Glutenin-directed gold nanoclusters employed for assaying vitamin B1

Abstract

Various nanoclusters have been raised to sensing kinds of targets by virtue of their promisng fluorecent signals. Herein, the glutenin-directed gold nanoclusters (AuNCs@Glu) with the red-fluorescence have been originally synthesized. Meaningfully, the nanoclusters exhibited the multiple advantages including the favorable photostability, low-toxicity and stability. The groups of -COOH, -NH2, -OH, -C=O on the surfaces of AuNCs@Glu, facilitated the possible applications towards sensing. Thus, their abundant groups of carboxyl and hydroxyl of AuNCs@Glu enabled vitamin B1 to be adsorbed on the surfaces, leading to an obvious fluorescence quenching through the aggregations emerging. On the basis of this phenomenon, AuNCs@Glu were thereby applied for detecting Vitamin B1, and it achieved a linear range of 8-8000μm with the detection limit of 115 nM, which broadens the avenues of assaying vitamin B1.
