A novel oligothiophene-based colorimetric and fluorescent “turn on” sensor for highly selective and sensitive detection of cyanide in aqueous media and its practical applications in water and food samples

[Display omitted] •A new oligothiophene-based naked-eye colorimetric and fluorescent turn-on sensor 3TT was developed.•3TT exhibited high selectivity and sensitivity for rapid detection of CN−.•The low detection limit of sensor 3TT for CN− is 39.9nM.•3TT-based test strips were used to efficiently de...
