Original Abstract

Array of self-ordered Au QDs with tunable size (in the range of 10–30 nm) were successfully achieved via template based method. These QDs were composed of expected chemical elements with commonly occurring surface impurities such as carbon and oxygen. The fluorescence properties of Au QDs were found in the visible range of spectra with maximum position at about 370 nm and FWHM parameter of about 65 nm. The intensity of fluorescence significantly increased after adsorption of GSH molecules on Au QDs surface. This functionalization procedure enables further Au QDs array usage in biosensing, because GSH can serve as binding partner for detected analyte in the solution.
