Semiconductor nanoparticles based on II-VI materials are challenging to develop chemical sensor materials for biomedical and environmental applications. Highly luminescence CdTe nanoparticles were synthesized in a coprecipitation route using aqueous salt solutions and with different thiols as stabilizers. The synthetic procedure is simple, efficient, and stable. It could also allow for controlling the particle size by varying the experimental conditions such as reaction time and pH values. Strong luminescence of the nanoparticles was observed under UV-excitation and emission colors could be adjusted. Triethylenetetramine (TETA) is a candidate treatment for diabetic cardiovascular complication because of TETA’s ability to remove excessive extracellular copper. TETA is a selective copper chelator that has been used in the treatment of Wilson’s disease; it can reverse diabetic heart failure in diabetes. The interaction between CdTe nanoparticles and TETA was investigated by fluorescence spectroscopy. Based on the quenching effect of CdTe by TETA, a simple assay system for triethylenetetramine was developed. The preliminary results show that CdTe QDs can be used for the quantitative analysis of TETA in urine samples.
