Fluorescent gold nanoclusters prepared in the presence of DNA
Abstract
Gold nanoclusters have been prepared using DNA as the stabilizer. The accompanying changes in the system at different components ratios have been discussed; the obtained products have been comprehensively characterized using a set of spectroscopy and microscopy techniques. Complexity of the underlying mechanism and the many-faceted role of DNA in the synthesis have been demonstrated. The obtained nanoclusters can serve as efficient homogeneous catalysts and in vivo biosensors.
