Fast and sensitive dye-sensor based on fluorescein/reduced graphene oxide complex.

We report on a fast, sensitive, label-free, and general dye-sensor platform for synthetic organic dyes detection by competitive adsorption on reduced graphene oxide (rGO) against a fluorescent dye (FD). Fluorescein (Fl) as fluorescence indicator and a cationic dye methylene blue (MB) as model analyte were employed to investigate the analytical feature of… CONTINUE READING
