A paper derived from an MSc thesis has been published in Macromolecular Rapid Communications, highlighting a green and sustainable approach to nanoparticle synthesis for water treatment applications.

The study presents a biogenic synthesis of silver nanoparticles using algal nanofibers (PAN/Cystoseira barbata) as a nanofibrous substrate, enabling uniform nanoparticle distribution and high reaction efficiency. Stabilization with xanthan gum (XG) provides excellent reusability, long-term stability, and prevents nanoparticle aggregation.

Beyond catalytic performance, the resulting PAN/Cb/Ag@XG nanofibrous material exhibits strong antimicrobial activity against E. coli and S. aureus. Its dual function—effective pathogen control without secondary pollution—makes it a promising eco-friendly solution for advanced water purification and disinfection systems.
