A new synthetic route for the preparation of strongly fluorescent gold nanodots (GNDs) through galvanic replacement is developed. The resultant GNDs show excellent photoluminescence properties with high photo-, time-, metal- and pH-stability. The as-prepared GNDs exhibit good dispersion in aqueous solution, favorable biocompatibility, and could be used as nanoprobes for cells.
