The necessity to increase the treatment efficiency in medical and pharmaceutical fields has led to the improvement of the already existing drug carriers and to new methods for the development of drug delivery systems with various sizes, morphologies and properties. The ZwitterZein project objective is to design novel macromolecular supports based on zwitterionic porous microparticles containing zein and betaine moieties in order to obtain efficient drug delivery systems for both hydrophobic and hydrophilic drugs as well as novel antimicrobial materials with possible medical applications. The Zwitterzein project specific objectives are the development, characterization and testing of zwitterionic microparticles containing zein and betaine moieties, as complex drug vehicles for targeted delivery: (OS1) synthesis of porous crosslinked microparticles based on glycidyl methacrylate, N-vinylimidazole and various crosslinking monomers, (OS2) preparation of novel zwitterionic porous microparticles containing zein and betaine moieties, (OS3) core/shell composite construction by in-situ CaCO3 crystallization on porous microparticles, (OS4) complex characterization of all obtained materials, (OS5) study of zwitterionic porous microparticles antimicrobial activity and their drug loading/release capabilities.

Abstract:

Quartz sand/polyelectrolyte composite materials with controlled morphology and structure at nanometric level are a very interesting class of materials which can be used as solid phase for waste or surface waters treatment. Their unique properties (hardness from the inorganic part and softness from the organic one) could be exploited in the column separations of organic/inorganic pollutants dissolved in aqueous media. The project „Quartz sand/polyelectrolyte composite microparticles with high loading/release of some inorganic/organic compounds from polluted waters” (Acronym: POLYSAND) has as main scope to improve the treatment efficiency of polluted waters resulted from different industries, by reducing the content of metal ions and organic compounds, by means of using innovative, affordable and ecofriendly materials as complex sorbents based on quartz sand and natural/synthetic polymers, thus contributing to the decrease of polluted waters and a thus to a better water quality. The project scope is to obtain cross-linked polyelectrolyte arhitectures deposited onto different quartz sand microparticles with potential applications in water purification. The project POLYSAND propose a novel and innovative solution: the combination of different materials (quartz sand and polyelectrolytes), which work with different adsorption mechanisms, in one adsorption advanced material. This gives the opportunity to simultaneously remove different types of pollutants (metal and organic substances) and addressing the variations of pollutant types and concentrations of different polluted waters. The project POLYSAND propose a new and innovative eco-nano-technology for composite sorbent advanced material synthesis - polyelectrolyte precipitation onto sand surface from high concentration of polymer chains - which will increase the deposited amount of cationic polyelectrolyte relative to the sand volume followed by eco-friendly chemical/thermal cross-linking of organic arhitecture.

Abstract:

This project is focused on the preparation and characterization of novel porous ionic multicomponent matrices as thin films, monoliths and membranes, with tailored architectures and responsiveness and on their specific capabilities to host and to control deliver of bioactive compounds. Porous ionic materials selected as hosts in the frame of the project are hydrophilic, mainly multicomponent, consisting of physically or chemically stabilized architectures, characterized by a permanent porosity. Ionic thin films will be achieved by the layer-by-layer technique mainly from weak synthetic and natural polyelectrolytes, their interaction with biopolymers and their potential biomedical applications being evaluated. Cryogels, by their unique heterogeneous open porous structure allow unhindered diffusion of solutes and bio-objects. Ionic interpenetrated polymer networks as cryogels, prepared for the first time in the frame of this project, open novel directions for fundamental research and separation science. Ionic functionalities and the presence of pores make these materials suitable for biomedical applications, drugs and protein release, chromatrographic separations, water remediation, etc. Novel multiple responsive (temperature, pH, ionic strength) multicomponent cryogels having a high biocompatibility will be also prepared in the frame of the project.
