Nano Gold-Graphene Oxide Nano Composite Compositions

The present invention relates to a nano gold–graphene oxide nanocomposite composition designed to synergistically combine the unique properties of gold nanoparticles and graphene oxide into a stable and multifunctional material system. The composite comprises uniformly distributed gold nanoparticles anchored onto a graphene oxide matrix through controlled interfacial interactions, resulting in enhanced optical, electrical, catalytic, mechanical, and biocompatible characteristics. The graphene oxide framework prevents nanoparticle aggregation while providing high surface area and functional groups, and the gold nanoparticles contribute superior catalytic activity, plasmonic behavior, and chemical stability. The proposed nanocomposite overcomes limitations of conventional nanomaterials such as poor dispersion, instability, and limited scalability. The invention is
adaptable for diverse applications including biomedical diagnostics and therapy, biosensing, environmental remediation, energy storage, catalysis, and advanced electronic systems. The composition supports scalable synthesis, tunable properties, and longterm stability, enabling effective industrial and commercial utilization.
