Optical and mass spectra of higher-order DNA constructs for silver clusters

Description
Silver clusters associate with DNA strands and form distinct chromophores. Silver nanoclusters consisting of ~10 atoms coordinate with DNA, and the DNA ligand tunes the cluster spectra. In this work, we discuss DNA templates with different sequences and structures. We use absorption and circular dichroism spectroscopies to measure the cluster spectra and mass spectrometry to measure the cluster stoichiometry. Our studies concentrate on the effect of DNA sequence on the cluster environment.
