摘要

We present a SERS-active gold nanostructure with built-in electromagnetic hotspots formed by densely packed gold nanoparticles on a gold nanorod. Cy3 labeled stimuli-responsive DNA motifs were introduced to the SERS-active nanostructure. The SERS signals can be switched ON and OFF reversibly in response to external stimuli (pH, metal ions or organic molecules).
