The current study aimed at the synthesis of zinc oxide nanoparticles using water extracts obtained from two different seaweed species Halymenia venusta and Hypnea pannosa. Zinc acetate dehydrate was used as a precursor material in this study. Various characterization techniques were employed to (1) confirm the formation of ZnO nanoparticles (ZnO NPs) and (2) evaluate the morphological properties of the synthesized ZnO NPs such as size and shape. The scanning electron microscopy images of cube-shaped and flake-shaped were obtained for H. pannosa–mediated and H. venusta–mediated ZnO NPs, respectively. The size of the nanoparticles was measured to be 200 nm for Hy. pannosa–mediated ZnO NPs and 200–300 nm for H. venusta–mediated ZnO NPs. Furthermore, these green synthesized ZnO NPs demonstrated strong antibacterial activity against bacterial strains.

目前的研究旨在使用从两种不同的海藻 Halymenia venusta和Hypnea pannosa获得的水提取物合成氧化锌纳米颗粒。在这项研究中，脱水醋酸锌被用作前体材料。采用各种表征技术来 (1) 确认 ZnO 纳米粒子 (ZnO NPs) 的形成和 (2) 评估合成的 ZnO NPs 的形态特性，例如尺寸和形状。分别获得了H. pannosa介导和H. venusta介导的 ZnO NPs的立方体形和片状扫描电子显微镜图像。Hy的纳米粒子的尺寸被测量为200nm 。pannosa介导的 ZnO NPs 和 200–300 nmH. venusta介导的 ZnO NPs。此外，这些绿色合成的 ZnO NPs 对细菌菌株表现出很强的抗菌活性。
