Written on December 13, 2013“Colloid Science Collides with Liquid Crystals” perspective is featured in the December 13, 2013 issue of SCIENCE magazine. The perspective discusses a “a strikingly elegant study where Turiv, et al. unmasks a new example of “anomalous diffusion: of colloids that involves a liquid crystal (LC), a liquid-like phase that has long-range orientational ordering. Fluctuations in the solvent-molecule orientations cause MSDs of colloids to grow nonlinearly with time.”

Written on November 09, 2012Recent research by Thrust 3 has demonstrated that the interactions that arise between nanoparticles suspended in a liquid crystal can be manipulated over multiple orders of magnitude (ranging from 1 to 100 kBT) through control of the particles’ surface chemistry and their radius. Previous work with micron sized particles had established that particle-particle interactions are extremely strong and essentially irreversible. The Thrust’s results are significant in that they demonstrate that interactions between nanoparticles are fundamentally different from those between micro-particles, and they can in principle be controlled to yield reversible, equilibrium assemblies for potential applications in devices.
Written on November 09, 2012Thrust 2 has used the predictable, three-dimensional side chain patterns generated by β-peptides with single-molecule force spectroscopy to quantify how changes in nanometer-scale chemical patterns affect intermolecular interactions, with a particular focus on understanding hydrophobic interactions. In addition, and significantly, Thrust 2 used their findings to enable additional exciting discoveries regarding the way in which proximal charged groups influence hydrophobic interactions. Overall, these experiments performed by Thrust 2 elucidate two influences of proximal cationic groups on hydrophobic interactions, and broadly validate an experimental system that has the potential to substantially advance our understanding of intermolecular forces associated with hydrophobic domains on the molecular length scale.
Written on November 09, 2012NSEC continues to support the Materials Science Center (MSC) in the area of CryoTEM equipment, by replacement of the aging LEO 912 EFTEM, with a Tecnai T12 which has been upgraded for CryoTEM. For the first time on campus, a researcher in the Department of Neurology was able to use our NSEC funded equipment to prepare 70 plastic embedded sections with our ultramicrotome, and image them in the Tecnai T12 129KV TEM now in the Materials Science Center. The images were then processed in a extension if the ImageJ software called Fiji, being developed by the Laboratory for Optical and Computational Instrumentation at UW (supported by NIH) to produce an aligned 3-D model of the structure of a mouse motor neuron synaptic junction.
In addition, the NSEC supported a successful joint NSEC, Botany and BioChemistry NSF MRI proposal for an advanced 300KV FE(S)TEM that will bring automated EM tomography capability to UW-Madison.
Written on November 09, 2012Thrust 3 has pioneered the use of optical mapping for high-throughput analysis of genomic DNA. An important step taken by the Thrust was the prediction and the corresponding demonstration that giant DNA “dumbbells” , produced by trapping the molecules in long nanoslits, enable stretching of genomic DNA well beyond previously possible (to nearly 100 % of the molecules’ contour length), thereby providing optical maps with single nucleotide resolution, and leading to the first demonstration of a full genome analysis by nanocoding.

Written on April 04, 2011Using an advanced form of a rubber stamp, researchers have developed a way to adhere an ultra-thin antibacterial coating to a wound.
The active ingredient, silver, "has been used to prevent and treat infections for ages," says first author Ankit Agarwal, a postdoctoral fellow in chemical and biological engineering at the University of Wisconsin-Madison. "But silver can also kill skin cells, and therefore we need to develop materials that deliver antibacterial but nontoxic levels of silver to wounds."In a study just published in the journal Advanced Functional Materials, Agarwal, chemical and biological engineering professor Nicholas Abbott, and colleagues described a process for creating a transparent ultra-thin polymer coating carrying precise loads of extremely fine silver nanoparticles.
The coating, just a few molecules thick, was assembled on a flexible piece of rubber and then rubber-stamped onto a piece of cadaver skin that simulated a wound in the experiment.
To test the activity against bacteria, the researchers treated skin samples with two bacteria that commonly infect wounds. Using a silver dosage that had not harmed skin cells in previous tests, the bacteria were undetectable within 12 hours, Agarwal says.

