文摘
- •
Controlled synthesis of functional silica hybrid magnetic NPs by a single-step co-condensation process of APTES and TEOS in presence of SPIONs.
- •
Detailed characterization of the hybrid particles in terms of composition, size/morphology, surface, and magnetic responses.
- •
Controlled number of surface amino groups and magnetic properties of the hybrid particles by tuning the mass ratio of SPIONs and silanes (APTES/TEOS).
