Dip Pen Nanolithography: Nanofabrication and Nanoscale Assembly - Top Down Nanostructures and Bottom Up Nanobio

摘要

Precision nanoscale deposition is a fundamental requirement for much of current nanoscience research. Further, depositing a wide range of materials as nanoscale features onto diverse surfaces is a challenging requirement for nanoscale processing systems. Dip Pen Nanolithography (DPN) is a high resolution scanning probe-based direct-write technology emerging as a promising solution for these requirements. It is fundamentally a bottom up nanoscale deposition technique (i.e. templated assembly); however, direct-write with etch resist "inks" leads to a powerful form of top down nanofabrication. NanoInk's platform system, the NSCRIPTOR, is an instrument and software package enabling nanoscale registry and alignment, sophisticated CAD design, and high quality AFM imaging. To support this, NanoInk has developed chemical ink libraries, MEMS pen systems for serial and massively parallel printing, and selective ink delivery systems.
