The video demonstrates how AFM is used to explore the structures of nanomaterials with advanced AFM modes and Park Systems’ Crosstalk Elimination (XE) technology.

As described in the article, researchers at Northwestern University’s International Institute for Nanotechnology, headed by Professor Chad A. Mirkin, have developed a new technique for printing nanoscale structures cheaply, quickly, and in large batches. The process, called Hard-tip, Soft-spring Lithography (HSL), combines the high resolution of scanning-probe nanolithography with the low cost and high throughput of contact printing methods.
 
In the HSL technique, an array of hard silicon tips set atop a cushioning polymer layer is used as a cheap, disposable “print head,” impressing thousands of identical bitmap images into an elastomeric substrate. Mirkin developed the technology with a Park Systems XE-150 atomic force microscope equipped with a unique tilting stage and an environmental chamber for humidity control.
 
In an exercise to demonstrate the high resolution and throughput of the method, an HSL-enabled XE-150 successfully duplicated 19,000 miniaturized images of the iconic pyramid on the reverse of the USD $1 note at a pixel density of 855 million dots per square inch. Each individual image of the pyramid consists of 6,982 dots.
 
According to Mirkin, “Hard-tip, soft-spring lithography is to scanning-probe lithography what the disposable razor is to the razor industry. This is a major step forward in the realization of desktop fabrication that will allow researchers in academia and industry to create and study nanostructure prototypes on the fly.”
Added Dr. Young-Kook (Ryan) Yoo, VP of Global Sales and Marketing at Park Systems, “Developing a potential hard-tip, soft-spring lithography method is great news to Park Systems, the users of our high-performance XE technologies, and the wider lithography-imaging community, offering enhanced potential to interrogate nanoscale environments with accuracy, sensitivity and functionality.” He noted that HSL could be used to develop new approaches to medical diagnostics, pharmaceutical development, printable circuits, and other emerging nanoscale technologies.

Single Molecule Conductance of DNA Bases and Sequencing by Tunneling; Imaging Nucleic Acids with the AFM
Running time: 56 minutes
April 8, 2009
Speakers: Stuart Lindsay, PhD Arizona State University, Edward and Nadine Carson Professor of Physics and Chemistry Biodesign Institute; W. Travis Johnson, PhD, Research Scientists, Agilent Technologies

Single Molecule Conductance of DNA Bases and Sequencing by Tunneling.
The scanning probe microscope is a great tool for measuring the conductance of single molecules. Tunneling current measurements are sensitive to the hydrogen bonding between base-pairs, while measurements of the conductance of base-nucleoside pairs yields a value for their absolute conductance, opening the way to design of a device that sequences DNA by means of tunneling measurements.

“Imaging Nucleic Acids with the AFM”
Atomic Force Microscopy (AFM) can be used to obtain highly accurate, nanometer scale images of nucleic acids, including DNA and RNA, in air or in physiological conditions. This makes the AFM a powerful analytical tool to study the structure and function of DNA. In this seminar the study of nucleic acids via AFM will be discussed and explored.
