This work exploits the magneto-optical activity of gold nanorods for the detection of sub-micromolar concentrations of glutathione using magnetic circular dichroism spectroscopy. Modulations of the magnetoplasmonic response of nanorods serve as the basis of the sensing methodology, whereby the presence of glutathione induces the end-to-end assembly of nanorods. In particular, the nanorod self-assembly enables a localized electric field in the nanocavities with adsorbed thiol molecules, whose fie ...[more]
