Our research is published in #1 general chemistry journal
Olena Kudina and Andriy Voronov, in collaboration with Scott Pryor, Associate professor in Agricultural and Biosystems Engineering at NDSU, group and a research group from Clarkson University published their recent research in Angewandte Chemie International Edition, leading journal in general chemistry.
The work is entitled “Highly Efficient Phase Boundary Biocatalysis with Enzymogel Nanoparticles” and introduces principally novel mechanism of biocatalysis – phase boundary biocatalysis, when being encapsulated the enzyme molecules (biocatalyst) remain mobile in a soft (polymer) carrier. Not only this unique finding can be explored for localized highly efficient bioconversion processes, but also it opens a new avenue for variety of applications, including drug delivery and absorbable implants. The uniqueness of these capsules is in their ability to protect enzymatic activity, enable simple reuse/recovery of enzymes, and provide an efficient way to regulate enzymatic reactions. It is expected that the developed technology will enhance enzyme efficiency during bioconversion and reduce cost of biocatalyst.
With its current Impact Factor (IF) of 13.734 the Angewandte Chemie, is at leading position among the general chemistry journals. The journal appears weekly and is one of the prime chemistry journals in the world, with an IF higher than those of comparable journals.
The published manuscript is co-authored by Sergiy Minko, Professor of Clarkson University in Potsdam, NY, his students Andriy Zakharchenko and Alexander Tokarev, as well as by group of researchers from Institute of Polymer Research in Dresden, Germany, and Olena Kudina, graduate student in Voronov’s group at NDSU.

Olena worked five weeks in Mayo Clinic
During October – November, Olena worked for five weeks as a research trainee in Mayo Clinic, Rochester, MN. She was working as a part of research team in Orthopedic Surgery Department (the group led by Dr.Michael J. Yaszemski) under supervision of Dr. Maran Avudaiappan on Mayo Clinic main campus. Olena’s research was a part of collaborative project between two groups on developing novel responsive polymer drug delivery systems for treatment of bone cancer (osteosarcoma). These drug delivery systems are based on amphiphilic invertible polymers recently synthesized in Voronov’s group. Novel polymeric carriers were tested for delivery of natural drug candidate – curcumin.
Mayo Clinic is one of the world’s leading health care and research facilities, ranked as the #3 overall hospital in US. Scientists working at the Mayo Clinic research facilities are conducting extensive research on understanding diseases (in particular, cancer research) as well as translation of possible treatments into practice.

Two new papers on New Oligomers Synthesis are published
Our work titled “PEG and Cholesterol-Containing Pyromellitates: Synthesis and Self-Assembly” authors, Olena Kudina, Ihor Tarnavchyk, Olena Khomenko, Olga Budishevska, Stanislav Voronov, Andriy Voronov, was recently published in Wiley journal Macromolecular Chemistry and Physics. In this work we report about synthesis of novel biocompatible and biodegradable macromolecules comprised of cholesterol that self-assemble an aqueous solutions. The synthetic approach provides a direct way to control macromolecular self-assembly. High solubilization capacity and biodegradability of assemblies, as well as other colloidal properties (size distribution, etc.), make the synthesized macromolecules good candidates for biomedical applications, including drug delivery.
Another paper titled “Amphiphilic oligomers based on diesters of pyromellitic acid for the solubilization of lipophilic agents” authored by Оlena Khomenko, Olga Budishevska, Аndriy Voronov, Оlena Kudina, Ihor Tarnavchyk and Stanislav Voronov will be published in Avestia journal International Journal of Theoretical and Applied Nanotechnology. The paper describes the synthesis, micellization and solubilization of new amphiphilic oligomeric surfactants, diesters of pyromellitic acid. The surface active oligomers of this type can be used for various applications such as surfactants for emulsion polymerization, for the development of drug delivery systems, etc.

Paper in Reactive and Functional Polymers is published
Our paper work titled ‘A novel copolymer of N-[(tert-butylperoxy)methyl]acrylamide and maleic anhydride for use as a reactive surfactant in emulsion polymerization‘ authored by Andriy Popadyuk, Ihor Tarnavchyk, Nadiya Popadyuk, Ananiy Kohut, Volodymyr Samaryk, Stanislav Voronov, Andriy Voronov was published in Elsevier journal Reactive and Functional Polymers.
In this paper we reported about a new copolymer that was synthesized and employed as a reactive surfactant (inisurf) for the emulsion polymerization of styrene to yield surface-functionalized (peroxidized) reactive latex particles.
