This proposal aims at studying nanostructures and thin films of oxide semiconductors grown via hydrothermal synthesis assisted by microwave and deposited on different substrates in order to have great technological applications as biosensors, gas sensors, and nanogenerators. The synthesized materials have their morphological and structural properties characterized by atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy. The material is zinc oxide (ZnO) due to the functional properties of this oxide, in addition to being biocompatible. Movies of the nanostructures are grown directly on glass substrates, diamond and langasite during the synthesis process or will be synthesized and subsequently deposited by spin coating. The performance of live sensors (sensitivity, response speed, selectivity, stability) will be evaluated for sensitivity, biocompatible, conversion capacity (piezoelectric parameters).
