Popis:	The fast emergence of various nanomaterials with characteristic properties has provided excellent tools in analytical sciences. Herein, environmental-friendly luminescent gold nanoclusters (AuNCs) were synthesized by using soy protein as template. We first investigated the optimum reaction condition for the brightest emission, and then employed the luminescent AuNCs to develop a visual sensor for the detection of Cu2+. This sensor showed good sensitivity and selectivity with a linear response of 40–400 μM and a detection limit of 10 μM. The assay was facile to operate and the optical results could be read by naked eyes under a portable UV light, showing great application potential in environmental, biochemical and food analysis.
