Direct readout SERS multiplex sensing of pesticides via gold nanoplate-in-shell monolayer substrate

- A general strategy for synthesizing anisotropic nanogold-in-shell at ambient condition has been proposed.
- A novel nanostructure, i.e., gold nanoplate-in-shell with high purity has been prepared.
- A highly active SERS monolayer substrate has been utilized for multiplex sensing of pesticides.
