Research

   The research focus of our group is aimed at the design, synthesis and evaluation of novel polymers and copolymers with unique architecture, composition and properties that can be used for advanced applications. The synthetic projects involve extensive use of various methods for organic functional group (trans)formation, polycondensation techniques and multiple procedures for controlled or "living" chain-growth polymerization. State-of-the-art methods are used for isolation, identification and characterization of the macromolecules formed including size-exclusion chromatography with multiple detection, FT-IR, UV-Vis, Fluorescence and NMR spectroscopies, MALDI-TOF spectrometry and microscopy. The biological activity and biocompatibility of selected materials are evaluated in collaboration with other research groups and laboratories in USA and Europe. The combination of these methods places our research at the interfaces of organic chemistry, polymer science, biotechnology and molecular medicine (see a recent news reports on our activities in this area  https://nccnews.expressions.syr.edu/health/suny-esf-researchers-seek-revolutionary-cancer-treatment/ and https://www.researchgate.net/profile/Ivan_Gitsov

   Our efforts are almost equally divided between the creation of novel macromolecular architectures (linear-dendritic copolymers and hydrogels, hyperbranched macromolecules and linear-hyperbranched copolymers) and the evaluation of these materials for novel biomedical applications (polymeric prodrugs, systems for covalent or passive drug binding and sustained delivery) https://blog.suny.edu/2015/06/can-we-improve-cancer-treatment-with-the-tiniest-of-nanoparticles/ and for new biotechnological uses (formation of unique semi-artificial enzymes through site-specific nano-contacts and no chemical / genetic modification of the proteins).

   A leading motif throughout our research is the development and use of “green” and sustainable chemistry practices.

Thanks to the hard work and devotion of our students our research was ranked among the top 2% of most cited worldwide (among the top 1 % in polymers): https://doi.org/10.1371/journal.pbio.3000918
