The present disclosure provides a bimetallic nanostructure with stimuli-responsiveness, including: a metal seed; a nanogap including a dopamine-modified stimuli-responsive copolymer attached to only a portion of the metal seed; and a metal shell surrounding the nanogap. The bimetallic nanostructure has a controllable interior nanogap, and may be used as a surface-enhanced Raman scattering (SERS) nanoprobe with improved SERS signals by virtue of the presence of the interior nanogap.
