[Dataset] Eco-conscious biomaterial design: Analytical insights into starch nanoscaffolds with green-engineered copper oxide nanoparticles using marine Sargassum wightii extract

This dataset presents a detailed physicochemical characterization of starch-based nanoscaffolds integrated with copper oxide nanoparticles (CuO NPs) synthesized via an eco-friendly approach using Sargassum wightii, a marine brown algal extract. UV-visible spectroscopy (UV-Vis) confirms CuO NP formation through characteristic plasmon resonance peaks, while Fourier-transform infrared spectroscopy (FT-IR) identifies bioactive compounds (e.g., polyphenols, polysaccharides) in the algal extract responsible for nanoparticle reduction and stabilization, alongside interactions (e.g., hydrogen bonding) between starch polymers and CuO NPs. X-ray diffraction (XRD) validates the crystalline phase and structural purity of the nanoparticles, and scanning electron microscopy (SEM) reveals the nanoscaffold’s porous architecture, surface topography, and homogeneous CuO NP dispersion. Thermal gravimetric analysis (TGA) demonstrates enhanced thermal stability and delayed degradation of the nanocomposite, attributed to nanoparticle reinforcement. Dynamic light scattering (DLS) profiles hydrodynamic size, polydispersity, and colloidal stability of the CuO NPs, critical for assessing biocompatibility.
The study emphasizes the sustainable synergy between Sargassum wightii’s phytochemicals and starch matrices, yielding scaffolds with improved mechanical strength, thermal resistance, and controlled biodegradation. These nanohybrid systems hold promise for eco-conscious biomedical applications, such as tissue engineering, wound healing, or drug delivery, where low environmental impact and high performance are prioritized. By merging green nanotechnology with advanced analytical workflows, this dataset bridges marine bioresource valorization with material innovation, offering a scalable strategy for eco-friendly biomaterial development. Researchers can leverage these insights to optimize algal-mediated synthesis protocols, tailor scaffold porosity and crystallinity, and validate the ecological and functional advantages of marine algae-derived nanocomposites. The work underscores the potential of Sargassum wightii in advancing circular economy principles, reducing reliance on toxic chemicals, and fostering sustainable alternatives in nanotechnology-driven biomaterial design.
