Study of fabricating functional nanostructure through combined with molecular assembly

In any way, it is difficult to fabricate a functional nanostructure, especially for the research and development of devices. Arranging atoms, molecules to establish a device structure, named the way of bottom-up, represents a direction along which might be with the advantages of low-cost, easy to control and flexible for forming the structure. At present molecular assembly has been found the very important role in the way of bottom-up. The combination of molecular assembly and other fabrication techniques, e.g., lithography, is the first stage of the bottom-up to fabricate the functional structures of devices. Herein we present our efforts to make the electrodes with the feature of nanogap, the preliminary results of the arrangement of nanoparticles within the gap of the electrodes and the assembly of biomolecules on the surface of the electrode.
