Phosphorothioate DNA Mediated Sequence-Insensitive Etching and Ripening of Silver Nanoparticles
Many DNA-functionalized nanomaterials and biosensors have been reported, but most have ignored the influence of DNA on the stability of nanoparticles. We observed that cytosine-rich DNA oligonucleotides can etch silver nanoparticles (AgNPs). In this work, we showed that phosphorothioate (PS)-modifie...
