Highly sensitive and selective colorimetric and plasmonic sensor of Fe2+ based on gold nanostructures biosynthesized with Opuntia joconostle fruit peel

Abstract Biogenic gold nanostructures have been obtained, for the first time, by bio-reduction of Au3+ ions with an aqueous extract of Opuntia joconostle fruit peel (Oj-AuNPs). This particular methodology is completely green, since room temperature was used, and no infusion preparation was required....
