Layer by layer polyelectrolyte encapsulation of satellite structured Fe3O4@SiO2-Au magnetic SERS probe for selective detection of food dyes

Sun Z., Jing C., Chinese Academy of Sciences, CN

In situ detection and identification of dyes from a complex chemical mixture presents a great challenge to analytical chemists. Au NPs were uniformly deposited on magnetic Fe3O4@SiO2 bead to form a core-satellite Fe3O4@SiO2-AuNPs (FSPA) hetero-nanostructure, [...]