Dietram Scheufele, professor of life sciences communication at the University of Wisconsin-Madison, is the winner of the 2010 Krieghbaum Under-40 Award from the Association for Education in Journalism and Mass Communication.
The award, named for former New York University professor Hillier Krieghbaum, goes to young association members for achievement in teaching, research and public service, which Scheufele considers a tidy description of the Wisconsin Idea.
"Service to society at large is important to us at Wisconsin and important to my work, which actually often cites Krieghbaum," Scheufele says. "Krieghbaum was dealing with some of the same issues we're dealing with today. How to we build bridges between society and the science we're doing at universities today?"

With funding from the National Science Foundation, a University of Wisconsin-Madison engineer will study whether "drag-reducing" polymer molecules enhance flow through some of the tiniest blood vessels in the human body. Smaller than the diameter of a human hair, capillaries are embedded within the body's organs and are important for distributing blood throughout the tissues. "One of the issues is making sure that, under situations where there's a disease or injury, blood is still able to get to where it needs to be," says Michael Graham, Harvey D. Spangler Professor of Chemical and Biological Engineering at UW-Madison.

Genetic abnormalities are most often discussed in terms of differences so miniscule they are actually called "snips" — changes in a single unit along the 3 billion that make up the entire string of human DNA.
"There's a whole world beyond SNPs — single nucleotide polymorphisms — and we've stepped into that world," says Brian Teague, a doctoral student in genetics at the University of Wisconsin-Madison. "There are much bigger changes in there."
Variation on the order of thousands to hundreds of thousands of DNA's smallest pieces — large swaths varying in length or location or even showing up in reverse order — appeared 4,205 times in a comparison of DNA from just four people, according to a study published May 31 in the Proceedings of the National Academy of Sciences.
Those structural differences popped into clear view through computer analysis of more than 500 linear feet of DNA molecules analyzed by the powerful genome mapping system developed over nearly two decades by David C. Schwartz, professor of chemistry and genetics at UW-Madison.

By adding a subtle nudge to each of more than 1 billion search requests every day, Google may be steering the direction of public discussion. Begin typing a word in the search box at google.com, and the Google Suggest feature starts kicking in ideas - "tiger" begets "tiger woods," "tea" draws "tea party movement" and "craig" will summon "craigslist." "It is meant to be helpful, but from a public discourse perspective it is worrisome," says Dominique Brossard, a University of Wisconsin-Madison life science communication professor. Brossard and four colleagues studied Google''s data for nanotechnology-related search terms and the associated Google suggestions from October 2008 to September 2009. In a study published in the May issue of Materials Today, the researchers found a reversal in the top 10 nano search terms, with economic impact (word such as "stocks," "jobs" and "companies") searches giving way to health ("medicine" and "cancer") searches over the course of a year.

Scientists have no problem making a menagerie of nanometer-sized objects — wires, tubes, belts, and even tree-like structures. What they sometimes have been unable to do is explain precisely how those objects form in the vapor and liquid cauldrons in which they are made.
Now a team led by University of Wisconsin-Madison chemist Song Jin, writing this week (April 23, 2010) in the journal Science, shows that a simple crystal defect known as a "screw dislocation" drives the growth of hollow zinc oxide nanotubes just a few millionths of a centimeter thick.
The finding is important because it provides new insight into the processes that guide the formation of the smallest manufactured structures, a significant challenge in nanoscience and nanotechnology. "We think that this work provides a general theoretical framework for controlling nanowire or nanotube growth without using metal catalysts that can be generally applicable to many materials," says Jin, a UW-Madison professor of chemistry.

In four years at UW-Madison, Mahesh Mahanthappa, Assistant Professor of Chemistry, “has rapidly distinguished himself as the outstanding young teacher in our department,” writes nominator Robert Hamers, chair of the Department of Chemistry. In the fall of 2007, Mahanthappa received the highest evaluation score of any faculty or staff member in any undergraduate course, and he has continued that excellence since.
“Professor Mahanthappa’s ability to communicate is the first step in his magic as a teacher, because in captivating a room of 250 freshmen by talking about chemistry, he sets the stage to teach meaningfully and to inspire students in a way rarely accomplished,” writes student Lauren Buckley. “All professors know the material they teach and most find it fascinating, but Professor Mahanthappa’s ability to share both his knowledge and excitement is a defining factor of his effectiveness as a teacher. He showed you that if you knew the concepts and were immersed in the language of chemistry, you would eventually learn it like you do any foreign language.”
