CURRENT RESEARCH
The Andrianov lab uses the polyphosphazene technology platform to develop novel materials for life sciences applications and studies interactions of these macromolecules with biologically important targets. Current projects include the development of potent macromolecular immunomodulators and vaccine delivery vehicles, biodegradable nanoparticulate drug delivery carriers with built-in ‘smart’ intracellular delivery functions, non-covalent PEGylation systems for extending protein half-life, and novel polyelectrolytes for aqueous layer-by-layer assembly of biocompatible, self-healing, fluorinated coatings.
The lab integrates expertise in rational design, controlled synthesis and scaled-up production of these macromolecules, as well as precise formulation and nanofabrication methods. It is equipped with state-of-the-art equipment and expertise for screening macromolecules for critical parameters such as biocompatibility and interactions with important protein targets.
