These include nanoscale biological sensors and protein motor-based nanomechanical systems. 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 are utilized to functionalize the desired solid substrate area with organic molecules, and nanostructures (e.g. carbon nanotubes, nanoparticles, proteins etc.) in the solution are specifically assembled onto the functionalized area via molecular recognition mechanism. In this presentation, we will discuss about 1) new properties of hybrid nanostructures and 2) important scientific issues related with the surface-templated assembly process.
