Gold nanoclusters are plasmonic materials that offer a number of attractive photophysical properties. DNA-gold hybrid nanoclusters are currently being developed for a number of applications including enhanced enzymatic reduction of oxygen. Currently, the N3 acceptor site of pyrimidine rings, specifically the N3 acceptor site of cytosine, is thought to play an important role in DNA-gold binding.  Here, we use Raman spectroscopy to describe the binding interactions between the gold atoms and different nucleobases in hybrid DNA-gold nanoclusters in order to understand how DNA and gold affect each other’s properties.<br/> <br/>
