[Dataset] Padina tetrastromatica-driven synthesis meets biopolymers: comprehensive profiling of starch nanoscaffolds infused with eco-friendly copper oxide nanoparticles

This dataset presents a detailed characterization of starch-based nanoscaffolds embedded with eco-friendly copper oxide nanoparticles (CuO NPs), synthesized using an aqueous extract of the marine brown alga Padina tetrastromatica. The green synthesis approach offers a sustainable and non-toxic alternative to conventional nanoparticle fabrication methods. To understand the physicochemical and morphological features of the developed nanoscaffolds, a suite of advanced analytical techniques was employed. UV–visible spectroscopy confirmed the formation of CuO nanoparticles through characteristic absorption peaks. FT-IR spectroscopy revealed the interaction between functional groups of the starch matrix and phytochemicals from P. tetrastromatica, highlighting their role in nanoparticle stabilization. X-ray diffraction (XRD) analysis demonstrated the crystalline nature of the CuO NPs within the scaffold. Scanning electron microscopy (SEM) provided insights into the surface topography and nanoparticle distribution, indicating uniform dispersion. Thermogravimetric analysis (TGA) evaluated the thermal stability of the nanoscaffolds, while dynamic light scattering (DLS) measured particle size distribution and colloidal stability. This dataset serves as a valuable resource for researchers focused on developing green nanomaterials for biomedical, environmental, or packaging applications, offering an eco-conscious platform for future innovations in sustainable nanotechnology.本数据集详细表征了以海洋褐藻四迭藻（Padina tetrastromatica）水提物合成的、负载环保型氧化铜纳米颗粒（CuO NPs）的淀粉基纳米支架。该绿色合成策略为传统纳米颗粒制备方法提供了一种可持续且无毒的替代方案。为探明所制备纳米支架的物理化学与形貌特征，本研究采用了一系列先进分析技术：紫外-可见分光光度法（UV–visible spectroscopy）通过特征吸收峰证实了CuO纳米颗粒的成功合成；傅里叶变换红外光谱（FT-IR spectroscopy）揭示了淀粉基质官能团与P. tetrastromatica植物化学成分之间的相互作用，阐明了其在纳米颗粒稳定过程中的作用；X射线衍射（X-ray diffraction, XRD）分析证实了支架内CuO纳米颗粒的晶体结构；扫描电子显微镜（Scanning Electron Microscopy, SEM）观测了支架的表面形貌与纳米颗粒分布情况，结果显示纳米颗粒分散均匀；热重分析（Thermogravimetric Analysis, TGA）评估了纳米支架的热稳定性；动态光散射（Dynamic Light Scattering, DLS）则测定了颗粒尺寸分布与胶体稳定性。本数据集可为致力于开发用于生物医学、环境或包装领域的绿色纳米材料的研究人员提供宝贵参考，为可持续纳米技术的未来创新搭建了兼具环保理念的研究平台。
