Scheme 2.

Scheme 2.

Graphical representation of one possible mechanism for acid-mediated nitric oxide (NO•) donation characteristics from a diazeniumdiolate form of brominated carbon nanodots (BrCND). For this schematic, NO• is generated by BrCND after acid cycling. The products generated restore the original structure. In the absence of competing pathways, NO• may react with the BrCND to restore the diazeniumdiolate.
