Temperature-tunable plasmonic property and SERS activity of the monodisperse thermo-responsive composite microgels with core-shell structure based on gold nanorod as core

- Monodisperse thermo-responsive composite microgels based on gold nanorod as core were fabricated.
- The plasmonic property of the composite microgels is notably dependent on temperature.
- Their SERS activity for the analytes of low affinity toward metal can be modulated by temperature.
