Summary

A plant-based water filter using Moringa oleifera seed protein as an affinity-based medium demonstrated high removal efficiency for various nanoparticles including metal oxides and polystyrene particles. The natural material offers a low-cost, biodegradable alternative to synthetic filtration systems for nanoparticle-contaminated water.

Water treatment plants offer the opportunity to reduce the exposure of humans to nanoparticle contamination. An affinity-based filter made from natural materials and Moringa oleifera seed protein achieves high removals of various nanoparticles.
