Self-Assembly for Nanomanufacturing of Hybrid
Physics, Seoul National University, Korea

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 are utilized to functionalize the desired solid substrate area with
organic molecules, and nanostructures (e.g. nanoparticles , carbon
nanotubes , 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
prospect and possible applications of hybrid devices also will be discussed.
