Abstract

Multifunctional fluorescent-magnetic pH-responsive eccentric-(concentric-Fe3O4@SiO2)@polyacrylic acid core-double shell nanocomposites (NCs) have been prepared for simultaneous cell imaging and pH-responsive drug delivery. To confirm the universality of the synthetic concept, the synthetic strategy was also extended to fabricate monodisperse eccentric-(concentric-NaYF4:Yb/Er/Gd@SiO2)@polyacrylic acid core-double shell NCs.
