A straightforward approach was developed for the synthesis of Pd, Pd-Fe2O3, Au-Fe2O3, and Au-Pd-Fe2O3 nanothermometers, using a single SL DNA. These NP-DNA conjugates were characterized using techniques including EDX measurements, ζ-potential of NPs before and after DNA functionalization, electron microscopy studies and fluorescence spectroscopy. The fluorescence studies of the NP-DNA demonstrate the interaction between the NP and the fluorophore, which is quenched in the case of Au-Pd-Fe2O3 NPs and is perhaps enhanced (when compared to AuNPs) in the case of Pd and Pd-Fe2O3 NPs.
