Final Report Abstract

Inofeo is a project dealing with the use of nanocontainers, zeolites L, as interfacing tool to the external word. The zeolites possessing 1D nanoscale channels, filled with molecules, or chemically functionalized, provide an unprecedented level of control for interfacing molecules and nano-objects. The entire nanocontainers are organized and manipulated in both static and dynamic configurations. The project has 3 main objectives that combine the nanocontainers and the properties of the molecules entrapped in their channels and in particular optical, electrical and magnetic properties have been studied. We have demonstrated that very large magnetoresistance can be generated by organizing in 1D wires conductive molecules in the narrow channels of the zeolites. Also we have demonstrated that the nanocontainers can be manipulated in microfluidic devices and upon changing the direction of the flow a variation of the optical properties can be observed.
