Abstract
Abstract Nanoparticles with an average size of ~100 nm were obtained by ionic gelation of chitosan (M 6.5×103 and 60×103 Da) in the presence of tripolyphosphate. Dispersions of the nanoparticles showed high antimicrobial activity against pathogenic organisms such as C. michiganensis strain 101 bacteria and F. graminearum and A. solani fungi.
