| The understanding of the unique electrical and optical properties of nanoparticle-structured materials and their correlation with the interparticle properties of the nanostructured assemblies are important for developing chemical/bio sensing applications. With our capabilities both in synthesizing highly-monodispersed gold nanoparticles and in assembling thin films of the nanoparticles by molecularly mediators, we have prepared high-quality thin films of molecularly-linked nanoparticles with controlled particle size and interparticle spatial properties. Systematic measurements of the electrical conductivity and optical properties of the thin film assemblies were carried out. The results have led us to the establishment of the correlation between the interparticle linking molecular length in the nanoparticle thin films and the electrical/optical properties. The findings have significant implications to the design and fine-tuning of the nanostructured thin films as novel sensing materials. |
