A Highly Charged Ag64+ Core in a DNA-Encapsulated Silver Nanocluster

Highly charged: Electrospray‐ionization mass spectrometry shows that single‐stranded oligonucleotide dC12‐encapsulated silver nanoclusters contain Ag64+ cores at basic pH values (see section of spectrum). The high positive charge of the cluster cores is presumably essential for preventing the multip...

Description
Summary:Highly charged: Electrospray‐ionization mass spectrometry shows that single‐stranded oligonucleotide dC12‐encapsulated silver nanoclusters contain Ag64+ cores at basic pH values (see section of spectrum). The high positive charge of the cluster cores is presumably essential for preventing the multiply deprotonated dC12 ligand from unfolding.
