantly alter the local environment in a broad range. Thus, different phases and shapes of nanomaterials are producible even from the same target. Through directly comparing the products of LAL of 13 kinds of chosen representative metals synthesized under different conditions, this review presents and discusses current understandings, challenging issues, and perspectives related to the diversity of LAL-products, which is willing to promote a deeper investigation and discussion on a clear clarification of the chemical reactions and particle nucleation/growth processes.

“…A literature survey reveals that physico-chemical and biological properties of nanoparticles depend upon their size and shape. [1][2][3][4] Nanoparticles exert their antimicrobial action by binding to the surface of microbial cell membranes and altering their basic cellular functions. 5 Moreover, nanoparticles have been reported to penetrate the microbial cells and interact with nitrogen, sulfur and phosphorus of biomolecules.…”
