CFN Research Activities

Dr. Tkachenko works on a variety of problems in Theoretical Soft Condensed Matter, with special focus on programmable self-assembly and biologically-inspired nanotechnology.  In particular, he is one of the pioneers of  theoretical studies of DNA/nanoparticle and DNA/colloidal systems. The strategic objective of this research is to use the highly specific bimolecular interactions (e.g. between complementary DNA) for programmable nano-architecture, and for design of functional nanostructures. Much of this research is done in close collaboration with CFN Soft/Bio Nanomaterals group, as well as  with CFN user community.
