dcterms:description
Silver nanoparticles (NPs) are due to their unique optical, catalytic and biological properties of the widespread use not only in research laboratories, but also in common practice. Methods of silver NPs preparation are mostly based on the reduction of soluble silver salt using suitable reducing agent. In the case of modified Tollens reaction is ammonia complex of silver reduced by sugar. The presence of complexing agent allows together with a selection of reducing sugar and pH modification of the size and morphology of the prepared silver NPs. In presented study the size of the prepared silver NPs was varied from 25 to about 75 nm by this way. Silver NPs prepared by modified Tollens reaction show high antibacterial activity and a significantly low cytotoxicity. Prepared silver NPs also proved particularly high catalytic activity which was tested in the reduction of nitro compounds and organic dyes, the substances that show a high degree of environmental toxicity.
