Summary:Blue fluorescent gold nanoclusters were prepared in the presence of poly-cytosine DNAs at low pH and poly-adenine at neutral pH using citrate as the reducing agent; various buffer conditions affecting the synthesis have been explored. Tuning pH and DNA concentration has produced blue fluorescent gold nanoclusters using poly-cytosine and poly-adenine.
