Congratulations to Dr Aquiles Carattino, who successfully defended his PhD thesis titled “Gold Nanorod Photoluminescence — Applications to Imaging and Temperature Sensing” on Thursday 9 March 2017 at Leiden University’s Academy Building in the traditional manner.

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.
