Abstract

The simple, fast, efficient route and eco-friendly synthesis of silver nanoparticles (Ag-NPs) using the marine-algae Padina pavonica (PP) extracts. The heat bio-reduction process involves using PP extract mediated to synthesize silver (Ag) nanoparticles (NPs). The PP extract provides an eco-friendly, low-cost, and safer alternative to traditional chemical and physical methods. The GC–MS results detect GLYCERYL TRIDODECANOATE, DODECANOIC ACID, and 1,2,3-PROPANETR dominantly examined majorly play a role in synthesizing the Ag-NPs. The synthesized PP-mediated NPs were denoted as PPAg-NPs and characterized the structural and morphological properties by UV–vis spectroscopy, XRD, SEM, HRTEM, EDS, DLS, and FT-IR. The 16S rDNA technique confirmed 6 (n = 6) human pathogens (HPs) strains were used for the antimicrobial study. Green synthesized PPAg-NPs showed a maximum and minimum inhibition growth zone of 16 mm in Escherichia coli, and 10 mm in Bacillus subtilis. The study result suggested the PPAg-NPs act with high efficiency and display greater sensitivity for antibacterial material depending on the concentrations. The synthesized green PPAg-NPs investigated the photocatalytic degradation of methylene blue (MB) dye. The highest 90 % efficiency was achieved under UV-light treatment within 105 min. The study’s outcome indicates that PPAg-NPs exhibit a strong antimicrobial efficacy toward HPs and MB decolorization that contributes to water cleansing, healthcare, and biomedical industries.

作为可持续资源的海藻绿色熔融纳米粒子：对人类病原体的抗菌活性和亚甲基蓝（MB）染料的光催化降解研究

利用海洋藻类 Padina pavonica（PP）提取物合成银纳米粒子（Ag-NPs）的方法简单、快速、高效且环保。热生物还原过程包括使用 PP 提取物介导合成银（Ag）纳米粒子（NPs）。与传统的化学和物理方法相比，PP 提取物是一种环保、低成本和更安全的替代品。气相色谱-质谱（GC-MS）检测结果表明，在合成 Ag-NPs 的过程中，乙二醇三烷酸酯（GLYCERYL TRIDODECANOATE）、十二烷酸（DODECANOIC ACID）和 1,2,3-PROPANETR 发挥了主要作用。通过紫外可见光谱、XRD、SEM、HRTEM、EDS、DLS 和 FT-IR 对合成的 PP 介导的 NPs 的结构和形态特性进行了表征，并将其命名为 PPAg-NPs。16S rDNA 技术确认了 6 株（n = 6）人类病原体（HPs）用于抗菌研究。绿色合成的 PPAg-NPs 对大肠杆菌和枯草芽孢杆菌的最大和最小抑菌生长区分别为 16 毫米和 10 毫米。研究结果表明，PPAg-NPs 具有很高的抗菌效率，并根据浓度的不同显示出更高的抗菌灵敏度。合成的绿色 PPAg-NPs 研究了亚甲基蓝（MB）染料的光催化降解。在紫外光处理下，105 分钟内的光催化效率达到最高的 90%。研究结果表明，PPAg-NPs 对 HPs 和 MB 脱色具有很强的抗菌功效，有助于水清洁、医疗保健和生物医学行业的发展。
