Salicylazine activated plasmonic silver nanoprisms for identification of Fe(ii) and Fe(iii) from aqueous solutions

Herein, we report the synthesis and characterization, along with the successful application, of silver nanoprisms for the identification of Fe(ii)/Fe(iii) at the nanomolar level. A few real samples have also been analyzed successfully. The scanning electron microscopy (SEM)-transmission electron microscopy (TEM) imaging of the sensing events indicate analyte induced changes in the morphology and geometrical pattern of the silver nanoparticles.
