Abstract : Modern medicine does not exist without drugs, but the drugs are not useful without proper delivery systems. Drug delivery systems have advanced during the last five decades from the primitive powder formulations to the programmable delivery systems. The drug formulations range from fast-dissolving tablets which are designed to release a drug in a matter of seconds to drug-eluting stents delivering a drug for several months. Despite these advances, new drug delivery technologies remain to be developed, especially for drug targeting, long-term delivery, and site-specific drug delivery. Recent progresses in nanofabrication have allowed preparation of nano/micro structures that are ideally suited for various controlled release applications. This presentation deals with how new smart polymers and current nanofabrication techniques can be used for developing better formulations for the future. Bio: Kinam Park is the Showalter Distinguished Professor of Biomedical Engineering at Purdue University. He received his Ph.D. in pharmaceutics from the University of Wisconsin in 1983. He currently holds a joint faculty appointment at Purdue in the Departments of Biomedical Engineering (BME) and Industrial & Physical Pharmacy (IPPH). His research has been focused on the use of various polymers and hydrogels for controlled drug delivery. His current research includes homogeneous microparticles using nano/micro fabrication, hydrotropic polymeric micelles, superporous hydrogels, fast melting tablet formulations, and drug-eluting stents. Professor Park is the 2009 recipient of the Sigma Xi Faculty Research Award at Purdue University. This award is presented annually to a researcher at Purdue University in recognition of outstanding research contributions. This seminar is being co-hosted by the Departments of Biomedical Engineering and Industrial & Physical Pharmacy, as well as the Purdue University Chapter of Sigma Xi.

After briefly reviewing various options for nanofocusing in free space by using near-field phase conjugation [1], linking it to the recent developments in nanofocusing [2] and cloaking [3], the radiation nanofocusing by making use of suitable surface plasmon (SP) modes supported by metal waveguides, i.e. the SP modes that scale down in size linearly with the waveguide cross section, is discussed. Nanofocusing of channel plasmon polaritons (CPPs), which are SP modes supported by grooves cut into metal, is considered in detail, not only presenting the underlying physics involved but also reporting on design, fabrication, characterization and modelling of radiation CPP nanofocusing with subwavelength gold grooves being gradually tapered synchronously in depth and in width. Efficient CPP nanofocusing at telecom wavelengths with the estimated field intensity enhancement of up to ~ 90 is directly demonstrated using near-field microscopy and careful electromagnetic simulations predict more than 1000-fold intensity enhancements [4], opening thereby exciting perspectives for practical exploitation of the CPP-based nanofocusing. Another promising approach is to actually implement an original idea by Nerkararyan [5] of radiation focusing in tapered gaps, an approach that allowed us to achieve the intensity field enhancement of ~100 at the gold groove bottom (under normal illumination) [6]. Further developments and possible applications of the plasmonic nanofocusing phenomena are also discussed. Bio : Sergey I.

He joined the Department of Physics and Nanotechnology, Aalborg University (Denmark) in 1991, becoming a professor in physics in 2003. Since February 2008 he is a professor in nano-optics at the University of Southern Denmark (Odense), heading research activities within plasmonics and near-field optics.

Prokhorov Institute of General Physics, Moscow Institute of Physics and Technology. Abstract: With the advent in scientific language the terms «negative refraction coefficient» or «negative refraction» as well as related terms, researchers put some questions, which generally speaking have a much broader significance than the above words. The notion of «negative refraction coefficient» was shown for the first time probably in our early work . However, we have shown that a simple substitution of negative values n in some formula of electrodynamics and optics often leads to grave mistakes. Moreover, if the phase and group velocity are antiparallel, you must be very careful with some other formulas, which are not directly included value of n. This applies, for example, to the very well known formula P=hk , linking the value of the photon linear momentum with its wave vector. It is obvious that in the case of negative wave vector k , this formula gives a negative value for the photon linear momentum, and thus in case of the light absorption light pressure should be replaced by light attraction. This is all the more imperative that, strangely enough, the value of the photon linear momentum, even for the usual matter with positive case is a subject of debate for over 100 years . This discussion is based on the existence of two completely different energy-momentum tensors for electromagnetic fields, namely tensors in Minkowski form and in the form of Abraham. They give different expression for the forces in the transparent body by passing it through the electromagnetic radiation. Interesting to note that the tensor of Abraham in fact is not a tensor, because it is not a relativistic invariant. As to the Minkowski tensor, its use leads to some unusual expression for the masses, transferred by the radiation from the emitter to the receiver (values vph and vgr are phase and group velocities accordingly). >From this expression becomes clear, that in the case of negative refractive index the mass is transferred not from the radiator to the receiver, but in opposite direction from the receiver to the radiator. The above considerations indicate that relations and are not simultaneously compatible with wave-particle duality principle .
