DNA-templated fluorescent silver nanoclusters (Ag NCs) composed of several or tens of atoms are gaining much interest because of their unique properties and convenient emission tunability by DNA sequence and length. However, the modulation by other factors other than DNA is also dependent on the special DNA secondary structure formation such as i-motif or G-quadruplex that is stimulated by pH or K+. One main observation considered in this work is emission modulation of Ag NCs by divalent Mg2… CONTINUE READING
