Leonardo Golubovic, Ph. Morgantown, WV 26506 -6315. Phone: 304-293-5195. Realistic physical systems are comprised of an enormous number of atoms and statistical physics must be used to understand their properties.
This an interesting area of research for four reasons: (1) it studies diverse physical systems such as superconductors, liquid crystals, bio-membranes, and polymers, (2) there are many new and extremely novel theoretical ideas and approaches nowadays used in this field, (3) there are a huge number of important experiments being done, and many more that could be done, and (4) the entire field stands at the interface between physics and the fields of biology, chemistry, engineering, and materials science. Most of my theoretical research is in the statistical physics of surfaces&interfaces occurring in condensed matter systems. I investigate fluctuations and phase transitions in bio-membrane systems. This research is interesting also for a seemingly remote field of oil-recovery in which huge bio-membrane like interfaces occur in fascinating complex fluids known as microemulsions. Also, I investigate interfaces of solids growing in the presence of atomic fluxes. Here I want to understand statistical properties of these rough interfaces, and various interfacial instabilities recently found in molecular beam epitaxy.
I have applied theoretical ideas from the growing interfaces physics to resolve some difficult problems in a more traditional field of smectic liquid crystals. Another area of my recent research is statistical physics of lines, such as bio-polymers and flux lines in superconductors. I have investigated the dynamics of flux lines moving through disordered superconductors, and classical&quantum fluctuations of long semi-flexible molecules and rods. This work is of interest in the emerging field of molecular nanotechnology. Biomacromolecular systems, such as the DNA -cationic lipid complexes used in gene therapy applications, are inherently capable of forming interesting condensed matter structures. These complexes have exemplified novel and unusual liquid crystalline states of matter such as the unusual Sliding Phase which I have revealed and elucidated in my theoretical studies. Prominent role in this area is played by the cationic-lipid membranes supported on solid surfaces, due to the fact that naturally anionic DNA adsorbed on such membranes is highly laterally mobile.
In a recent work, I have addressed a basic physics questions: What happens with the large-scale conformations of semi-flexible polymers, such as DNA molecules, once they are adsorbed on curved, periodically structured surfaces? With my experimental colleagues, I have explored the behavior of DNA molecules adsorbed on electrically charged, cationic-lipid membranes prepared on grooved, periodically structured substrates. We have revealed a striking ability of these periodically micro-structured membranes to stretch DNA coils. We elucidated this phenomenon in terms of an interesting DNA localization transition prone to play a significant role in future biophysical and biotechnological investigations. As a contribution to an ongoing quest to unfold the coiled and therefore inaccessible state of DNA in its natural 3-d environment, our study initiates a new venue for controlling conformations of semi-flexible biopolymers by employing their interactions with specially structured biocompatible surfaces. On the practical side, in contrast to presently employed micro-fluidic methods, our new approach to stretch DNA coils avoids any use of fluid flows and the throughput limitations due to the difficulties in entering DNA into micro-fluidic channels.
Indeed, the DNA can be easily brought in large amounts onto our periodic membranes. Importantly, to be stretched by our approach, DNA need not be confined into small spaces of micro-fluidic channels. Rather, the stretched DNA molecules are freely exposed to a larger surrounding water medium and all the molecules dissolved in it. Due to this feature, our new way to stretch polyelectrolytes may facilitate more direct, high throughput protocols and experimental studies of fundamental biological interactions between DNA and other bio-molecules.
