Environmentally sustainable route to SiO₂@Au-Ag nanocomposites for biomedical and catalytic applications.

ABSTRACT: A facile, sustainable, operationally simple and mild method for the synthesis of SiO₂@Au-Ag nanocomposites (NCs) using Nephrolepis cordifolia tuber extract is described and its catalytic, antibacterial and cytotoxic properties were investigated. The fabricated SiO₂@Au-Ag NCs were well characterized by UV-visible spectroscopy, transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), Fourier transform infrared (FT-IR) spectroscopy, powder X-ray diffraction (XRD), thermogravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) to determine the optical activity, size and morphology, elemental composition, functional groups present, crystallinity, thermal stability and chemical state respectively. The obtained SiO₂@Au-Ag NCs exhi
