Resumo
Nanoscale inorganic semiconductors (with interfacial thickness <10 nm) have superior stability compared to soft organic compounds and are important for the development of enhanced reagentless sensing devices. As a proof of concept, this study demonstrated that the density of states of a copper oxide mixed valence semiconducting nanoscale film can be suitably designed as a transducer signal for reagentless sensing of phenol.
