| Abstract |
Quantum sized metal nanoparticles have been continuously studied in recent years because of their promising property towards various applications. Among the various metal nanoparticles, nanoparticles composed of gold atoms have attracted wide attention in analytical sciences because they have unique optical and electrochemical properties but are not toxic.
Phenolic compounds used in medicals and industrials can be so harmful to human body, especially, to skin, liver and kidney. Therefore, the determination of phenolic compounds is clearly important. There are many analytical methods for determination phenolic compounds such as high performance liquid chromatography, capillary electrophoresis and fluorescence detection. But these methods have some limitations, requiring complex sample pretreatments and long analysis time.
In this study, the Au22SG18 nanocluster consisted of 22 gold atoms and 18 thiolate ligands has been synthesized and its electrogenerated chemiluminescence (ECL) properties have been characterized in order to detect phenolic compounds using amine compounds as co-reactant. In the present study, ECL of Au22SG18 nanocluster was generated in aqueous phase. In addition, highly efficient ECL quenching has been obtained in the presence of phenolic compounds. This experimental results have demonstrated the ECL of Au22SG18 nanocluster holding great promise for real analytical sciences.
