Abstract
(Gram-positive). The mound structure and antibacterial activity in the modified PP NWFs disappeared upon washing with a polar organic solvent. After washing, nanoparticles of around 80 nm in diameter were observed in the solution. The results of several mechanistic studies suggest that nanoparticles can contribute to the antimicrobial activity of oxidised PP NWFs.
