In this work, new magnetic-plasmonic nanocomposites have been developed through the use of two complementary polyelectrolytes⁻polystyrene sulfonate (PSS) and poly(allylamine hydrochloride) (PAH). PSS, a negatively charged polyelectrolyte, was utilized as a stabiliser for magnetite nanoparticles, and PAH, a positively charged
