In the frame of “PENED 2003” 
program funded by the Greek General Secretariat for Research and Technology
(duration : 3 years)
“Study of hyperbranched polymers  and their complexes with linear 
polyelectrolytes as
 solubility enhancement and controlled-release agents”

Titles of the theses:

1. "Thermodynamic study of solutions of hyperbranched polymers" (Theory-
Experiment)


Despite the strong interest attracted to dendrimer and hyperbranched systems,
 not only as drug-delivery agents but also as important constituents for a 
wide 
range of other applications, our current understanding of  their thermodynamic 
properties in solution is still limited. There is only segmented information 
which however suffices to indicate the complexity and the unique 
characteristics 
 of their behavior. In aqueous solutions such systems can play the role of a 
multisite 
polyelectrolyte with a complicated thermodynamic behavior, which is intimately 
related to hydrogen-bonding phenomena or other solubility enhancement 
mechanisms. 
Target of this PhD thesis is to contribute to a better understanding of the 
thermodynamic 
behavior of polyelectrolyte solutions formed by these materials by means of a 
combined 
theoretical (based on the Quasi Chemical Hydrogen Bonding Theory - QCHB) and 
experimental
effort 


2."Study of the physical and chemical characteristics of hyperbranched polymer
   solutions and their complexes with linear polyelectrolytes by molecular 
dynamics
   simulations" (Simulation)


The aim of this thesis is the molecular level examination of the mechanisms 
that
affect the solubility in aqueous solutions of hyperbranched polymers and their
complexes with linear polyelectrolytes, as well as the ability of these 
systems 
for adsorption/entrapment  and controlled-release  of polar molecules. 
Emphasis will 
be given to a detailed (atomistic) representation of the candidate systems in 
order 
to allow as close a comparison with experiments as possible


3. Study of the viscoelastic and transport properties of polyelectrolytic 
hyperbranched
   polymer solutions.  (Brownian Dynamics Simulation – Experiment)


Among the main properties that must be taken into account for the 
appropriateness
of a system to serve as a vehicle for drug (or other biological material) 
delivery,
are the mechanical stability and the level of control of its transport 
properties. 
Target of the 3rd thesis is the study of these properties by a combined effort 
of 
computational (Brownian Dynamics simulations) and experimental techniques 
(Rheology).
