Abstract

original image

Superparafragilistic: An amorphous seed-mediated strategy has been developed for the synthesis of hybrid nanoparticles (see images) that are composed of silver (yellow) and iron oxide (blue) nanodomains and exhibit unique optical properties. These properties originate from both the strong surface plasmon resonance of the silver and the strong superparamagnetic responses of the iron oxide nanodomains.
