We are proud of our recent publication on single-molecule electrochemistry using enhanced fluorescence as readout.

At both ends of the nanorod (yellow), the incoming electromagnetic field of light is amplified by a factor 300 (red spots). If a molecule (blue dots) is situated there, its fluorescent signal is gets 500 times stronger.
We used gold nanorods as nanoatennas to reveal single-molecules of a redox sensitive dye, Methylene Blue, and studied the electrochemical properties of this molecule one by one.
