TRANSNADE is designated for the study of the transport properties of nanoscale assemblies and devices fabricated from polymers and polyelectrolytes, such as polyelectrolyte multilayers, polyelectrolyte brushes, polymer micelles, and polymersomes. Transport properties are fundamental for the rational design of delivery devices since the mechanism of transport will finally define release properties. For most of the mentioned nanodevices, transport properties are adjusted in an empirical way. A deeper understanding of the underlying principles and mechanisms of transport of matter is highly desirable. Polymer nanoassemblies in aqueous environments are heterogeneous and at least partly random systems. A complex scenario of interactions for the diffusing species with the nanomaterial can be expected resulting in unusual transport properties. Measuring transport properties at the nanoscale requires novel experimental and theoretical approaches. A multidisciplinary approach is needed, ranging from synthesis, self assembly, to physical chemistry and theoretical physics. TRANSNADE is formed by an international team with the required and complementary expertise. The expertise of Prof. Gao, from Zhejian University , in synthetic chemistry and self assembly together with the expertise of Dr. Moya, from CIC biomaGUNE, in materials science will be paramount for the creation of polymer with specific functions to be integrated on devices and assemblies. Prof. Donath from the University of Leipzig will develop a novel reaction-diffusion approach for diffusion measurements in nanoassemblies. Electrochemical measurements of transport will be performed by Dr.O.Azzaroni, from INIFTA and Dr.Moya will focus on solvent transport by designing an optical setup combined with QCM. Prof.V.Arakelyan from the Yerevan State University and Prof. Donath will join together their expertise in theoretical and soft matter physics to model experimental data and establish a mechanism for transport.
