In this investigation, for the first time, we used (strawberry) leaf extract as a source of natural reducing, capping or stabilizing agents to develop an eco-friendly, cost-effective and safe process for the biosynthesis of metal-based nanoparticles including silver, copper, iron, zinc and magnesium oxide. Calcinated and non-calcinated zinc oxide nanoparticles also synthesized during a method different from our previous study. To confirm the successful formation of nanoparticles, different characterization techniques applied. UV-Vis spectroscopy, X-ray Diffraction (XRD) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-ray Spectroscopy (EDS), Photon Cross-Correlation Spectroscopy (PCCS) and Fourier Transformed Infrared Spectroscopy (FT-IR) were used to study the unique structure and properties of biosynthesized nanoparticles. The results show the successful formation of metal-based particles in the range of nanometer, confirmed by different characterization techniques. Finally, the presented approach has been demonstrated to be effective in the biosynthesis of metal and metal oxide nanoparticles.
在这项研究中，我们首次使用（草莓）叶提取物作为天然还原剂、封端剂或稳定剂的来源，开发了一种环保、经济高效且安全的方法，用于合成包括银、铜、铁、锌和氧化镁在内的金属基纳米粒子。煅烧和未煅烧的氧化锌纳米粒子也是在与我们之前的研究不同的方法中合成的。为了确认纳米粒子的成功形成，应用了不同的表征技术。使用紫外-可见分光光度法、X 射线衍射（XRD）光谱法、场发射扫描电子显微镜（FESEM）结合能谱（EDS）、光交叉相关光谱（PCCS）和傅里叶变换红外光谱（FT-IR）来研究生物合成纳米粒子的独特结构和性质。结果表明，通过不同的表征技术证实了金属基纳米粒子在纳米范围内的成功形成。最后，所提出的方法已被证明可有效用于金属和金属氧化物纳米粒子的生物合成。
