Resumen:
Silver nanoparticles (AgNPs) have been synthesized, for the first time, using the pulp of Opuntia joconostle fruit as reducing reagent of Ag+ ions. The reported method is wholly green, since no temperature or infusion preparation were required. AgNPs with a 428 nm plasmon absorbance, a quasi-spherical morphology, a mean size of 17.7 nm, and an FCC crystal structure were obtained. These biogenic AgNPs, without further chemical functionalization, could sense easily (naked eye) and selectively the presence of Hg2+ ions in aqueous solution and in tap water. © 2022 Elsevier B.V.
