A novel high selective and sensitive fluorescent-colorimetric sensor have been developed for the determination of Pb2+ ions based on an ultrasound-assisted nano thieno[2,3-b]thiophene-2,5-dicarboxaldehyde-based Schiff base (H2L). A silica-based portable probe was fabricated via spin coating of H2L on a glass slide with diameter of 64 nm which has been applied in real sample successfully. The probe has been exploited as a dual chemosensor to detection lead ions in aqueous media with a detection limit ...
