| Abstract |
Afluorescence sensor for selective detection of cysteamine derived fromD-penicillamine capped cadmium sulfide quantum dots (DPA-CdS QDs) is proposed. The DPA-CdS QDs were successfully synthesized
via a simple method in a one-pot reaction. The morphology of DPA-CdS QDs was characterized by
transmission electron microscopy (TEM) revealing spherical shapes with an average size of 3.270.5 nm.
In the presence of cysteamine, the fluorescence intensity of the DPA-CdS QDs was enhanced proportionally with increasing cysteamine concentration. The proposedfluorescence sensor can be used to detect cysteamine in a wide range of working concentrations up to 10μM and with a limit of detection of
0.07μM. Furthermore, this sensor can be efficiently used for the detection of cysteamine in real urine
samples with high accuracy.
