A Research Group Led by Professor Sokolov has Presentations Featured at the Annual American Physical Society’s Meeting

Two presentations, of Clarkson University’s research group led by CAMP Professor Igor Sokolov, have been selected by the American Institute of Physics as featured presentations at the American Physical Society’s (APS) Annual Meeting held in Baltimore, Maryland during the month of March. The team’s presentations were chosen along with fifty others from a collection of over 6,500 submitted abstracts. Professor Sokolov’s group includes Professor Craig Woodworth, research associate Dr. Iyer, and graduate student Venkatesh Subba Rao.

The first presentation by the group focused on a potential cure for the increased rigidity of old human epithelial cells. This increase in rigidity was previously discovered by the Clarkson team. They have now shown that the greater rigidity is correlated with an increase in the density of specific cytoskeletal fibers.

“We used Atomic Force Microscopy (AFM) in combination with immunofluorescence microscopy to determine the chemical nature of the fibers associated with the increased rigidity,” explained Professor Sokolov. “Having found that out, we used special cytotoxic chemicals to decrease the amount of these fibers in cells, thus reducing the effects of aging.”

Through experimentation, the team found that by using certain concentrations of the chemicals, old cells did not die, but rather returned to their youthful level of rigidity.

The group’s second presentation described the study of molecular differences between the surfaces of normal and cancerous cells. “This is the first research to explore the mechanics of the cell’s surface, and we have found that it is even more complex than first thought. However, because of the complexity, it leaves us with a novel approach for cancer detection where cells can be identified using the principle of physical adsorption rather than traditional biological methods,” said Professor Sokolov. “This finding may definitely be applied for the detection of cancer.”

The American Physical Society was founded in 1899 at Columbia University. It is the mission of the Society "to advance and diffuse the knowledge of physics," and since its creation has been at that task. In more recent years, the activities of the Society have broadened considerably. The APS is active in public and governmental affairs, and in the international physics community. In addition, the Society conducts extensive programs in education and public outreach. The APS has 14 divisions and nine topical groups covering all areas of physics research. There are six forums that reflect the interest of its 43,000 members in broader issues, and eight sections organized by geographical region. The annual APS meeting is a central event of the society.

 

Professor Sergiy Minko, the Egon Matijevic' Chaired Professor of Chemistry

Clarkson Professor Sergiy Minko is Editor of a New Book about Responsive Polymers

Professor Sergiy Minko, the Egon Matijevic' Chaired Professor of Chemistry at Clarkson University, is the Editor of a new book about responsive polymers. The book, titled Responsive Polymer Materials: Design and Applications, was released in the United States in January and published worldwide in March. It includes fourteen chapters authored by leading polymer researchers from around the world. These researchers offer practical insights into the latest developments in responsive polymers, such as polymers engineered to alter structure and properties in response to environmental stimuli. The book includes important new material to help chemists, biochemists and electronic engineers better understand and characterize molecular and submolecular assemblies that enable the fabrication of switch-driven polymer systems. In addition this book demonstrates how the properties of responsive polymers such as morphology, wetting behavior, adhesion, roughness, and permeability can be modified to create and improve biomedical devices, chemical sensors, microfluidic devices, drug delivery systems, adhesion systems and self-regulating colloids.

Professor Minko’s research focuses on the areas of smart/responsive polymer materials, smart colloids, nanostructured thin polymer films, the formation of nanowires and nanoparticles, adhesion, wetting, adsorption regulations and single molecule devices. He received his doctoral degree in organic chemistry from Lviv Polytechnic University in 1983 and a doctorate of science in macromolecular chemistry in 1993 from the Institute of Physical Chemistry at the National Academy of Science in the Ukraine. Professor Minko is a member of the American Chemical Society and the American Physics Society. Also he holds 14 patents and has authored more than 100 articles for professional publications.
