Eco‑friendly biosynthesis of gold nanoparticles from Amphimedon compressa with antibacterial, antioxidant, anti-inflammatory, anti-biofilm, and insecticidal properties against diseases vectors.

ABSTRACT: Gold nanoparticles (AuNPs) are increasingly recognized for their potential in biology due to their excellent drug delivery capabilities and ease of synthesis. To create AuNPs using marine sponge Amphimedon compressa, we used several techniques, including ultraviolet-visible (UV-visible) spectrophotometry, Fourier transform infrared (FTIR) spectrophotometry, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and x-ray diffraction (XRD). The UV-visible spectroscopy results demonstrated the formation of stable AuNPs at a pH of 7, with a peak absorption at 564 nm. FTIR spectroscopy indicated that secondary metabolites featuring -OH functional groups acted as reducing agents in the production of AuNPs. Morphological analysis showed that the AuNPs were spherical, consist
