- •
The monolayer film of Au@AgNR@PNIPAM composite microgels was formed by a dip coating method.
- •
The monolayer film on the silicon surface have high surface coverage, low surface roughness and high stability.
- •
The plasmonic property of monolayer film on the silicon surface still maintained the LSPR optical performance of Au@AgNRs.
- •
The monolayer film used as surface enhanced Raman scattering substrate is convenient for analysis and detection.
