Green Synthesis of Silver Nanoparticles Using Sulphated Polysaccharides from Gracilaria tenuistipitata

Abstract

The invention presents an environmentally friendly method for producing silver nanopartic1es (AgNP) using sulfated polysaccharides from G. tenuistipitata. This green synthesis approach eliminates the need for harmful chemicals, making it suitable for a wide range of industrial, biomedical, and environmental uses. The resulting AgNPs are stable, uniform in size, and show significant bioactivity. Advanced characterization techniques, such as UV-Vis spectroscopy, FT-IR, FE-SEM, EDX, and XRD, confirm the nanopartic1es' high stability and bioactivity, highlighting their potential for various applications without relying on hazardous substances.
