The antibacterial activity of samples prepared from waste lignocellulosic materials, namely wheat straw and maize stalks, doped with silver on their surface, was investigated. In order to use the various functional groups of these materials, Ag + was applied to the carrier by the adsorption method. EPR and SEM investigations demonstrated that Ag + ions were agglomerated into clusters of elemental silver on the carrier. The samples thus produced exhibited high antibacterial activity against
