Researchers use saffron waste as eco-finish for cotton

TEHRAN - Iranian researchers have developed a lab‑scale process that turns saffron waste into a dual‑function nanoparticle finish for cotton, claiming both greener chemistry and durable antibacterial performance.

The team used petals and stamens from Crocus sativus – normally discarded when saffron stigmas are harvested – as the sole reducing and stabilising agents to generate palladium–platinum (Pd/Pt) bimetallic nanoparticles directly on cotton.
