Abstract: Abstract The present invention relates to an environmentally friendly, sustainable, and scalable approach for the green synthesis of biofilm-targeted copper nanoparticles using •the combined aqueous extracts of the marine seaweeds Gracilaria edulis and Padina boergesenii. The complementary phytochemicals present in these seaweeds, including polyphenols, polysaccharides, flavonoids, terpenoids, phlorotannins, and other bioactive metabolites, act as natural reducing, stabilizing, and capping agents during nanoparticle formation, thereby eliminating the need for hazardous chemical reagents. The synergistic interaction between the phytochemicals enhances the physicochemical properties, stability, and biofilm-targeting capability of the synthesized copper nanoparticles. The biosynthesized nanoparticles are characterized using UV-Visible Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (EM), Dynamic Light Scattering (DLS), Zeta Potential Analysis, and Energy Dispersive X-ray Spectroseopy (EDX) to determine their structural, 'elemental, and morphological properties. The engineered nanopI articles exhibit broad-spectrum antibacterial activity against Gram-positive and Gram-negative bacteria, along with enhanced biofilm inhibition, antioxidant potential, and acceptable biocompatibility. Owing to these properties, the nanoparticles show promising applications in wound healing, antimicrobial coatings, Medical devices, pharmaceutical formulations, and environmental remediation. The invention provides a cost-effective, sustainable, and scalable platform for the development of multifunctional biofilm-targeted copper nanoparticles for biomedical, environmental, and industrial applications.
