Study on electron beam (EB) irradiation of AgNO₃/chitosan/Diatomite (DA) suspension mixture was carried out. Influence of AgNO₃ precursor’s concentration on the size and the content of silver nanoparticles (AgNPs) deposited in DA was investigated. The TEM images demonstrated the AgNPs in nanocomposite of AgNPs/DA were spherical with an average diameter ≤10 nm at Ag⁺ concentrations from 2.5−10 mM. The antibacterial efficacy of AgNPs/DA against infectious pathogens for Tra catfish (Pangasianodon hypophthalmus) such as Aeromonas hydrophila and Edwardsiella ictaluri was evaluated.
