Fibers coated with nanoparticles have diverse applications as catalysts, biosensors, tissue scaffolds, and adsorbents for contaminants in water purification. However, current fabrication techniques employ multistep processes that often result uneven nanoparticle coatings, consequently leading to reduced activity. Here we present a single-step microfluidics-based approach the generation of microfibers uniformly nanoparticles. Inside microfluidic device, magnesium oxide (MgO) are deposited onto poly(vinylidene fluoride) (PVDF) polymer solution jet is solidifying into fibers through solvent evaporation. The formed display uniform coating on their surfaces, which crucial requirement all applications. Using these purification, demonstrate single adsorbent MgO can effectively remove multiple heavy metal contaminants, including As(III), As(V), Pb(II), Cd(II), both As(III) As(V) together. Remarkably, nanoparticles, when fibers, shown higher contaminant removal efficiency than used alone, arguably due greater surface area available form. developed technique could possibly be fabricate various other nanomaterial (nanorods, quantum dots, proteins) array
