Rutin-modified silver nanoparticles as a chromogenic probe for the selective detection of Fe in aqueous medium.

The development of nanoprobes for selective detection of metal ions in solution has attracted great attention due to their impact on living organisms. As a contribution to this field, this paper reports the synthesis of silver nanoparticles modified with rutin in the presence of ascorbic acid and their successful use as a chromogenic probe for the selective detection of Fe in aqueous solution. Limits of detection and quantification were found to be 17 nmol L and 56 nmol L, respectively.
