<p>Using hot charge carriers far from
a plasmonic nanoparticle surface is very attractive for many applications in
catalysis and nanomedicine, and will lead to a better understanding of
plasmon-induced processes, such as hot charge carrier or heat driven chemical
reactions. Herein we show that DNA is able to transfer hot electrons generated by
a silver nanoparticle over several nanometers to drive a chemical reaction in a
molecule non-adsorbed on the surface. For this we use 8-bromo-adenosine introduced
in different positions within a double stranded DNA oligonucleotide. The DNA is
also used to assemble the nanoparticles into superlattices enabling the use of
surface enhanced Raman scattering to track the decomposition reaction. To prove
the DNA mediated transfer, the probe molecule was insulated from the charge carriers
source, which hindered the reaction. The results indicate that DNA can provide
an attractive platform to study the transfer of hot electrons, leading to the
future development of more advanced plasmonic catalysts. </p>
