Design of Core@Shell Nanoparticles Based on Gold and Magnetic NiFe Prussian-Blue Analogues Featuring Shape-Dependent Magnetic and Electrochemical Activity.

ABSTRACT: Au@Prussian-Blue analogue (PBA) core@shell nanoparticles (NPs) are highly versatile nanostructures with complementary and shape-dependent properties of interest in the current technologies. However, due to the high reactivity of cyanides toward Au, scarce PBAs have been successfully synthesized in direct contact with Au NPs, leaving the formation of anisotropic Au@PBA NPs as a significant synthetic challenge. Here, we have developed a robust protocol for synthesizing core@shell NPs, composed of a magnetic CsNi[Fe(CN)₆] PBA shell grown on individual Au NPs, regardless of the core morphology (spheres, rods, or stars). Specifically, the uniqueness of our protocol lies in the prior Au core functionalization with anchoring molecules that facilitate PBA growth while preventing Au etch
