Special Issue Information

Dear Colleagues,

Synthetic and natural polyelectrolytes have been the subject of fundamental and applied studies for nearly a century. Due to substantial advances both in experimental methods and theoretical approaches, since the 1990’s polyelectrolyte research has undergone a considerable speed-up. On the one hand, interest in polyelectrolytes is spurred by their fascinating properties, such as water solubility, intra- and interchain interactions, the strength of which can be tuned simply by varying salt concentration, and ionic conductivity. These properties make polyelectrolytes attractive from the application-oriented point of view, such as stabilizer of colloidal suspensions, additives to modify flocculation and viscosity, and superabsorbers. Functional polyelectrolytes combine the useful properties intrinsic to polyelectrolytes with added functionality provided by specific features of the polymer backbone, such as delocalized electrons in conjugated chains. Combined functionality can be used to create materials with highly interesting optical, electro-optical, and electronic properties.

On the other hand, the understanding of polyelectrolytes still belongs to the most challenging and most exciting problems in polymer physics and physical chemistry. Despite much effort and substantial progress during the last two decades, much more work is ahead to achieve a quantitative agreement between theory and experiments for a lot of problems, such as counterion condensation, chain stiffness, and formation of complexes. It is still a major open problem to have a satisfactory model explaining the coupling between small ions in solutions and polyelectrolyte charges, which is necessary to understand how electrostatics affects the behavior of polyelectrolytes.

Many biologically relevant macromolecules, such as nucleic acids, polypeptides, and polysaccharides, are polyelectrolytes. Electrophoresis is a well-established method for the fractionation of polyelectrolytes and more specifically, DNA. Hydration-mediated interactions play an important role in the field of biological polyelectrolytes, but are not well understood on nano-scales.

Abstract:
Herein we report on novel zoledronate (ZOL) and simvastatin (SIM) loaded polyelectrolyte complex (PEC) nanoparticles, which can be solution casted on Ge substrates serving as analytically accessible model substrate regarding bone substituting materials (BSM). Four important requirements for drug loaded PEC particles and their films are addressed herein, which are the colloidal stability of PEC dispersions (i), interfacial stability (ii), biocompatibility (iii) and release kinetics in contact to release medium (iv). Dynamic light scattering measurements (DLS) showed, that both poly(ethyleneimine)/cellulose sulphate (PEI/CS) and PEI/dextran sulphate (PEI/DS) particles could be prepared with hydrodynamic radii in the range 35-170 nm and time stability up to several months. Transmission FTIR spectroscopy evidenced that films of both systems were stable in contact to the release medium (PBS) for several days. Immunofluorescence imaging suggested cytocompatibility of cast PEC particle films. Finally, in-situ-ATR-FTIR spectroscopy at cast PEC/drug films at Ge substrates revealed retarded drug releases in comparison to the pure drug film.
