The present work describes the development of a photoelectrochemical sensor based on titanium dioxide, cadmium telluride quantum dots and the tris (2,2′‐bipyridyl) ruthenium(II) chloride complex for detection of Isoniazid (INH). The Ru(bpy)32+/CdTe‐QDs/TiO2/FTO photoelectrochemical platform was characterized by scanning electrochemical microscopy, electrochemical impedance spectroscopy and amperometry. The photoelectrochemical sensor presented two linear ranges for INH concentrations ranging from 0.5 to 150 μmol L−1 and 150 to 1270 μmol L−1, with a theoretical detection limit of 0.02 μmol L−1. The sensor was successfully applied for the determination of INH in drugs samples used in the treatment of tuberculosis. [ABSTRACT FROM AUTHOR] |
