Rapid one-pot synthesis of MMTA protected fluorescent gold nanoclusters for selective and sensitive detection of ferric ion

A novel fluorescent gold nanoclusters have been successfully obtained employing MMTA as both reducing and protecting agents with a short time of 20 min. The MMTA-AuNCs were exploited for sensitive and selective detection of Fe3+ ion. In addition, the as-fabricated fluorescent sensing system was successfully applied to the analysis of Fe3+ in water and serum samples with satisfactory recoveries.216
