| 제목 | Dip-Pen Nanolithography of Conducting Polymers |
| 초록 | Dip-pen nanolithography (DPN) is a promising new nanofabrication tool, which allows one to pattern molecules on a variety of surfaces with a coated AFM tip in a controlled fashion on the sub-100 nm to many micrometer length scale.1 Chemisorption of the ink to the underlying substrate is typically used as a driving force for moving the molecules from the tip to the substrate. Much of the work thus far has been done with the "thiol ink-gold paper"combination. However, recent work has demonstrated that DPN can be used with a variety of new combinations, including silazane inks-with oxide semiconductor substrates, metal salt or monomer inks on electrically biased semiconductors, functionalized oligonucleotides (DNA) on gold or monolayer-modified gold or oxide substrates, and optical dyes on glass by physisorption. In this study, we explore the potential for using electrostatic interactions as a driving force for the DPN process in order to pattern nanostructures of conducting polymers on modified silicon substrates. we report the deposition of nanoscale conducting polymer patterns on semiconductor surfaces using DPN.2 Significantly, we show that electrostatic interactions between water soluble ink materials and charged substrates can provide a significant driving force for the generation of stable DPN patterns on semiconductor surfaces. Characterization of the patterned conducting polymers was performed by LFM and electrochemical methods, the results of which are fully consistent with the conclusion that conducting polymer molecules can be successfully transported from the tip to these types of charged surfaces. 참고문헌 1.
