Hydrogen bonding and π-π interactions between AG-QDs and DNA at select binding sites. Green dotted lines show H-bonds between AG-QDs and basic groups, purines and pyrimidines. Yellow lines show π-π interactions between AG-QDs and basic groups (cytimidine, guanine, adenine, and thymine). Carbon, oxygen, hydrogen, and nitrogen are colored in grey, red, white, and blue, respectively
