Rutin-modified silver nanoparticles as a chromogenic probe for the selective detection of Fe³⁺in aqueous medium

Abstract

The use of rutin-modified silver nanoparticles for selective detection and sensitive quantification of Fe3+ in aqueous solution is described.

“…(g) Visual selectivity of rutin-AgNPs to Fe­(III) compared to other ions (concentration of selected metal cations is 10 mM). Reprinted with permission from ref . Copyright 2019, The Royal Society of Chemistry.…”

“…The addition of Fe­(III) ions then induced the coordination complex formation and consequently led to a combined aggregation/growth of rutin-AgNPs with a significant color-changing (for the schematic illustration of the involved mechanism, see Figure e,f). Visual selectivity of the rutin-AgNPs-based probe to Fe­(III) compared with other ions is demonstrated in Figure g …”

“…Visual selectivity of the rutin-AgNPs-based probe to Fe(III) compared with other ions is demonstrated in Figure 4g. 58 A FRET sensor was introduced via entering 3-hydroxyflavone as an acceptor into the hydrophobic cavity of β-cyclodextrin functionalized ZnS-QDs as a donor for sensitive detection of glucose (Figure 12-5a). 59 One of the disadvantages of 3hydroxyflavone is its reduced water solubility, which limits its applications in bioimaging.…”
