DNA sequence-dependent photoluminescence enhancement in a cationic conjugated polyelectrolyte

Chem Commun (Camb). 2014 Oct 7;50(77):11311-3. doi: 10.1039/c4cc03417a.

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.
