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

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.
