The self-assembly of supramolecular complexes of nucleic acids and polymers
is of relevance to several biological processes including viral and
chromatin formation as well as gene therapy vector design. We now show that
template polymerization facilitates condensation of DNA into particles that
are <150 nm in diameter. Inclusion of a poly(ethylene glycol)-containing
monomer prevents aggregation of these particles. The DNA within the
particles remains biologically active and can express foreign genes in
cells. The formation or breakage of covalent bonds has until now not been
employed to compact DNA into artificial particles.
