A novel fundamental understanding of the features of mechanism for the synthesis of luminescent silver nanoclusters (AgNCs) in human hemoglobin (Hb) as capping/reducing agents is presented based upon simultaneous size transition and fluorescence enhancement phenomena  The interesting features consis...
