Integration of individual nanoparticles into desired spatial arrangements over large areas is a prerequisite for exploiting their unique electrical, optical, and chemical properties. However, positioning single sub-10-nm nanoparticles in a specific location individually on a substrate remains challenging. Herein we have developed a unique approach, termed scanning probe block copolymer lithogra...
Systematic studies on scanning probe lithography (SPL) methodologies have been performed using self-assembled monolayers (SAMs) on Au as examples. The key to achieving high spatial precision is to keep the tip-surface interactions strong and local. Approaches include three atomic force microscopy (AFM) based methods, nanoshaving, nanografting, and nanopen reader and writer (NPRW), which rely on...
In the past several years, much progresses have been made in the area of scanning probe based, parallel soft nano lithography for patterning biomolecule directly with nano-meter resolution and high degree of registration accuracy. We report the development and demonstration of arrayed soft nanolithography probes for dip pen nanolithography (DPN), scanning probe contact printing (SPCP), and mult...
Scanning probe instruments have expanded beyond their traditional role as imaging or "reading" tools and are now routinely used for "writing." Although a variety of scanning probe lithography techniques are available, each one imposes different requirements on the types of probes that must be used. Additionally, throughput is a major concern for serial writing techniques, so for a scanning prob...
To my beloved families. iv ACKNOWLEDGEMENTS First, I would like to thank my thesis advisor, Dr. Elisa Riedo, for providing me the opportunity to conduct this exciting research. I'm sincerely grateful for her valuable guidance and perpetual encouragement though my entire graduate research. and his group, for the fabrication of thermal cantilevers. their great help and support. v Finally, I would...
Scanning probe lithography (SPL) is applied to pattern fluid lipid membranes on a solid borosilicate substrate. Grids of metal lines, prepatterned onto the substrate by electron beam lithography, serve to partition the supported membrane into an array of isolated fluid pixels. By toggling the pH of the surrounding solution, the effect of the probe tip on the membrane can be regulated. Alkaline ...
The solution-phase self-assembly of bidentate 16-[3,5-bis(mercapto-methyl)phenoxy]hexadecanoic acid (BMPHA) on Au(111) was studied using nano-fabrication protocols with scanning probe nanolithography and immersion particle lithography. Molecularly thin films of BMPHA prepared by surface self-assembly have potential application as spatially selective layers in sensor designs. Either monolayer or...
