title: DNA sequence-dependent photoluminescence enhancement in a cationic conjugated polyelectrolyte.
abstract: DNA sequence-dependent photoluminescence enhancement is found for a cationic polyelectrolyte complexed with single stranded DNA and described as a result of an interplay between electrostatic attraction and the π-π stacking between the polyelectrolyte's backbone and DNA's bases.
