Abstract
The self-assembled gold nanoparticle film deposited from the liquid-liquid interface has been fabricated, and homogeneous surface-enhanced Raman scattering (SERS) of R6G molecules on the film has been observed. The SERS enhancement factor of the film is estimated to be in the range 108-1010. Occasionally, there are some sudden jumps in the Raman signal, where the signal is increased a few times. Such jumps are probably caused by single-molecule SERS in some extremely “hot” sites.
