Recent dramatic progress of nanotechnology and biological science allows us to combine soft materials (e.g. biomolecules, self-assembled monolayer etc.) with solid nanostructures (e.g. nanoparticles, carbon nanotubes, electronic circuits etc.) to build a generation of new hybrid nanoscale devices such as molecular electronic circuits, nanoscale biological sensors, and protein motor-based nanomechanical systems. However, a major stumbling block for their industrial applications is a difficulty in high throughput assembly for device fabrication. One promising nano-manufacturing method for these hybrid devices is the surface-templated assembly process. In this strategy, direct deposition methods such as dip-pen nanolithography[1] are utilized to functionalize the desired solid substrate area with organic molecules, and nanostructures (e.g. nanoparticles [2], carbon nanotubes [3], proteins etc.) in the solution are specifically assembled onto the functionalized area via self-assembly mechanism. In this presentation, I will discuss about: 1) self-assembly-based nano-manufacturing methods for hybrid nano-devices and 2) new scientific issues related with hybrid nanostructures. Future prospect and possible applications of hybrid devices also will be discussed.
