This work describes a method for the determination of 1-hydroxypyrene (OH-Py) via aggregation-induced quenching of the emission of protamine-coated gold nanoclusters using 9-hydroxyphenanthrene (OH-Phe) as a sensitizer to boost the emission efficiency of nanoprobe. Under optimum conditions, the drop in fluorescence intensity at excitation/emission wavelengths of 300/596nm is proportional to the concentrations of OH-Py in the range from 1.0 to 65nM. The relative standard deviations are 4.2, 2.4 and 1.9% (for n= 11) at concentration levels of 8.0...
