Metal oxide nanoparticles are interesting building blocks for realizing films for a number of applications that include bio- and -chemical sensing. In the present work TiO2 nanoparticles have been used for a self-assembling procedure to realize lined-up micro-patterned titanium oxide films. The high surface-to-volume ratiomakes these structures suitable to adsorb gases. Morphological,compositional and structural characterization have been performed in order to determine the features of the assembling. The analysis of electrical behaviour of the ordered films in controlled atmosphere allowed us to test the gas sensing properties.

Abstract
Metal oxide nanoparticles are interesting building blocks for realizing films for a number of applications that include bio- and -chemical sensing. In the present work TiO2 nanoparticles have been used for a self-assembling procedure to realize lined-up micro-patterned titanium oxide films. The high surface-to-volume ratiomakes these structures suitable to adsorb gases. Morphological,compositional and structural characterization have been performed in order to determine the features of the assembling. The analysis of electrical behaviour of the ordered films in controlled atmosphere allowed us to test the gas sensing properties.File in questo prodotto:
