Title

FACILE SYNTHESIS OF L-CYSTEINE FUNCTIONALIZED GRAPHENE QUANTUM DOTS AS FLUORESCENT SENSING PROBES FOR ZN2+ IONS DETECTION

Abstract

In recent years, carbon based nanomaterials have generated new research interest in detection of micrograms quantities of metal ions and in bio-fluorescence imaging and sensing. Graphene quantum dots have gained immense importance due to their facile synthesis, low toxicity and aqueous solubility. Graphene quantum dots are getting the tremendous attentions because of their unique key properties like tunable photoluminescence, high photostability, biocompatibility and small size. In present work, graphene quantum dots are prepared by a simple and green pyrolysis method employing ethylene glycol as carbon source, L-Cysteine as functional molecule. These functionalized grapheme quantum dots are used as fluorescence sensing probe for detection of Zn2+ in µM concentration. This fluorescence sensor is evidence of Zn2+ due to the prominent fluorescence quenching. The interference of diverse ions is studied. Optimum pH is found to be at 7. This is a simple and very sensitive method for detection of Zn2+ ions in environmental samples.

Key Words

Graphene quantum dots, L-Cysteine, functionalized, fluorescence sensing probe, ethylene glycol and Zn2+ ions.
