Encoding molecular-wire formation within nanoscale sockets and mass transport in single wall carbon nanotube.

摘要

Nanotechnology refers to a science that controls material at the atomic or molecular level. By combining the "top down" and "bottom up" approach, many nanoscale devices have been realized and shown novel performance.;In this thesis, two projects addressing molecular electronics and single polynucleotide molecule detection are described individually.;In the first section, a molecular device with chemical response is described. Two new techniques are developed for reliable molecular scale nanogap fabrication and in situ molecule modular assembly. As a result, we successfully encoded different chemical functionalities into nanogap devices, which would potentially be useful as a chemical or biological sensor.;In the second section, the experiments of using carbon nanotube as nanofluidic channel for molecule sensing and single strand DNA molecules translocation is described. This is particularly interesting because of its potential application in sequencing technology.
