In the area of designing chemical sensing materials, a major challenge is to find effective ways to increase sensitivity and selectivity and to lower detection limit. The rapid emergence of new or improved structural properties of nanostructured materials promises to address this challenge in many significant ways. The goals of this work are to develop effective strategies and methodologies for the design and fabrication of novel nanostructured materials using monolayer-capped gold nanoparticles as building blocks, and to explore the nanostructured chemical sensing properties. In addition to synthetic and preparation methods, an array of analytical techniques has been used in this work. We have determined the formation kinetics of molecularly-mediated thin film assemblies of nanoparticles. We have characterized the interparticle spatial properties of hydrogen-bonding mediated assemblies of nanoparticles. We have developed an effective route for the assembly of nanoparticle-carbon nanotube composite materials. Using chemiresistive and piezoelectric transducers, we have demonstrated that these nanostructured thin film materials exhibit highly-sensitive responses for the detection of volatile organic compounds and nitroaromatic compounds. By further coupling our nanostructured sensing array techniques with pattern recognition and theoretical modeling, we have gained new insights into the correlation of the nanostructured interparticle spatial properties with the sensor response characteristics. The combined results of our investigations have important implications for the design of novel nanostructured sensing arrays for portable or remote chemical detection with high sensitivity, high selectivity and low detection limit.
