The new specific metal sensors for copper, zinc, nickel, cobalt, iron, arsenic, antimony, bismuth, vanadium, molybdenum, selenium, and lead were synthesized by using N-phenyl[1,2 methane fullerene C60]C61 complexes. The metal sensors were characterized by pH range, electrode response, response time, and associated metals. The limit of detection of the sensors was found to range between 3×10-7 and 5×10-7, with lifetime between 6 and 8 months. These metal sensors were used for the detection and quantitative determination of trace metal impurities in drugs and pharmaceuticals.
