Abstract
A new fluorescence sensing system is developed based on the inner filter effect between conjugated polyelectrolyte-stabilized silver nanoparticles (P1-AgNPs) and 4-oxo-4-(pyren-1-ylmethoxy) butanoic acid (probe 1). This approach suggests that the detection limit for I− is as low as 0.3 nM (S/N=3). Interestingly, P1 revealed the novel role of CPE in the regeneration of AgNPs with smaller size.300
