Abstract
Sensors, sensing systems and sensing methods of the invention provide for detection of peroxides, including for example, vapor-phase HOand organic peroxides such as di-tert-butyl peroxide. A sensor and sensing method of the invention uses at least two phthalocyanines, one of which exhibits an oxidation reaction with peroxides and the other of which exhibits a reduction reaction with peroxides. A peroxide is readily identified by a sensor of the invention when one of the at least two phthalocyanines exhibits increased resistance to current flow and the other of the at least two phthalocyanines exhibits decreased resistance to current flow.
