Abstract

Abstract

En 中文
• A 3D hotspot SERS substrate based on AgNPs@SiO2@Fe3O4 curly slices has been developed. • The substrate is reusable, magnetically controllable and shows low LOD and high EF. • Its curly, open structure allows for more Ag NPs loading, enhancing hotspot effects. • Rolled morphology creates Z-axis hotspots, amplifying SERS signals.
